Hello all. This post probably belongs on an Audi forum, but I'm not a member of any and quite simply just like rennlisters better. I have a 2010 Audi S4 (dual clutch trans) with around 95k miles. The car has developed an interesting vibration under acceleration - I notice it the most at full throttle, towards the top of 3rd/4th gear. Higher in revs, more vibration. Mostly noticeable through steering wheel, but can also feel it in the seat/centre of car. ONLY happens when accelerating, not when cruising (no matter what speed). Any ideas? Car has new tires, fresh alignment, lots of new bushings. Not sure where to start.
