Funny thing I guess I know what I'm talking about.....

Obviously, a problem caused by the new Michelin Pilots!

Hey Skylaw...Just wanted to give you an update on the VCM, and Mikbox, couldn't figure anything out about why my voice controls on radio, and cd wont work. I have the newer VCM and still nothing?? And I'm just going w/Steve and the UHI conversion on his next Cali trip..Anyhow thanks for all your informitive helpfull posts

Hi guys, I have w220 and its been vibrating every time i start up the engine. whenever i rev up the engine it would vibrate through the seats however i notice that once the engine temperature reach 90c +. whenever i drive on the highway the engine cools to about 80C and it would start to vibrate but when i stop and let the temperature rise it would be smooth again... I was wondering if anyone else has experrience this or have any clue whats wrong with my car thanks!
Ive changed my trans mount and motor mounts recenetly

I have a similar problem at ~2300 RPM. Horrible when cold, tolerable as the engine warms up. I suspect the vibration dampener is the root cause. Interestingly, I've experienced this on other, local larger engine W220's. I think the vibration tones down as the mounts warm up; they become less rigid. Since I have an AMG, the vibration dampener ain't a cheap item for me. Saving me pennies! LOL
Cheers,
Jeff

Hello, did you ever get to the bottom of this? It's a problem that nobody seems to be able to sort I haven't been to MB but have been to 2 MB specialist and 3 other garages, plus a gearbox specialist
So far I have checked the rotors for true, replaced the propshaft ( with second hand younger vehicle c/w second hand donuts and centre bearing ), replaced the diff and drive shafts, fitted new engine mounts, the wheels and tyres have been replaced and balanced, its had a four wheel alignment.
This has been going on now for 4 years over 25k miles and it is getting worse, started small so only I could notice it as the driver, now everybody can hear it. There is a noticeable change in the "volume" of the rumble on different road surfaces. I don't use the car much for work, for holidays really and an unreliable car is not what you want 1000s miles away from home. The steering wheel and seat are transferring the vibration t omy body but not overly at my feet.
The only thing I haven't done is address the transmission or play with the torque converter.
Have you remedied yours yet?
