Hi
New to me 2009 sl63amg

I am having issues where the ride is what I would say is really unstable over uneven roads - ie over small bumps or undulations

It shudders and is unsettled

AMG have told me nothing wrong but doesn't feel right to me

Have had it rodeo-d and fluid levels looked at - all ok - no leaks or any other symptoms

Does anyone have the same issue - ie is it 'normal' for this model?

Also is there a UK based proper MB suspension specialist - indie or main dealer that anyone would recommend?

Thanks

I'd check the alignment. My CLK550 got like this and it was a bad toe.

Please explain exactly what you are feeling. If you are feeling like the rear of the car has lost it's ability to dampen out bumps and feels like it is moving around harshly, I'd say it's the rear air chamber - part number 2203270115. Is the ABC warning like coming on and going out when you hit bumps at times? I just experienced the same issue in my wife's 2005 SL500. Part cost $250 and took me about one hour to replace. Basically you remove the left rear wheel well, slide out the valve body assembly and remove 3 nuts, remove the flare nut on the reservoir and reverse the process. I'll be replacing the front air reservoir as a precaution next weekend as they tend to fail at about 100,000 miles. Good luck.

you should also replace the pulsation dampener that is in the left front wheel well while you're doing the front accumulator.
