I have an Audi A6 prestige 2015 and my car shakes when not moving. The car drives perfectly. I brought it to the Audi and they checked the coil but the coil were good. Then the said that are the fuel injectors, they fixed it but, the car still with same problem.

I don’t know how bad the shake is. But have you checked the motor mounts?

i really don’t know if they check the motor mounts but, i Audi changed a year ago the motor mounts.
