Hi guys,
I have an Audi A3 8P, 2008 with a 2.0 diesel engine (CBAB) and DSG transmission (LQV). I am experiencing a few issues with the front axle / transmission / engine mounts and I would need your help to identify the cause, likely multiple causes. Symptoms are:
road noise in between 40-50mph and around 70mph (suspect wheel bearing)
shaking under hard acceleration - most noticeable when engine rpm is under 2000 (suspect engine mount)
DSG clunking when breaking and accelerating again
I suspected the shaking might be caused by the lower engine mount so I lifted the car up on stands to check. It does not seem like excessive play to me but honestly I don't have much of a clue about how it should behave. The video below shows the engine start, then I put it into gear and there is some stuttering because of the ASR, and later I switch ASR off and try accelerating again. You will be able to hear a clunking sound which appears to be coming from the DSG. A similar clunking I hear in traffic when for example I have to press the brake lightly, then I go back to accelerating.
Hopefully this video will help you help me. Thank you!
