Had new Corteco motor mounts installed. Also came with new transmission mount. Car ran super smooth for about 2 weeks. After this period I noticed a low isolated vibration felt like coming from below seat console area with car in Park. Currently I'm getting a low rumble from same area at around 15-25 mph occasionally. My original motor mounts were totally shot and gave terrible vibrations at idle or at stop light or with ac on but nothing in park or during car travel. Attached is a pic of the current mount which is about 1month old. I only suspect the mount since it appears to sit really low. Also noticed if the car is parked on a steep incline there are no vibrations after drive off for awhile however they will eventually return.
I dont think it would happen so soon or make a rattle noise. Can I suggest looking into heat shield rattle or a broken exhaust weld like I have in this picture.
Solved - Transmission mount was bad and totally collapsed after 2 weeks of service.
Yes my tranny mount was totally collapsed. The mount was brand new installed on 4/15/2015 and was a Corteco product. Replaced with Genuine Mercedes mount and so far all the problems are solved. The car was giving noticeable vibrations from the driveline, constant oscillating noise which was vibrations from the transmission obviously resting on the collapsed mount and a rotating clicking/clunking noise which are all gone now. Here are pictures of the removed Corteco mount.
Mount removed from the car.
Corteco mounting arms are totally off centered stuck in this position.
I have the same question on mine - is the trany mount collapsed or is it ok? The car has a low level vibration when idling, disappears after you increase gas or accelerate. I can stick an index finger in there.
it is not an expensive part and easy to replace... just do it
I will replace it, part's on the way from FCP. What I didn't know is how to tell for myself, if it was worn out. I am a new MB owner, so this is my first encounter with this part.
