Evening all, Car = 2004 A3, 2.0 Tdi 140, DSG (BKD engine) on around 91k miles The car runs very smooth and produces good power from tickover to around 4k. The problem I have is when the engine is warm (anything above 70degrees approx) but especially when the engine has been running for a long time (20 mins plus) when the car is put into either neutral or park, there wil be a strong vibation/juddering on idle. It is so strong that even passengers have commented on it. This does not happen when the engine is cold and also stops IMMEDIATELY as soon as the car is put into Drive or Reverse. No funny noises and seems to drive fine upto speeds of well in excess of 100mph with no other issues. (I travel to Germany every few months) Any ideas?
