re: VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...

Thank you for the feedback and comments gentlemen. All of them have been duly noted. Really appreciate it. This is the first time I was fiddling with the front brakes so there was plenty of learning during the process. And I wouldn't say the process is complete since the discs were untouched.

Sorry for the late response!

There are a few minor scratches though. I intend to give her to the detailer this year. It's been a while since a professional detailer has done the job on the car.

Nope, no plans to change the rear drums to discs. I've read up quite a bit on this upgrade and while it actually calls for the rear axle to be changed to be able to fit the discs, most go with the bolt-on upgrade kit with a mounting bracket plate; a purist would hate it though. But as I said before, I am not much of an enthusiastic driver so this would do for now. Maintenance wise, the discs are much easier to work on. I haven't touched the rear drums by myself - would really like to but I hear it is hard with so many springs and bits.

Guys, scratch Aliexpress. Looks like we'll have to switch to eBay.com now. I found a few links selling the 56 mm wheel cap. Take a look:

https://www.ebay.com/itm/333972034773

Might be a good idea to try after a few months due to the current covid scene? Post offices are indeed working but I am not sure of international shipments. The downside with eBay is unless you pay with PayPal, no guarantees with the money-back if we don't get the shipment or it doesn't fit the wheels.

Thad, a colleague who has a 2015 Cross Polo got his car entirely repainted for under Rs 50k INR during March this year from Mount Road VW. Says there was some offer and he wanted to change the car but went with this option to get that new car feeling. Not the perfect job one would expect from the factory but they stripped the old paint, sanded down the minor dents and gave the coats. I haven't seen it myself but the pricing sounds good for a one-time complete repaint from a factory dealership no? With dealerships losing out on sales during this pandemic, they are having such offers to keep them afloat.

Why don't you get the cap from Boodmo? It is delivering to almost everywhere with next to no delays. In the absence of the cap, there are high chances of rusting. As a temporary measure, fill that area with a good quality all-purpose grease.

Yes. We wound some rag cloth at the tip of the screwdriver from the 1/4" ratchet kit, removed the old grease followed by brake cleaner spray.

The piston would get jammed and cause steering wobble. I've experienced this issue twice in my Grand Vitara, and eventually got a new piston.
Thanks! Will keep this in mind. We racked our brains to find a workaround in the absence of a proper C-clamp. So much so that the first thing I did after reaching home was to order a pair of larger C-clamps. Here they are with the 2" one:

Quite a big one for us! I had the driver side wheel back on the hub and all the lug nuts tightened! Never going to forget this for the rest of my life.

That also reminds me to get a large pipe which I can use as a cheater bar to extend the lug wrench. Makes loosening the wheel's lug nuts way easier!

Usually it is the other way round i.e. cleaning the car after the servicing. The issue is with inhaling the dust not getting into the eyes.

Yep, Permatex Ceramic Extreme and this is incidentally the first time I am using it since I am working on the brakes after the 75k km mark.

Well I could blame VW themselves for that since the bottom slider pin of the co-driver side calliper was stuck and pitted (as shown in the snap). It took us some effort to get it off the hole and the grease was in terrible shape.

I'll have the guide pins replaced on both sides when I remove the discs for skimming. Costs about Rs. 850 for one side on Boodmo (link).

You mean a rubber sleeve? From the pair, one of the pins had it (the top sliding pin IIRC) but not the bottom one if you're referring to this:

For just the pad replacements, this works best. Just remove the bolt at the bottom guide pin and you can pivot the calliper to the top. Since we had to remove the pins and clean it, we removed the entire assembly.

I used a tool similar to the one shown below. It has different size 'teeth' on each side. you just have to match them to the piston face and use a ratchet with a 3/8 drive extension to turn it in. It helps if you use a clamp as well as you need a significant amount of pressure to push them in while turning. In that case since the clamp will be covering the 3/8" hole on the top, you can just insert the 3/8" extension in one of the side holes to turn.
Folks from the other side of the planet have access to so many stuff man. I really envy you guys. Stores like Harbor Freight, Lowes, Home Depot etc. I couldn't find the basic piston compressing tool like this anywhere here:

Next time I have several panels to attend to, I could do that. Frankly, though, most of the car is in good enough condition not to warrant it. I have a dent on the tailgate which nobody wants to fix. It's high up, close to the glass. I guess they all think they'll break the glass. The paint is not scuffed though, but you can see the dent when the light falls right.

Last couple of repairs have been at Ignite, but before that, I used to go to Mounts Road. They always did a really nice job with paint and denting.

Much depends on the lifetime of the car. And that may depend on govt suddenly telling us that our diesel engines are too old, and we can't use them any more.

re: VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...

Hey guys, dropping some updates on the ride. Trust all of you are keeping well during these times and hope the worst is behind us. I managed to dodge the virus thus far due to sheer luck and the usual precautions. I was fortunate enough to receive the first shot of vaccination here at Chennai which may not have been possible if I had spent the last lockdown at Palakkad. Anyways, moving on to the updates in no particular order.


Sorting out the High Beam issue:

Finally, after a lot of sweat, the high beam issue was resolved. Just a heads-up though – the next few posts will be helluva long! I’ve described the whole ordeal with several snaps. But this one issue had a lot of learnings involved.

Long story short - one fine day, the high beams stopped working and there was no indication of the high beam symbol on the instrument cluster. Removed the xenon headlamp assemblies, plugged the H4 bulbs into the sockets and realised that the co-driver side high beam wasn’t turning on. Both the low beams were working fine and the driver-side high beam was working. After a LOT of troubleshooting, the issue was narrowed down to a disconnect somewhere in the factory wiring harness and with the help of my FNG technician, the issue was resolved. This also led me to retire the xenon headlight assemblies for good having served the last 6+ years faithfully and reverted to a set of new single barrel headlights with 90/100W bulbs and a relay harness. The whole process is described below in detail.

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-1.jpg

Some of you would know, I had a Morimoto Mini D2S based HID setup retrofitted to the stock single barrel headlights since October ‘14. The entire DIY process has been documented here. The cut-off from the projectors wasn’t the best out there but there was a massive improvement over the stock H4 55/60W bulbs. This setup worked well to this day without any troubles.

Before the last lockdown, I was heading to work as usual and when I pulled the LHS stalk for flashing/passing, I noticed the high beam indication symbol on the cluster missing! This had never happened before. I wondered if the SMD LED for the warning symbol soldered to the instrument cluster’s PCB had conked out! While returning home in the evening, I realised the high beams were not working - not while flashing or if they were engaged. Bigger problems! I decided to sort this out over the weekend. Soon enough, the driver side headlight low beam gave up! This was becoming troublesome and embarrassing now. I wouldn’t drive around with just one headlight which looks very odd like a pirate’s eye patch. It wasn’t too dark in the evenings so I would turn off the headlights and drive back home with the fog lamps. With no high beams and with the driver-side headlight out of order completely, my guess was on the Morimoto relay harness now.

There were 3 problems now:

1. High beams don’t work.
2. There is no indication of the high beam on the instrument cluster.
3. The driver-side low beam also doesn’t work.

At the apartment basement…

That weekend, armed with the required tools, I headed to the basement parking lot. Unplugged both the headlight assemblies and swapped them. i.e. the driver side headlight assy. to the co-driver side ballast + socket and vice-versa. Sure enough, the now driver side headlight assy. wouldn’t turn on while the co-driver side headlight works. So defective bulbs were ruled out; probably, ballast was the culprit. The only missing link is the D2S bulb socket or a loose contact somewhere in the circuit. I fiddled with the sockets and it would intermittently work on and off. So the socket or the short harness from the ballast to the D2S socket on the driver-side had a problem.

I lugged both the headlight assemblies along with the ballasts and the Morimoto relay harness to my apartment. The whole thing was very exhausting back at the basement with no light or proper ventilation and I was in no mood to fiddle around any further. Lo and behold, TN went into a complete lockdown. Which meant my car was going to be parked in the basement with no headlights for days together and this would draw some unwanted attention from the security staff going on rounds and owners of other cars parked in the vicinity. Never mind.

Back to my apartment…

The sockets that shipped with the ballasts in the Morimoto kit back in 2014, came with a right-angled D2S igniter/connector perma-wired to the ballast:

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-2.png

When this is plugged to the bulb in the headlight assy, the cable was taking a sharp bend at the socket and part of the insulation from the cables had worn out exactly at the bend.

(Image clicked after the cable was cut from the ballast)

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-4.jpg

Morimoto never had those straight D2S connectors around that time; they do have them now however. Probably, there was some feedback from existing customers on these right-angled connectors. Because in some headlight assemblies, there is no provision to bend the cable and it has to exit straight from the end.

To resolve the sharp bends on the D2S connectors, I had sourced a pair of D2S sockets with straight leads from Aliexpress (the good ol’ days sigh!):

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-5.jpg

These were purchased way back in Mar ’19:

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-6.png

Check out the differences between the two connectors (Aliexpress one on the left and Morimoto one on the right):

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-7.jpg

I decided to replace the Morimoto’s connector with the straight connector:

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-8.jpg

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-9.jpg

The connector on one headlight assembly was replaced and I threw away the old Morimoto connector to the bin. Big mistake! Why? You’ll find out. I guess life teaches us lessons the hard way sometimes.

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-9a.jpg

In the meantime, the PVC extension pipe I had installed at the rear of the headlight assy had cracked over time (heat from the engine bay + exposure to natural elements).

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-10.jpg

I addressed this issue as well with a new, thicker PVC pipe. Trimmed it to the desired length and I had to grind the innards a bit using the dremel (such a handy tool!):

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-12.jpg

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-14.jpg

The new pipe was a press-fit at the rear; much better than the previous one:

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-15.jpg

With the rubber cap and a couple of cable ties in series (jugaad, if you may but this was replaced with a jubilee clamp later):

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-16.jpg

I have a bench power supply made from a computer power supply (SMPS) and it is very handy for testing various devices at my apartment before installing it in the car. You can read more about it on the DIY thread. The ballast needs a +12V supply to power the D2S bulbs. Just as simple as this:

Name:  17.PNG
Views: 8480
Size:  183.3 KB

And it powered on nicely!

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-18.jpg

I decide to turn off and on the supply multiple times in quick succession to test if it works (simulating high beam passes/flashing) and it was intermittently working; sometime just the arcing sound with no light output. This is definitely not going to cut it if I were to use it in the car. I did not know what was causing this issue. I read up a lot on the internet and there were varied opinions. Some said not to cut the output AC cable from the ballast to the bulb socket, some said a long output cable would cause this issue, some said if the insulation is exposed or not thick enough, it would cause the AC voltage to leak. I was confused!

Instead of using the butt crimp connectors for the ballast’s AC output cables to the igniter, I soldered the two cables together and used two rounds of heatshrink sleeves to insulate the soldered joints. Retested with the bench power supply and the light worked 8 out of 10 times. Randomly, it wouldn’t turn on. I decided to leave this for the time being and concentrated on the co-driver headlight assy.

Additionally, I wanted to replace Morimoto’s relay harness and decided to fabricate my own harness for the assembly. The Morimoto harness worked just fine but what’s that saying again? An idle brain is a devil’s workshop?

I got these parts from GP Road, Chennai – considered to be the Mecca of all things automotive:

- SPST (single pole single throw) relays 12V 40A - 2 nos.,
- SPST relay sockets with leads - 4 nos. (2 for backup; dirt cheap anyway)
- Fuse sockets - 2 nos.
- Fuses 12V 30A - 2 nos.
- Ground terminal lugs - 5 nos.
- 1 sq mm insulated cables of different shades - 2 m each
- 1.5 sq mm insulated cables of different shades - 2 m each

The next day, I began fabricating the relay harness with plenty of trial and error. It sure was fun.

First up, changing the terminals on the relay’s connectors:

The relays from Maruti’s parts bin:

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-25.jpg

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-26.jpg

I used a couple of W5W LED bulbs to simulate the D2S bulb’s output and the projector’s solenoid working for the high beam. I searched the internet for a wiring diagram for a bi-xenon based headlamp setup and came across one on lincolnvscadillac forums:

Name:  27.png
Views: 8057
Size:  112.2 KB

Wired the parts as per this wiring diagram and used my bench power supply to turn the relays on as per low beams and high beams. The LEDs worked indicating the relays are functioning as they should but there was a problem. If the low beam is turned on (i.e. the left relay is turned on), only the HID bulbs should turn on work but as per this wiring diagram, even the right relay would turn on and thereby, the solenoids would receive power. This is wrong and should not work this way. It should be this way:

Low beam - only left relay turns on, HID bulbs turns on.

High beam - both the relays turn on, HID bulbs + solenoids turn on.

I hope this gentleman who shared the wiring diagram on the LVC forum figured this issue out later. That’s when it clicked me, a simple PN diode would do the trick! It would permit current to pass through in only one direction. But what diode should I use here? Searched the internet and landed right on Team-BHP! BHPian graaja had shared this here:

And SirAlec here.

I modified the wiring diagram this way:

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-28.png

1N540X series it was. The first shot of my covid vaccination was due and it was located at a PHC not far from the electronic components outlet I usually frequent. We couldn't get the vaccination shot that day due to the government putting the 18 - 45 age group on hold but I got hold of the diodes promptly.

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-29.jpg

Soldered the diode to the harness and it worked beautifully!

re: VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...

Completed rest of the wiring with the connectors for the solenoids and ballasts, corrugated protective tubing for the cables, zip-tied the bunch.

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-31.jpg

Tested the harness with the actual headlights and that’s when I observed one of the headlights was not turning on occasionally. This was the one with the straight D2S igniter from Aliexpress. And I had thrown away the old Morimoto igniter in the bin which my maid promptly emptied! This turned out to be a big, expensive blunder from my side. I should have preserved the Morimoto D2S igniter!

I opened up the Aliexpress straight igniter and it was a shoddy part:

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-32.jpg

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-33.jpg

At this point, I was very frustrated! I thought enough is enough, slept on it that night and went ahead with the decision to swap them out with a set of new, stock headlights. The xenon setup had served me faithfully all this while for the last 6+ years with so many night drives I had undertaken from Chennai to Palakkad and back. This was also our first intense DIY that my good friend Moorthy and I did, which lasted close to two weeks. Man, I was definitely going to miss that nice, sharp cut-off with the blue hue and the fun of flicking the high beams like the camera flashes. It used to turn so many heads when the coming-home and leaving-home lights would turn on at the parking. But as they say, all good things must come to an end and thus, I chose to gracefully retire the bi-xenon setup.

So what went wrong really?

1. The Morimoto ballast on my setup had the output AC cable permanently connected to the ballast.

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-34.png

The later units from Morimoto came with removable input and output connectors for the ballast like this:

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-35.jpg

So replacing the bent igniter cable with a straight one wasn’t possible without splicing the AC output cable.

2. The Aliexpress’ straight D2S igniter cable failed to work properly. Guess one can only expect so much from a cheap cable.

Is there any way I can reuse the bi-xenon headlight assembly? Yes, with a new ballast unit. I’ll save it for later in case I change my mind. Unlikely but still an option. The headlight assembles were safely packed in the boxes. Never going to part with those and maybe, just maybe, I will fix them up some day. :’)

So what next? I had to invest in a new set of headlamps. Having heard not very good reviews of the dual barrel headlights with the H7 bulbs + being twice as expensive as the single barrel headlights, I decided to settle for the cheaper, single barrel headlights with the H4 bulbs and use a set of 90/100W bulbs with a good quality relay harness. I could have modified the DIY harness I had fabricated but chose against it. Ordered a pair of new headlights from Boodmo and they arrived a few days later in a HUGE box, extremely well packed! Set me back by Rs. 8732.

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-39.jpg

Ordered a cheap pair of Philips 55/60 W bulbs from Amazon for testing and sorting the high beam issue. So the new set of headlights are here. What remained to be sorted was the [/b]high beam issue[/b].

Inserted the bulbs into the stock bulb holders. Turned the rotary switch on for the low beams - both the low beams work properly.

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-40.jpg
(Please excuse the dirty engine bay; I was in no mood to clean the car without resolving this issue first!)

Flicked the stalk for the high beam - only the driver-side high beam turned on. Status quo.

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-41.jpg

Detailed troubleshooting begins:

Step 1 - check the fuses. I used a DMM and checked all the fuses for continuity, secretly praying for one of them to be burnt out. But no, all the fuses were intact.

Step 2 - check the relays. The pre-facelift Polo with the single barrel headlight setup has a SPST relay for the low beam but none for the high beam. So this was technically a moot point but to eliminate the issue, I decide to test the relay anyway. This is the relevant relay for the headlights:

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-42.png

I got home the relay and it was clicking with a +12V supply. I swapped it with the adjacent 646 relay from the relay holder and it was working fine.

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-43.jpg

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-44.jpg

The issue persisted. So a defective relay was also ruled out.

Step 3 - check the rotary headlight switch. Less likely for the switch to be the culprit but I had the Chinese auto-headlight module installed and with it, the aftermarket rotary switch with the Auto option. To rule out the issue of the switch, I requested my folks back in Palakkad to courier me the stock rotary switch with the steering column combination switch (the stalk assembly). With great difficulty in the middle of the government-imposed lockdown, I picked up the consignment from the courier’s depot. Swapped the headlight switch and the issue persisted. The switch was ruled out.

Step 4 - check the steering column combination switch. This was a possibility as I had read a few instances of the metal contact strips inside the assembly melting the adjacent plastic tab. But in that case, the high beam shouldn’t work at all which wasn’t the case here as the driver side high beam was working fine. Replaced the combination switch with the stock unit and much to my dismay, *sigh* the issue continued.

After all the troubleshooting, it finally boiled down to the wiring harness.

Voltages from the connectors were inline with what it should be:

Low:

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-49.jpg

High:

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-51.jpg

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-52.jpg

There was nothing else left to be checked. I had no clue where to begin as the whole harness is taped from the factory. Since I had hit the end of the DIY road, I decided to refer to my trusted technician Jayaprakash (JP) from German Tech garage. Gave him a call and explained the entire ordeal. He suggested bringing the car down. To make his work simpler, I installed the new set of headlights with the 55/60 W bulbs before heading there.

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-53.jpg

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-54.jpg

Fortunately, the TN government had also announced some relaxations for the lockdown including resuming automobile garage operations. I got the e-pass ready and dropped the car on a Monday morn. A few minutes later, another person drops by in his White Vento with his father, looks at my car curiously and asks, “You must be Gannu from Team-BHP?” Hell yeah brother! It was BHPian TurboHead! Glad to have met you bud! No such thing like a garage for a mini-meet yeah? And shortly after, an A6 arrives in a stately style - in a flatbed truck!

The headlight issue was finally ruled out to a pinch in the harness which resulted in the high beam wire to the co-driver headlight to give away. The wires were re-joined and taped properly by JP. It is also worth noting that the high beam indication to the instrument cluster draws signal from the co-driver side high beam.

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-55.jpg

Both the functionalities - high beam and the cluster indication were finally restored.

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-56.jpg

End of an ordeal finally!

Replacing Steering Rack, Front Strut Bushes and Bearings



A one-way trip to home from the garage costs about Rs. 450 - 500 in Uber. Because the car was dropped at my trusted garage, I decided to replace the steering rack, the front strut bushes and the bearings as a part of preventive maintenance. The steering rack was never touched all this while whereas the front strut bushes were replaced with the ECS Tuning ones when the Bilsteins were installed around the 80,000 km mark (link to that post). JP and his team wrapped up all the work done in a day’s time and updates over WhatsApp dropped in promptly. I really appreciate this part.

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-1.jpg

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-4.jpg

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-5.jpg

The steering rack is from Rane Madras Ltd and is apparently, one of the OEM supplier for VW and Skoda for the rack. Part number is 141830092, VW part number is 6RF423057P.

The whole bill came up to Rs. 20,000 which included the price of the new parts.

Adding a relay harness and Philips 90/100W bulbs:



Now that a new set of stock single barrel headlamps were installed, I wanted to improve the performance of the lighting. The cheapest way to do this would be to install a good quality relay harness and 90/100W bulbs. 100/130W would be an overkill and there’s a likelihood of the reflectors going bad over time. The usual contenders for the relay harness were Philips and Hella. There was an Indian company which went by the name Thimson based out of Mysore. Their harness had very good reviews on Amazon! I decided to try my luck with this one. The quality of the cables (Finolex grade with varying gauges), ceramic bulb holders, plastic holders for the fuses, corrugated tubing, heatshrink sleeves was very good. Have to see how well the relay holds up over the years.

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-6.jpg

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-10.jpg

As for bulbs, I picked up a pair of Osram All Season 90/100W bulbs. These seem to have good reviews on Amazon. The HIDs on my previous setup had Osram D2S 35W bulbs and they worked well so that sort of bolstered the faith in Osram once more. Bonus – the bulbs were made in Germany! Come on, don’t we all love car parts made in the Europe? On Amazon, some folks have super high expectations from the product anyway and tend to leave negative reviews. I wasn’t swayed by those anyway and went ahead with the Osram.

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-13.jpg

Installed the harness in a jiffy and based on BHPian Parag’s inputs and his experience with the relay harness and higher wattage bulbs, the ground connections were done properly after scrapping the paint.

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-17.jpg

Verdict – there was a definitive improvement in the lighting performance. However, the headlight diffuser/lens was getting heated up! I wonder how long these would hold up over a proper 10-hour Chennai – Palakkad night drive!

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-20.jpg

Just for kicks, I also used a cheap light meter to measure the maximum intensity over 2 m, 6 m and 12 m for both the 55/60W and 90/100W bulbs.

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-23.jpg

The results from the crude testing at the basement (all other things being constant):

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-24.jpg

But I miss the white light output of the HIDs and the neat cutoff with the blue hue every time the leaving home lights turn on as I park her and walk. :’)

Link for the harness - Amazon (not a referral link)

Link for the bulbs - Amazon (not a referral link)

Bits and bobs added to my inventory:



Some of you may know of my modest collection of tools and consumables. I buy something if it is required for a job, is reasonably priced and may need it in the future as well. Some things are available cheaper at the neighbourhood hardware store compared to Amazon but during these times, nothing really beats the convenience of having them ordered and delivered at home.

Scissor jack:

VW had bundled this tire jack (not sure if they still do) with the car:

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-24a.jpg

In VW communities and fora, it is also referred to as the widowmaker jack due to the accidents users have faced while jacking up their cars. A classic case of a German, over-engineered product! Ever since I’ve shifted the heavy 3-ton hydraulic jack back to my hometown, I wanted something easier and user-friendly to jack the car for doing the services and odd jobs. I bought this screw jack with the handle from Boodmo which is bundled with many Maruti cars:

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-25.jpg

Simple, works well and is cheap at Rs. 680. Part number for the jack is 89910M75J00 and for the handle is 09824M00017.

Nitrile gloves:

I got hold of a box of nitrile gloves (thanks to the BHPian for the tip for suggesting nitrile over latex) for doing brake jobs and such services. Dirt, rust, oil and such gets into the nails and becomes a pain to clean! Got these from Amazon for Rs. 360 for a box of 100 gloves.

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-26.jpg

It’s a size larger than I would have liked but this would do for now.

Syringe:

When I changed the brake pads last time, there’s a step which involves pushing the pistons on both the calipers to fit the new pads. At this point, some brake fluid overflowed from the inlet of the reservoir. Since I have to remove the rotors for skimming, I’ll end up facing the same situation. I sourced this 50 mL syringe (looks scary!) to suck some fluid from the reservoir before attempting the job. Got this from the Apollo247 app for Rs 42, delivered the same day. Wasn’t available at the local pharmacy outlet (1 Re. coin for reference).

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-27.jpg

Lug wrench extension pipe:

I got myself this GI pipe from a local hardware shop a couple of weeks back - 1 m length, 32 mm outer dia. for Rs. 280. I had to trim the length a bit so it fits perfectly in the boot at the back of the rear seat:

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-bf8d7f19a7f4465397c1e1cd7af99444.jpeg

Man, this thing turned out to be a godsend! Last Sunday, I had to change the tubing of the front windshield washing system and had to access the reservoir which is located in front of the driver-side wheel, hidden by the wheel well lining. Had to remove the wheel to access the lining thus.

The pipe was immensely helpful and I barely had to put any effort to loosen the bolts which were tightened at the wheel balancing/alignment centre. Usually I would have to stand on the lug wrench that came with the car and push/press a couple of times to loosen the bolts. With this pipe inserted over the lug wrench, I just had to push with the hand with almost no effort.

Tightening was easy too although one has to be careful not to strip the threads by over-tightening the bolt/nut as a long pipe exerts a great amount of torque compared to a shorter lug wrench.

This lug wrench extension pipe IMO, is a must-have in any car. Barely takes any space in the boot. Just have it secured using some Velcro belt or something. Easily the best 300 Rs I had spent in recent times.

Fixing the Broken Fuel Cap Tether:



The fuel cap tether broke.

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-28.jpg

I used a coated metal cable (used for cloth hangers) to replace the broken tether with metal crimps on both sides. Drilled a hole on the rotating part of the cap, routed the cable and crimped it on the loop. Drilled another one on the hinge, routed the cable and crimped it on the loop.

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-29.jpg

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-30.jpg

Looks a little crude especially with the bright blue sleeve over the crimps but hey function over form!

re: VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...

Topping up Engine Oil:



If you own a VAG car, you know it is customary to check the engine oil levels from time to time. I measured the engine oil level recently and found it to be on the lower side.

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-1.jpg

Topped it up with the leftover quantity from the 1 litre bottle of Shell Helix Ultra 5W40. This should do until the next service, which is due this August.

Interior Cleaning:



There was dust everywhere inside and I had the perfect opportunity to clean the interiors when I was at the garage, using the HP hose of the air compressor. I conveniently overlooked that part! No access to a 230V socket in the apartment complex makes it all the more harder – no way to connect an electric blower or a vacuum cleaner. The manual way it is then - I used some paint brushes, microfiber towels and some hand-wash liquid diluted in water to clean the plastic trims, the sunvisors, seats and some soiled parts of the headliner. Here are some pics:

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-2.jpg

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-3.jpg

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-4.jpg

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-5.jpg

I must admit the quality of the plastic trims are really good on these Germans - they have held up really well over the years (despite removing and installing some of them so many times) although the upholstery has begun showing its age. For instance, part of it has torn away on the rear seat. Guess I’ll redo the complete upholstery at the 10 year mark. Maybe in a shade of tan. Off white has been a pain to maintain but looks swell when it is clean.

Replacing the front windshield wash tubing:



While using the front windshield wash, some water used to trickle down the bonnet and through the front grill. The spray was also ineffective. Check out these clips:





If the car was being driven, the stray water leaked from the bonnet would spray onto the windshield. This was irritating and embarrassing! I would be engaging the wiper continuously on a bright sunny day until all the stray water was cleared. Clearly there was a leak somewhere in the line inside the bonnet. The last lockdown was the perfect time to fix these minor niggles.

I removed the nozzles from the bonnet and figured out the leak on the co-driver side elbow which connects the nozzle with the stock corrugated tubing. The elbow has a locking mechanism which holds the nozzle in place – undo the black tab and the nozzle comes off.

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-1a.jpg

You can see the scales and deposits from the water on the left one. The co-driver side elbow was much cleaner in comparison and there was no leak. To reconfirm the leak, I tested this elbow at home by connecting it to a 1/4" RO tube outlet and indeed it leaked:

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-2a.jpg

Searched for a replacement elbow from VW’s parts catalog online and it was retailing at Rs 275 per unit (from (Boodmo; no one seems to have ordered this part before as Boodmo shows the snaps of the part on its link if it has been ordered before by a customer) and there were 3 units in this system (one at the pump and one for each nozzle). Part no. 16 in the image below:

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-3.png

This somehow didn’t make sense as it was prone to leakage later. Plus, the car was close to 8 years old. I decided to replace the entire front windshield wash tubing for good. From the reservoir to the nozzles but with no unwanted parts like these elbows. It did seem like a bit of an over-engineered part to me.

The elbow:

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-3a.jpg

Ordered the replacement tubing from Boodmo but opted for a Toyota branded tubing! What do they say? Toyota = reliability? Can this VW have some Toyota love please? Although this isn't the first time, a Toyota part is used in the car though. A Toyota check valve (non-return valve) was installed in the same system sometime back (post from the ownership thread; scroll down a bit). Going by the parts catalog, this tubing is used in a lot of Toyota and Lexus vehicles – Corolla, Fortuner, Land Cruisers, Prius, Camry, Highlander, FJ Cruiser etc.

While at it, I also ordered a pair of new nozzles from Boodmo along with a Y connector to split the main outlet tubing. Cheap anyway. I am a big fan of Boodmo now! I spend a lot of time scouring through their parts for sale, get some info on the part costs, zoom into the pics of the random parts, packaging stickers and get info on the country of origin, batch, year of manufacture etc. Some weird pastime if you ask me!

The Toyota tubing, 3 ft x 2 nos.:

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-4a.jpg

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-5a.jpg

The new nozzles, Y-connector (from Hyundai! Because Maruti had a cheaper part but the cost of shipping was exorbitant!) and a 90-degree elbow (from Aliexpress which was sourced long back for some odd DIY):

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-6.jpg

On a Sunday morn, I carried all the required tools in a bag and drove to my usual place in the apartment complex where there’s plenty of light and fresh air. Could notice the usual morning joggers curiously looking at what is happening! Popped up the bonnet, I removed the old nozzles and clipped the old tubing at the bonnet using a plier. Removing the nozzles is easy – just pull the nozzle from the slot in the bonnet and it comes off. Removed the entire stock tubing and salvaged the stock Y-connector:

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-7.jpg

Inserted the tubing at the 3 ends of the Y connector:

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-8.jpg

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-9.jpg

Carried some hot water in a flask which helps to expand the ends of the tubing a bit. Inserting into the connectors becomes easier that way:

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-10.jpg

Used my trusty ol’ steel cable (there’s some term like snake cable or something which civil construction folks use for pulling the cables through the conduit pipes) for pulling the tubing from one end of the bonnet to the holes:

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-11.jpg

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-12.jpg

Pulled out one end of the tube through the stock rubber grommet:

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-13.jpg

And the other ends of the tubing for both the nozzles:

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-14.jpg

The stock nozzles and the replacements:

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-15.jpg

Inserted the tubing into both the nozzles:

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-16.jpg

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-17.jpg

Took a break and that’s the end of Take 1! Take 2 resumes at the basement of the apartment. A little dark in there but the head-mounted torch helped.

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-18.jpg

While connecting the tubing to the nozzles, I feared if the tubing would take a sharp bend at the nozzles. This would reduce the flow of the water to the nozzles. Luckily, the bend was a smooth one and there were no sharp bends as evident from the snaps (and the spray action):

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-19.jpg

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-20.jpg

To access the wash fluid reservoir, the driver side wheel has to be removed and part of the wheel-well liner has to be removed. Removing the wheel is a pain! Luckily, the lug wrench extension pipe helped. The stock piping was removed from the pump. It has the same elbow at the end with the lock. Inserted the new tubing into the outlet of the pump, connected the check valve and the other end from the tubing to the check valve:

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-21.jpg

The Lockdown Night Ritual:



During this lockdown, I almost ran into a complete battery discharge issue when the car was left unused for a week to 10 days. She cranked only on the third crank. This was scary as I did not have the jump-start cables with me here! To prevent this from happening again, I used to go for a couple of rounds within the apartment complex late in the night, usually midnights. The circuit measures approx. 1.5 km in length.

VW Polo GT TDI ownership log EDIT: 9 years and 178,000 km later...-7.jpg

Got hold of the jump-start cables last weekend when I visited my hometown (1 Re. coin for reference):

A round of professional detailing is due this year and I intend to drop her at DriveClean sometime during October first week before the 8th anniversary. Before that I have to do some paint touch-ups with the OEM touch up kit at a couple of spots and a round of claying.

Before I wrap up the updates, thanks are due to some of them whom I’ve been in touch through WhatsApp and mails for discussing about these issues/updates. In no particular order:

Prithviraj Murali - For all the timely help and inputs man!

Leoshashi – For the feedback on Maruti’s screwjack, for the Zen’s parts and getting in touch with the spare parts dealer. You truly are a lion! Now I need to get the Zen’s registration renewed and get her transported to Gujarat.

ike – For patiently listening to all my rambling! Dude, you really ought to return to Chennai ASAP! I am growing incredibly jealous of you for spending all this time since the lockdown at your hometown.

Paragbhai – For all the inputs especially on the relay harness, the lows and highs of the H4 bulbs , the harness sleeves etc.

espciclo/Fernando – For guiding me on the fault finding part for the high beam issue, the wiring diagrams and the prompt responses over mails. Unfortunately, the Haynes manual for the Polo 6R doesn’t have the wiring diagrams for the single barrel headlights and neither could I find one at the Elsawin website when I had downloaded the entire contents for the repair of Polo 6R.

Jayaprakash/JP – For resolving the high beam issue, the replacement of steering rack and front strut bushes and bearings and, the quick turnaround time after dropping the car at your garage.

Pending works:



1. Skimming front brake rotors.
2. Fixing the wiring mess at the interior cabin light area (too many consumers tapping +12V from the cabin light and all the wiring going haywire).

I like the fact that this car has become a proper study tool over the years - there’s just something or the other to tinker around during the weekends which otherwise I’d spend binging some serial. I have learnt so much and continue to do so every time I fiddle with her. What I really miss at the moment is DRIVING! I terribly miss driving to my hometown, to Yercaud - the hill-station at our backyard where we’ve spent several weekends, to random places on account of colleagues’ engagements, weddings and receptions. Sigh! The current covid scene and the soaring fuel prices have made it really worse for some of us. One can hope the covid scene would die down shortly but I am not sure of the other. Anyways, thanks for reading guys. Stay safe!

It looks like my luck has run out. A little birdie told me my office might start functioning in September. I'd rather have a colonoscopy than come back to Chennai again.

Seems to be an issue with battery or current leakage.

In my Vento TDI, I have not used for 30 days at a stretch, it still starts with a single crank.

Do get it checked. If battery is up for replacement, got for Amaron.

...What I did four years ago. And am going to do again tomorrow!

Took the car out today, 8km. Wasn't quite satisfied with my my parking. Couldn't even turn the engine over! When we came to go home, about three hours later, it would start, and it seemed fine when we got home. But I've learned my lesson about battery-replacement warnings, and not trying to get just a bit more time out of it.

It used to turn so many heads when the coming-home and leaving-home lights would turn on at the parking. But as they say, all good things must come to an end and thus, I chose to gracefully retire the bi-xenon setup.

So what went wrong really?

1. The Morimoto ballast on my setup had the output AC cable permanently connected to the ballast.

The later units from Morimoto came with removable input and output connectors for the ballast like this:

2. The Aliexpress’ straight D2S igniter cable failed to work properly. Guess one can only expect so much from a cheap cable.

Is there any way I can reuse the bi-xenon headlight assembly? Yes, with a new ballast unit. I’ll save it for later in case I change my mind. Unlikely but still an option. The headlight assembles were safely packed in the boxes. Never going to part with those and maybe, just maybe, I will fix them up some day. :’)

So what next? I had to invest in a new set of headlamps.
I am very sorry to hear the headlamp saga. We both are in same boat. The straight connectors I bought from Morimoto india and the Ballast gave up on me as well, on a trip to Calicut. At night the high beam cut off with the intermittent working/non working state. It started with the right bulb, then flickering on the left side and eventually both high beams went out. It would work some times and gradually the headlights failed. I tried to troubleshoot it from the Hotel basement (where I was staying) and messed up the bulbs. I shouldn't have attempted it in hindsight. I also had a tough time sourcing new bulbs.

I had used these headlights a lot and given the covid situation and a new place, I had to go for a replacement set of headlights. Just like you, they are packed safely and I hope to revive them soon. I am also considering LED options though.

The aliexpress straight connectors are definitely bad, not going to last the time. First of all they are not easy to fix, and secondly they don't connect up to the bulb well. I suspected a loose connection first, but it looks like the poor connections messed up the wiring over a period of time.

Just like you, I miss the nice sharp cut off. A lot of people loved the cut off with blue hue. Together with the XP micros (which are still holding up well btw) were damn good for night drives.

Anyways, moving on to the updates in no particular order.
Excellent set of updates Gannu. Thanks for the same. Nothing like a VAG car to teach you a lot of stuff. And some serious time invested too!

The headlamp heating is going to happen when you use the uprated bulbs. I don't think that it would be a major issue for the plastic lens. Perhaps some dulling in the long term. However I have heard of folks using ceramic holders to counter the heat buildup at the connector. I found it is it was more of an issue if you were constantly on high beam and switching constantly between high and low. Personally I used it on my 800 years ago but it was a disappointing affair resulting in a short due to low quality workmanship. Never went down that path since. Quite a popular upgrade though.

One suggestion on my part would be to invest in a torque wrench to help you with the lug nuts in place of the breaker bar. It provides the necessary leverage and you can ensure proper torque while tightening. For loosening you can set the torque higher and get it loosened. I never let the gun be used on for tightening lug nuts at alignment centers I frequent. The final humiliation is me offering to tighten it myself after balancing etc. They can never live that down!

Drive on,
Shibu.

Nice update. You car looks immaculate (inside out) for having run so many kms.
How is Bilstein holding up after running 80k+ kms?

Gannu!It was an absolute pleasure to meet you at the garage. I always wanted to bump into you and check out all the mods you have done. Unfortunately, the pandemic ruined it this time!

I was surprised that you changed to the single barrel setup and had come all the way to Perambur for a high beam issue. Didn't realise there was such a huge back story!

Interested at the rate you got the single barrel headlamps for. Looking to replace ours shortly.

Ours is completely cracked up and yellowed, as you would have seen. We had used 90/100 bulbs with relay for a year after which the relay failed(Finolex/Lucas branded one, the Phillips were out of stuck back then). Currently we're using those high performance 55/60W bulbs from Osram. It's been almost 2 years.

Also surprised at the variation of part life in the same type of cars- your steering rack has effectively lasted twice as much as ours while we're still on the stock Gabriel shock absorbers at 1.1 lakh kms.

Wishing you many more happy miles with that much loved machine

I'm sorry if you had mentioned it earlier but since I have started following this thread now only, let me ask you this :

In your 7 years of ownership, have you ever re-painted/wrapped or did any custom work to the paint? As the black still looks really amazing and glossy!

If it's still the stock paint, VW's paint quality is exceptionally good and may I please know how do you maintain your cars beauty(external) throughout these years without getting the paint faded/visible scratches/rust etc?

Thanks!
