2003 CL 55 vibration after 80 MPH
Has anyone experienced this? Please help.
The tires were just balanced and the car aligned at the dealer with the service b so I'm guessing this is not the cause. Thanks


Dead give away when you siad the passenger seat was vibrating..exactly what mine does..whole car vibrates at 75mph...
The adjusted the exhaust mounts, software and everything in between ZERO improvment they now installed an E500 mount for the gearbox but it must be deteriorating with the power the E63 generates, such a bad band aid soluton
This is what i heard from the factory field engineer. There are problems with the gearbox mounts and possibly drivehsaft balancing. They even had a few worse case scenarios that the vibration is in the engine assembly. My car at idle in park will vibrate at 1000RPM to 3000 badly. I am almost thinking mine is in the engine.
My car hits 70 and my drivers seat shakes i am going insane with this problem since July 2nd. 2 dealers attempted fixes but there are no solid solutions.
Some cars have this problem and others dont it ruins ownership experience because we didnt buy these cars to vibrate at high speeds it kills everything.
I have no had it and am going to pursue a buyback unless they can fix this problem its just not fair. I like the car so much i rather have "Check Engine lights which i can easily ignore versus this crap.

I have been driving my C4s Cab daily as well this E63 is just frustrating me too much.
I'm not a mechanic but it seems rather simple.
Do you feel the vibration in the shift handle ?
Is it more in the handle than the wheel ?
Could be as simple as a U-Joint that has lost a clip or
is damaged. Or a balance weight came off the shaft.
If its vibrating in park. Thats not the drivetrain for sure.
That is motor or tranny realted.
I'm going to take it to the dealer and see what they say.
When driveshafts are manufactured they weld weights on them to balance them. Maybe the balance machine was off for a batch and needed calibrated?

I hope they are able to fix this issue for all that have it!
It is such a pain to have a fine car with stupid defects like this...

dealer around here must be slow - I can drive in anytime and they'll take me.
Thanks to all that replied to my initial question..
