Hi,
I recently bought 2008 Audi A3 4-cyl. 2.0l/125kW 16V TDI with automatic transmission. Engine code: BMN, transmission: KMW.
Sometimes after startup whole car shakes/vibrates in parking mode, but sometimes everything is fine. It can be felt through driver and passenger seat.
Earlier this day I got it checked with VCDS, no fault codes detected, rpms@800-820 (at idle), all 4 cylinders fine. But when it does happen, only by applying revs to rpms@1800 shaking disappeared, but after removing pressure form gas pedal and letting rpms drop down, same thing happens. After driving it for 15 min everything seemed to be fine. When I bought it from owner, he said he changed flywheel, before listing it on sale.
There is a time when after start everything is fine, no shaking at all, but after giving it some revs only when revs dropping down hits somewhere rpms@900 it shakes for very small amount of time and when reaches rpms@800 is working fine without shaking/vibrating.
I hope someone can understand this and give a hint or possible solution/cause. It is pretty hard for me to explain, but I hope for the best.
*EDIT*
Forgot to mention that DPF has been removed.
