Hi, 1st post. Owned an A6 1.8T quattro for a couple of days now, lovely car in metallic green (nil leather though!). Took her out for a spin today, and found it to be very hesitant on accelleration, as if it was holding back?? It's still under what warranty the garage gave me but I'd like a few ideas first. Would it be worth popping her on a rolling road? Or is there some thing that is common that would cause this? Cheers for any future help.
