Just bought a late 2005 b7 a4 2.0tdi S line 140. Car drives very well, accelerates pretty good to. HOWEVER... 1. When put into high gear and in low revs the car judders violently until about 2k revs and then just accelerates normally. When the car is in 6th gear at around 1200-1300 revs upon acceleration it shakes quite bad. This then stops at 2k revs and the car drives normally. 2. At idle the car also shakes a little. I have had one of these before with an oil pump issue so know what thats like - my last one would shake and judder hard on acceleration no matter the position of rev counter. This car however is smooth high in the revs and will easily go over 80mph! What do you guys think it is? Quite worried. Any help much appreciated Thanks in Advance!
