It's not something that is reproducible on demand, so giving them the car and telling them something happens that they can't reproduce... it's frustrating for them, but more so for the guy that gets the answer 'we can't fix that,' each time I report it as a problem. This thread helped them point to the 'comfort mode' as the resolution since dynamic can be a bit rougher. That CANT be the solution, and I know it still does it in comfort, but who the hell drives it in comfort?

There has to be a centralized audi db where these issues are collected. Even if its only 10-15 people that have reported it, and someone has documented a fix, I can't imagine that audi does not have the ability to check to see if others have experienced the issue.

So, after a week at the shop (nearly) I'll be going to pick up my car with, jerky transmissions (occasionally from 3rd to 2nd or 2nd to first), a software update that removes my HD Radio (as a solution to the poor quality) but fixes other issues that needed fixing, as well as a new front plate insert that was pealing, and another un-diagnosed issue: car taking a while to turn over, or doesn't start on first try.

oh well. might be back to lexus for my wife's next car--the guys are audi are nice, but seems like the corporate audi overlords are a bit too stingy with allowing fixes or something.

I had more issues with it under hard driving sport mode, it revs and the gear kicks in just as I had the gear in Neutral rev and snapped into a "D", the car will try to go forward with my rev force but the tranny stops it from doing that. I experienced it about 10 or more times, I actually looked back to see if someone hit me from behind.

After multiple visits to a Dealership, TCM reprograms and such, my car is acting even worse, they are changing a part called Transmission Valve Cover, I will post again to see if that fixed the problem, they said only thing left to do after the change is, replacing the Tranny.

I only get the jerk when I'm driving less responsibly then go back to driving normally (the mode I'm in doesn't matter). The transmission is behaving as if I'm, still going to or want to, drive with more aggressiveness; the jerk is the transmission "resetting" itself.

Once I noticed it, I changed my driving habits, now it happens very very rarely. Since the sport diff is software controlled I believe a really good update should do the trick, if its available.
