Default Re: VW Polo - Maintenance and Service cost and dos/don'ts

The VW Kolkata service centre takes my car up by a lift and that is the last I see of my vehicle. Come 6.30/ 7.00 pm my car is brought down and I am presented with a Bill. Whether brakes are cleaned or not is debatable. The oil is new as seen on the dipstick, the filter is new and the washer fluid is full. The only thing that was done in front of me when my car was brought down was AC disinfectant with a foamy spray the scent of which by the way lasts only till the next day.

The items shouold be listed clearly in the service booklet.

For that price, you can get the brake discs skimmed on a lathe at an FNG. What a ripoff!
I think I fell for this one last year, but not this. They seem to have become another retailer of 3M treatments, and, unless one says a specific no, they will do the lot. Makes me wonder how much time and attention they give to the engine and mechanics, which is what the car is there for!

If one wants 3M treatments, then it's all good: one-stop shop. The thing is not to be caught out.

So far as the air-vent thing is concerned, if the ventilation system is to be disinfected, shouldn't the compound be sprayed into the venilation air intake? I cannot see it doing much other than smelling a bit, if sprayed into the outlet.

Thanks Gannu. Would try to answer to your respond to your questions and provide some additional info.
AFAIK he wasnt experiencing anything, however now since the SA told him his brakes need to be checked he has been a bit more careful, but no juddering. Does anyone know any local FNG shop? He stays in Andheri E.

He wrote a mail to VW downtown and got a call from some Mr. Pujary who acknowledged him and told his assistant (who connected the call) that to send all the details of the servicing which is done at 45k interval to my friend. He also asked his assistant to take out the job card of the servicing done (but since then nothing). When my friend told him that he was there throughout the servicing and brake pad cleaning and Ac disinfectant was never done, he just said OK, and nothing after that.

Should he go to VW Downtown to get his brakes changed or get it done outside? If so, any references would be very helpful.

Appreciate all the help.

Default Re: VW Polo - Maintenance and Service cost and dos/don'ts

i have a peculiar problem in my vw polo GT 1.6 tdi,

-->>after i received my car (12000kms run) back from service,i felt loss in power and turbo didnt activate,i gave car back to authorised service guys,
they did detect as g31 pressure sensor wiring harness problem and replaced it in warranty,

even though, i did find characteristics of the turbo range are changed(no error code though),i am finding acceleration is more towards linear side now rather than the wilder push which used to be earlier,
i did check whether new software is updated which makes the car more tamed;
i did cross-check myself, its still running on old 2013 software not new 2015 software,i wish my car could go wild as earlier,i wish i could find my answers in this forum

regards&thanks in advance

Can you hook the car onto the VCDS/ OBD reader and let us know what is the boost the Turbo is developing at its peak range?

I guess the turbo plumbing leakage. Check all plumbing once.

Well,i don't have VCDS cable, I need to go to authorised service center for that.

On a blunt note I can say that earlier the turbo spool was around from rpm 1200-2400 which was more punchier with push back in the seats. Right now the turbo spool is from rpm 1800-2600, but no push back in to seat effect, but more linear in nature. Seems like there is leakage in plumbing.

Mod note: Please start your sentences with capital letters. Thanks

Even I'm feeling a loss of turbo especially when shifting from 1st to 2nd and 2nd to 3rd gear. Also, a noticeable loss of power when the A/C is switched on. The service center guy said no issues as there were no error codes.

Will leave the car for thorough checkup this weekend.

I can relate to your problem.
Did your car ever go in a limp mode i.e can not go over 60 kmph in any gear at full throttle??
Did you ever see glow plug indicator blinking on dash while driving??

What is g31 sensor---
It is also called Charge Air Pressure Sensor G31


what the use of it??
The air pressure in the intake manifold is determined from the Charge Air Pressure Sensor G31 signal. Engine Control Module (ECM) needs the signal to control the boost pressure.


What happens when g31 sensor or g31 cable fails??
If the Charge Air Pressure Sensor G31 signal fails, there is no substitute function. The boost pressure control is disengaged and the engine power decreases significantly.

Coming to my story--earlier this month i felt loss of turbo power and authorised service diagnosed g31 sensor wire problem on my second visit to them on same problem.They replaced g31 sensor wire,but if it is sensor wire/sensor problem,it will show up on the computer via bosch cable which vw service guys use.
One a side note g31 sensor/cable problem is an issue with all 1.6 tdi engine across vw,that is what i was told by service mechanic at authorised service center.

I suggest you to check the computer screen yourself while they are doing diagnostics,they did not acknowledge the problem during my first visit,second time when i was at the service bay looking at diagnostic screen with out blinking my eye,they did acknowledge finally and replaced


I did test my polo 1.6 gt tdi today on our private layout road with no traffic,here are my observations :-

--turbo spools from 1800 rpm and it evens out at 2600 rpm(before servicing it was punchier than now)
--not exciting between 3000 rpm to 4000 rpm(earlier there was no need to rev in this rpm range)
--when clutch is pressed at 4000 rpm,it takes less than a second for the rpm needle to fallout at 1000-1200 rpm from 4000 rpm(earlier never noticed this phenomenon as i was excited about its torque)
--3rd gear at around 3400 rpm reached 85 kmph (earlier it was around 105 for the same rpm in the same gear)
--vehicle did pull with not much effort from 40 kmph in 4th gear
--did not test in 5th gear
--inspite of this,car delivered 13.6 kmpl (earlier it was 15 kmpl,it was a base level after driving 2 kms and climbed to 17-20 kmpl on avg in sedate driving at 100 kmph)
{earlier i achieved 22-24 kmpl at 70-80 kmph in 5th gear at a 5 kms stretch}

I request polo tdi owners to suggest independent garages who are expert with these engines and are enabled with vcds cable in hyderabad area.
I heard vagtune opened their shop in hyderabad,if anybody would confirm it ,that would be great.My car is in warranty but as the authorised service people are incompetent and they fail to acknowledge the problem.I wish to give a try on independent garages

for the long post and I just bought 'Team-BHP Sticker Set' on Team-BHP
Disclaimer- all my observation are not accurate due to human error and done in safety conditions on a private road with no traffic/pedestrians.

I had glow plug warning in December due to rat bites which the vw service technicians fixed. Since, there are no error codes, I'm suspecting a mechanical fault.

It's driving me crazy that I can feel something is wrong and no one else can. One of those days where I deliberately want something to be broken in my car

Mine is a 1.6 GT TDI. They had repaired the wires. It cost me around 4k. The bill is at home. Will check and update here. Will definitely get the car checked thoroughly.

Hey,
Check Engine light started flashing on my 1.2 TDI(104000km) since yesterday. Hooked it up to OBD and error code p0405 showed up. Googled for the same and got 'Exhaust Gas Recirculation Sensor A Circuit Low'.
Has anyone else faced the same error code?. Please enlighten me on this issue.

Code P0405 means that the EGR Valve Position Sensor is giving low voltage readings that are usually below *the .5 - 1.0 voltage range.*

Check the voltage at the EGR sensor and also check if there is a problem in its opening /closing. IMO get it cleaned once.

Check the wiring once.
