Hello everyone! I have read dozens of threads on airmatic faults, but I think my dilemma might be unique. I have a 2003 S430 and it is leaning on the passenger side / both front and back....a lot more on the front side though. I have tried swapping the front airmatic struts and sensors too...no change. The driver side - both front and back are A-OK...and hold air for several weeks or more. I hear the pump activate when I press the rise-up buttons on the dash. The front passenger side that I am having trouble with does go up, but only ever so slightly. Still looks "slammed." Any help would greatly be appreciated. Some other tidbits of information. The previous owner more than likely had a boot (parking violations) to the driver front side and the only reason I suspect this is because when I bought it, it had severe wear on that tire...like it was dragged when towed! Does the system need to be reprogrammed. If yes, can I do this myself? Thanks again!!!

 

first when operating the suspension button "up". open the hood and spray the passenger side "strut top" with soapy water. see if you get bubbles. front strut tops were very common to leak.

 

Thank you very much for the suggestion, but I have already tried applying soap to the tops of the airmatic struts under the hood. No leaks. Any other suggestions????
