All,

As I mentioned, they showed me black fluid coming out of the fuel filter when they cleaned it and I asked them to replace the fuel filter instead of cleaning it (as it is no more replaced in regular service as per the SA!). They also sold me a fuel additive that helps clean the fuel filter, injectors, etc (they could not explain to me how it actually works). It's been 9 days since this service center visit (DSG upgrade + new fuel filter), the shuddering gradually reduced over these 9 days. On Saturday, I refilled the tank with regular petrol but poured this additive before refilling. Since then I did a 250 km trip to Nagar and then another 70 odd km in Pune city traffic. On the same speed-breakers I see no shuddering over last 2 days. There is mild shudder at times when picking up speed and going from D2 to D3 but that's mild and now happens say 3 out to 10 times, which is much lesser than before. Will continue to monitor and report in another week.

So looks like clogged fuel filter was the culprit. Do change your fuel filter and see if it helps.

Cheers!

So, I had sent the car back to the service station. They couldn't figure out what the issue was initially, called me in for a test drive again with the technician. They tried all sorts of upgrades and resets but nothing solved the problem. They were reporting all of this to VW over mail. I was given my car today after 4 days with the same problem and a bottle of additive as discussed above. I have put it in the fuel tank after getting it fuel. I have been told that due to poor quality of fuel in India this problem has happened and this additive will help clean the system. I was also advised to use this at every service interval. I am now waiting for results. I hope it gets better.

Also, I have been having this issue where sometimes when the car shudders and I try to accelerate, suddenly the EPC and ESP lights appear on and I am not able to drive. I have to switch off the car and start again, and it works perfectly. I thought this issue was resolved when I sent the car for service last week, but it happened again today. Will wait for a few days to see the results. :Frustrati

Watching your video made me feel like i was hearing an echo of my thoughts each time i got behind the wheel of my ex GT TSI over the three years that i had owned it before i sold it and bought the Abarth Punto. The sheer effortless way it delivers power to its wheels thanks to the DSG is just pure magic that cannot be explained but only experienced. If theres one car that i want to purchase all over again it would be the GT TSI clap:

Any other changes seen apart from 16" wheels in MY 2017 GT TSI?

I am planning to book one for my wife and I am wondering if I should wait for some more time

If you can access a Vcds cable and emulate the same while logging, then nothing like it.
That will give you an exact idea.. To do an auto scan before and after the incident will also give you clues as to which sensor has gone kaput.
Also, make sure you don't have any rat bites on any of your wiring harness. Have your car checked for any rodent tell tale signs.

Dear All,

I would like to thank everybody in the forum for providing vast amount of knowledge and sharing experience which has helped me to decide on Polo GT TSI. I have probably read most of the concerned posts but there are two questions which makes me re-think about investing in this car:

1. Is DSG reliable enough for our country with 91 octane fuel as 97 is very difficult to procure? Shuddering seems to be the common issue. I'm planning to use this car approximately 6,000 to 7,000 KMs a year including mix of city driving on weekends and long trips to holidays (mostly in himalayas). I will be going for 2 year extended warranty and have been told by SA that extended warranty covers the gear box.

2. What fuel other members have been using? VW recommends 95 RON which is not available at-least in Delhi-NCR. Can somebody guide on this?

The engine works fine with the regular 91 octane petrol. There is no need to worry about sourcing 97 octane petrol.

Jerking while changing from 3rd to 2nd gear is a common behavior with the gearbox. However, the latest software update to the DSG has greatly reduced this jerk. I have experienced this and many others have confirmed this as well.

Regarding reliability, though VW claims they have sorted out all the issues, the long term reliability will be known only after two more years. Having said that if you take the 2 year extended warranty, you should not worry. VW honors warranty on the DSG. You need only to be prepared for the inconvenience while the car is in their workshop for the replacement. If you are fine with that small risk, then go ahead. The risk is worth to take for the fun you would get with the 1.2TSi + DSG combo.

Thanks for the info and confirmation. Another thing that is being talked about is Synthetic vs Mineral Oil for the DSG? What is your's and other's view on the same? Is their any way to check what Oil has been put in a new car during the PDI?

VW has switched to mineral oil for GB about 2 years back. No need to check.

97 octane petrol is indeed available in Delhi, for instance at BPCL at GK-1. As for what type of oil is in the gearbox of a new car from factory there is nothing for you to worry about- it will come with company recommended oil for that particular gearbox. It is not something you and I can top up, so we can even remain blisfully unaware. Especially for the DSG gearbox it is best to leave it to company authorised service centre. On the other hand my other car - a Hyundai - runs much smoother on synthetic oil than mineral. Actual oil selection and filling was done at ASS.

Ive tried regular 91, speed and speed 97. Works fine with all of them, and personally i have not found any advantage with 97 over regular fuel.

As freedom pointed out, switching to mineral oil was one of the fixes VW did for their earlier DSG issues. They even recalled cars and changed the oil to mineral. All new cars come with mineral oil and there is no need to worry about that.

The vehicle needs to have an engine capable of utilising the extra octanes from the higher rating fuel, the 1.2 is too small an engine to show any marked improvement.
Fill 97 RON in an Octavia equipped with the 1.8Tsi and see the World whizz by at alarming rates.

Car feels much more light on 93/97 than 91. It does make a bit more power as the recommended Ron is 95. Now if it's worth the extra 17 rupees is upto the buyer

Try it for a few tankfuls. Only then will you notice the changes.
