What causes Mercedes 2006 CLS500 to look tilted on one side?

I don't have an answer for this question but I am having the problem. My car is in great condition, but I continue to have this problem. When I take it into the shop, they tell me the computer is showing everything is okay. My car is a 2006 CLS500 with 78 thousand miles.

I'm having the same issue. Pretty sure its the auto leveling system. Basically balloons on each wheel to keep the car level. Trying to diagnose the problem as of 8/28/15. Any help would be appreciated.

You have a strut that is going out. do not ignore this symptom, as the airmatic pump keeps runnin while the car is on and off.. its gonna keep trying to bring the worn strut back up but eventually the pump will go out or the other side of the strut. i recommend you change them in pairs if you find a right shop they can do them for around 1400 for the pair which isnt cheap but not as bad as mb dealers

Most probably a bad self leveling shock/strut on the corner that drops lower after sitting for a few days. It will certainly get worse and may wear out the very expensive pump as well. There are after market struts for 350 range and the factory OEM are 1100 each. Worth fixing but I wish they'd cute this problem once and for all because it's been going on for several decades.
