I have a vibration when at idling with the car in gear. I replaced the transmission mount and it got better but the vibration was still there. Upon further investigation I found the motor mounts rubber was cracked which I believe to be the problem. I just ordered the parts today and hope this cures my problem.
I had a vibration under the drivers seat and under pedal. Also at a stop light steering wheel will vibrate. I made the mistake on buying a used motor mount at a junk yard. It worked for 2 weeks and then the vibration came back. I was afraid it could be the transmission. I bought both motor mounts new cost was 95 dlls each. Dealer wanted 175 dlls per each because their mercedes manufacturer. My mechanic charged me 100 dlls for labor. I returned the old one to the junk yard but I got credit back. It was only 40 dlls. Don't do my mistake buy them new. Now my car runs smooth and my headache is gone.
