I would suggest you try the Mercedes Forum. They break the section down into specific models. You might have more exposure there. I have a '97 CL600 with a SLS suspension. that is hydraulic, not air actuated. Are you sure your car is not hydraulic? If so, there is a pump inside of the power steering assy that runs the system. mine consists of "accumulators, hydraulic struts and a leveling valve" Works perfectly. What problems are you having?
