Off-throttle vibration
Hello....2002 e430 148k miles....
It seems that when the car is cold, there is a noticeable off-throttle vibration. I can't really pinpoint where it's coming from. IF I give it some throttle, it seems to improve. Once the car has been driven 10+ miles, the symptoms seem to be less noticeable.
One note, since I suspected the drivetrain, if I am coasting (this is where it vibrates) and put the transmission into neutral, there is no change in the vibration.
Any thoughts where I should be looking?

Thanks....I recently replaced the front tires after and the ride got noticeable smoother...I had cupping issues. I may need to do the rear tires as well soon as they are wearing down. I just didn't think tires would be the culprit of the vibration.

My W210 E55 suffered (yes, past tense) from similar issues.
You may find similar info / solutions via search on this forum or another one, however I'll refer you to the MBClub.co.uk brethren across the pond where I found my answer. Search there for "W210 E55 oscillation".
The most prevalent answers (for those who have carefully ruled out wheel/tire balance / wear and other visibly worn rubber components are:
- rear subframe bushing replacement
- differential shim removal
It seems that worn out subframe bushings can cause a geometry change in the prop shaft / differential that leads to the vibration. There is an alignment procedure applicable. However, a quick (though potentially temporary) fix is to remove the shim between the differential mount and the frame. It took me 15 minutes to do, as there is only one bolt to loosen, remove, remove the shim, replace the bolt.
Wow, was it nice to drive a smooth riding car again after that...
If it comes back, I'll go after replacing the rear subframe bushings, but I'm at nearly two years since doing this and all is great.
BTW, I'm at 125k miles now.
Hope this helps!
