Heres a tricky one my 3.0 multitronic is smooth as anything except for a strange coarseness / vibration through the steering wheel which happens when accelerating through 1800 and 2100 rpm in auto mode or in numbers 2 to 6 of the manual gears, (dont feel it in first for some reason). It is also present, although much less noticeable, when decelerating through the same rev band. It is also more noticeable when holding the bottom of the steering wheel. I have 18 wheels with 235/40 Pirelli P Zero and Michelin Pilot tyres and did put the vibration down to poor absorption of road surfaces for a while but after much trial and error have isolated the feeling to these revs rather than speed or anything thats happening on the road. It does not seem to make any difference whether the wheels are straight or turned. My cars done 47k and has the multitronic oil changed in the last 2k. Is this coarseness / vibration yet another multitronic quirk or could it be something else? Advice please!
