I have a 2000 S500 and have been told by the mechanics at the MB dealer that my air compressor is out (I am getting the notice to visit the airmatic shop) and I have also been told I need struts. This information was given to me after I had already dropped 1k for what I thought were minor problems (tail light, side mirror signal light) so needless to say I wrecked the vehicle back home. I have had the vehicle home for several months sitting in my garage and it was completely on the ground. The other day I decided to get it jumped off and pushed the button for it rise up, it rose but just barely over the tires (you can fit your hand in between the tire and the car barely) and it will not go up any higher and the visit workshop is still on. I am ready to get it fixed but I don't want to spend all that money for no reason. I need some help and advise! Sorry for the long post!


If that's the case It is most likely the air compressor that is not genertating enough pressure. You can hear the compressor work but it is required to generate enough pressure within a specific time interval. I bet if you get it tested it will fail.

Final question the mechanic said I needed struts too is it necessary to get both if it's the air compressor. The mechanic states he would not put struts on without getting air compressor fixed because it would not work. Please advise.

Only sure way to know the extent is to use a star diagnostic scanner system to test leakage issues from compressor, valve block, pressure resivor, or spray soapy water where airlines connect to struts. These airmatics are nice but also a pain when it's time to fix. I just fixed a 2000 s500 myself. It was sitting on all 4 wheels and wouldn't raise up but compressor pumped. It turned out to be 3 busted air struts. I replaced those and it's up and riding now
