Update @ 75,000 kms on the ODO:

Recently I had a funny (?) problem with the Jetta. Normally, Idle RPM settles at around 800. But a month back, suddenly it started misbehaving..

That is, the idle RPM used to jump to 1050 randomly and stay there for about 15 minutes and then come down to 800 RPM by itself. This problem was irrespective of whether the engine temperature was just warm or optimum, and it used to happen once or even twice every day.

When I googled for a solution, I came across lot of incidents with similar issues. Most were pointing towards either the Battery or the Alternator in general. I had replaced the Battery recently, but it can't be ruled out as it could be a prematured failure.

When I performed an AutoRun on the VCDS, result was interesting. It said that there was intermittent open circuit in the Drive Battery voltage.

By now I had got the Battery checked and therefore thought that the problem was with the Alternator. Car was in extended warranty, therefore no issues. I took an appointment with the Mysore Dealer and took the car to the service station, when I was in Mysore for some other work.



Battery, Alternator, cabling were throughly checked and found to be fine. I was asked to use the car for 15 days and get back if there is any problem.

Since I drive a lot in remote areas, I insisted on checking the under-chassis for any issues. While they were checking, it was found that the drive belt (which drives the Alternator) had become brittle and had developed cracks. This usually needs to be replaced at 90k Kms / as required.

I didn't want to take a chance and asked then to replace the drive-belt. This costed me about Rs.1000/-, labor was free as the car was in warranty.

After that, I have driven the car for about 1000 Kms / 15 days. No problem what-so-ever. The idle RPM is latched at 800 all the time whenever the engine is at idle.

Other than this incident, the car is running like a charm!

I will have to replace the tyres in about 5,000 Kms. I am very much satisfied with PS3. But I am also thinking about P3ST and CPC5. Suggestions would be immensely appreciated.. Please!

I switched to the Pilots sports 3 some 1000 kilometres back and am happy as heck with it, just as you are. The Conti's are a good option, but don't go with the primacy 3 st, it's a step backwards compared to the pilot sports. My 2 cents are that you should stick with the Michelin's you currently have, either in the stock size or in 225's.

I used the Primacy3ST (205/55R16) for about 1200 kms before switching to Pilot Sport3ST(225/50R16). Ride being the Jetta 2.0 TDi DSG.

While the P3ST were very comfortable and silent, they were giving me a disconnected feel on curves and bends. It was as if I was floating on a cloud and this made me uncomfortable to take curves without slowing down drastically.

Now having driven the PS3 for approx 500kms, I believe I have made the right move. The tyres grip like leeches & are even more silent than the P3ST. They do seem just a bit harder when going over broken surfaces at low speeds. The speeds that I can now carry into and out of the curves are quite scary, tempting but scary.

I have been forwarned by the tyre seller and couple of people using this tyre that it will wear out between 35 & 40000 kms and at nearly 60% more expensive than the P3ST rated at 45000+ kms, these are an expensive yet enjoyable proposition.

It used to happen in my Laura TDI DSG. What I concluded at that time was, the dpf kicking in.

Usually it would happen after my journey is complete and sometimes randomly at traffic stops too.

Recently I had a Octavia TDI as a loaner with me and it did the same thing at some traffic stops. Revving the engine a bit would make the idle rpm drop to 800.

Yes timing belt needs to be replaced in 5 years or 90K kms. Don't know how that can cause rpm fluctuation though.

It was not the timing belt that was replaced. It was the Drive belt. A drive belt connects the engine and the alternator and drives the alternator at a given ratio..

Since this belt was brittle and slipping, the alternator was not delivering the required charging voltage to the battery. Once the ecu senses the lower voltage, it increases engine rpm to compensate for the loss. 😊

Congratulations for the charming (fill it forget it kind) machine. Many of us went for remap totally based on your unbiased review of petes and we owe a lot to you.

regarding tyre, you have reached the extreme in terms of performance. Looking at your usage, i believe the car is mostly a highway cruiser and you dont push every now and then in the corner. I installed P3ST 4500 kms before and i am completely happy with the performance. Looking at the experiences in my friend circle for michelin P3ST it should last atleast 50000 if standard rotation practices are followed. CPC5 may be grippier, but nothing beats silence that michelins can provide.

Thanks. My thoughts are the same.. It is either PS3 or the Conti's.

PS3 is noisy after 20k Kms, even though the tyre millage is about 40k Kms. The last 20k Kms will be very noisy, even though the grip is good. Last 10K Kms, is worse, we can literally feel the hardness in the rubber.

Any idea about Conti MC5 ? They are rated above CPC5. The side walls are also better.

Thanks! PS3 has been great for me except for the noise after 20K Kms.. Was just thinking about options, if any. 40K Kms mileage is good enough for me. I don't expect better than that.

Thanks! Good to know that I was of some help.

I've heard good things about them, even debated getting them instead of the Pilot Sports 3, but didn't know much about them hence stayed with the tried, tested and trusted.

This thread talks of them. The positives seem much the same as the PS3's; improved steering feel, good comfort, minimal noise, excellent performance and grip. Seems like a solid choice to make, all things considered.

Interesting to note that both are almost neck-to-neck..

MC5 is almost 2K / tyre cheaper..

I have used P3ST in the Jetta and MC5 in the Polo GT TSi. Both offer a very good balance between comfort and performance. I find them very similar. On the other hand, PS3 is purely performance oriented and would be definitely a lot better than P3ST and MC5 in terms of grip. So if comfort is your preference, go for P3ST or MC5. If performance is your preference stick to Pilot Sport 3 ST.

Note: My opinion on PS3 is just from the reviews that I have read in this forum and others. I have not experienced it, yet.

On a side note, the P3STs in the Jetta have now done 36K KMs and have become hard. Road noise has increased a lot and there is wheel spin when pushed hard. I also see some small cracks on the tire surface. I am going to change to 225/50/R16 Pilot Sport 3ST either by the end of this week or early next week.

EDIT: I believe P3ST and Max Contact MC5 are comfort tires, and Pilot Sport and Sports Contact 5 are performance tires.

EDIT2: In the tire comparison you have listed, though the numbers are close, PS3 fares well in terms of dry grip, wet grip, road feedback and handling, whereas MC5 fares well in comfort and wear. Do a comparision between P3ST/MC5 and PS3/SC5 and see if the numbers match closer.

Thanks Ganesh!

What price are you getting PS3?

P3ST & MC5







PS3 & CSC5





I think, PS3 stands ahead. Also, CSC5 is not available for R16 rims.

When I was inquiring on the availability a few months back (when the PS3 ST was introduced), I was quoted 12.5K per tire. I need to check what the latest rates are. I will update when I get the tires changed early next week.

+1. I think PS3 is the obvious choice here

Indeed 12.5k is the current rate for it here in Mumbai, Bhpian iliketurtles got his couple of weeks back, No doubt PS3 comes out on top and if i plan to swap my tyres too in a couple of weeks its going to be the PS3's only.

PS3 is the best no doubt! When it comes to the grip, it is the king here.

Only thing is that it gets hard and noisy after 25k kms. That is making me look at MC5.

I will wait for your feedback as you would have checked all three of them..

Hi,
I own a 2012 December Jetta. I was looking for help on buying wipers for it. Can you please let me know the specs and where I can buy these either online or offline in bangalore?
I dont want to buy the VW OEM wipers as I believe they are ripping me off charging 3k for it.

Appreciate your help!
