My C63 estate has just over 10000km. Recently it has started to vibrate at high speeds. Thought it might be worn tires combined with weights beeing a bit off so I waited to see what happened after I changed tires and balanced the wheels.

It didn't help, it even got worse after a while.

Did a second check and they saw that both right side wheels were bent. (I didn't hit anything hard, but my father did once...so I guess that could have caused the damage to the wheels)

Replaced the two bent wheels, did alignment and balance of all 4 wheels, but it didn't change anything, still vibrations at 130km/h and the faster I go, the faster the vibrations are (not stronger though). They get stronger in curves then on the straights though.

Its not a very strong vibration, it was much worse before I changed the damaged wheels, but its still there and its irritating.

What is wrong with my car?

might try the front bearings too - they not too expensive and that was my problem (slight high speed vibration that was more pronounced in sweeping curves)

+1. Bearings. He is right, even the smallest little kink to the bearings and you will be offset. But also check for any arm damage or damage to steering rod.

Thanks! Im going again to MB today, will post when (if) they find the problem!

I have this problem, at speed over 120km/h there is a slight vibration and get worse as the speed builds up. I re-balanced all my wheels and re-done the tracking but its still there, did changing the front bearings solve your problem?
