I have a vibration when the car is parked when I slowly accelerate. As the RPM slowly climbs around 1800 the car will vibrate and till it hits 2200 and stop but at 2800 it will come back. If the car was driven at stop and go condition the feeling is sluggish and the feeling is like the car is just abmormal.

The dealer has checked the car for 3 weeks now and said the AMG cars has its own characteristis and is differnet in each car. They can't find the problem even after speaking to their MB tech reps in germany or their field reps thats goes dealer to dealers to try and solve the problems. I told them that I will not take the car back till this issue is resolved.

Does anyone know what this maybe? It is not motor mount nor tranny mount cause they already replaced those items...

 

Did you ever find what was wrong with it? I am currently having the same issue with my s55, the vibration goes away after the car warms up after driving for about 30 min.
