Hi all I have a4 B9 year 2016 with S tronic gearbox (dl501). First 30 minutes of driving car vibrates while it is stationary (foot is on a brake pedal) on D and R. N and P is silky smooth. After cca 30 minutes car is no more vibrating and everything is fine. Gearbox shifts ok right after start. There is no extra sound when it is vibrating. I have brand new engine mounts. Car has 140 000 km. Last oil change was done at 120 000km.
What could cause this problem?
Thanks for help

 

I have the same problem on A4 avant 2018.
Strong vibration on waiting at red light with foot on brake but if I put it in N car stops vibrating.
