My car is in good order and travelled 310k kilometres.
It has developed over the last several months a minor but annoying vibration that seems to come from behind.

It is a thrumm...thrumm...thrumm...
Low amplitude
From 50-90 kph
Seems to get better when car has gone a few kms.
Seems to almost? disappear at 100km+.
I believe it is very slowly getting worse.
It changes with speed and throttle, ie the frequency and amplitude.
It seems worse at neutral throttle.

My wife does not care and my Benz mechanic cannot find it.
It drives me nuts!

New rear tyres and new engines mounts made no difference.

Thanks for your help.
