HI ALL

I have a 2003 mercedes CL55 which has covered 60k miles, the rear suspention looks like its sitting a little higher than it should, it drives normal the abc light is not on and the car raises and lowers as normal, i have been told that it needs re-calibrating to the proper settings, any other ideas of what it could be? as this advise was given by my local mercedes specialist but when i called the dealer they came out with a list that long i cant remember lol
