I'm not sure if this problem is widespread or not, but ever since last night, my car has been slow on the pickup... I mean, the car used to pick up like it was light as air.. now its stuggling to get upto speed. I can't think of anything that I did to cause it... maybe its a faulty/dirty fuel injector... I'm takin it to the dealer tomorrow to have them check that out. The only thing that could have been iffy is when some a**h***e in an A8 tried to race me at a light... needless to say, he was multiple car lengths behind me when I checked my mirror... do u think I could have f-ed something up???

 

sounds like you went into limp mode - I believe there is a TSB for this. Check the TSB stickies at the top of the 5th gen forum.
