Hi,
I've read your opinions on this, and I think it's absolutely great that you've written to me about it.
That's what we're here for. However, your case isn't a typical one or one that can be easily found using the search function (from now on, it will be

).
What you've written here, no one at VW could confirm, which is quite sad.
We've noticed this before. It's mostly generic stuff, with not much substance or depth behind it.
The best thing would be to figure out exactly how the Bosch workshop did it... that would be ideal. However, they haven't commented to this day on how they actually adjusted it.
When did the incident occur? Since some time ago (January 2002), the burden of proof has been reversed, meaning that it's not up to you to prove something, but rather they have to prove that they did nothing wrong (at least during the first six months after the repair).
That's already an indication that you're hiding something.
At the very least, it sounds untrustworthy.
..I'll figure it out, someone was responsible, and they'll pay for it...
I'm rooting for you.
Teach us about the result.
Okay Bertil, thank you for your comments

...this has been going on since April 2002, and the car has been sitting there since July 11, 2002...and it's not just that the engine is broken and needs to be replaced...but also the compensation, I had the car in a workshop in Aachen, but I'm from southern Germany, 40 km south of Ulm...all the transportation costs for the inspection, etc....I could have already bought a good engine for that amount

...I'm very confident.
