VW Denmark is not budging in DSG7 problems

In the last few months, some major media, here in Denmark, reported on DSG7 problems, and had interviews with PR-reps from VW Denmark. VW Denmark is not budging in DSG7 problems. Journalists were mostly asking same questions, and getting the same answers. Or, perhaps VW Denmark only answered on selected questions.

But, common theme in the articles were mostly asking, if VW thinks they have general problems with DSG7 transmission (internally known as DQ200). They of course answered with “no”. Volkswagen is claiming that they know about very few cases with problems, and that these were taken care of, either under warranty or ex-gratia, where consumers were asked to pay a part of the repair.

Another common theme in the VW answers were, indirect blame of the consumer for the problems. Declining to acknowledge the problems and responsibility, VW is automatically blaming consumer for the problems. They even used numbers to deflect the blame, and informed  journalists they sold 8.500 cars with DSG7 transmission, out of those VW claimed “only” 311 had problems. This is a 3,66% error margin, if we are just to take look at their numbers. Which I am not completely confident that the numbers are true. Even if the numbers are true, there is a question about what models it was sold with.

There are some models and engines more suitable for DSG7 specifications, and others are less suitable. Eg. engine torque, and the size/weight of the car.

An example to illustrate the issue

Another example of this (bad engine combinations) could be following;

DSG7 is rated at max. output of 250 Nm of torque.

  • Polo 1.2 TSI 90-105 BHP has about 160 – 175 Nm of torque
  • Touran 1.6 TDI with 105 BHP has 250 Nm of torque.

As you can see… Touran with TDI engines is riding on the limits of the DSG7 gearbox specifications. And this is only asking for troubles. That VW went anyway with this combination of engine and gearbox is beyond my understanding.

And consumers are to be blamed and pay for their design/manufacturing flaws?

So, now if I could only get VW of publicising the numbers of sold Polo’s and other models well within limitations of the DSG7 gearbox, and deduct that number from those 8.500, I am pretty sure error rate will be a lot higher, than 3.66%.

Comparing the components…

So I got a hold of a component ID’s from a Golf 2013 model, and compared it to my car logs from 08/2011.

Bold = identical
Red = older
Green = newer

Both gearboxes are identical, as they have the same hardware ID. Software is only minor revision compared to mine. Revision line is different but I am not sure what is this covering. Maybe somebody else can shine some light on this.

So all in all, if VW is claiming that they have built new revised gearbox, I don’t see it here, as the Hardware should have changed as well? I think they just adjusted the software to make the shifting a bit faster, and at higher RPM’s. Which results in higher fuel consumption, than advertised. And yes, I know that fuel consumption is already lower than advertised, I mean, even lower… And they still can’t provide definitive proof that this even works. Because it does not work on my gearbox.

Dear Volkswagen, stop lying to your customers!
