2004 Mercedes-Benz S430 ProblemsAirmatic Pump Motors May Fail Due to Sticking Relays
The relay which turns the airmatic suspension pump on may fail causing the pump to run continuously. This can result in failure of the pump motor or a dead battery as the pump motor will continue to run after the car is turned off. Also, Worn airmatic pump mount bushings can causes noises in the front axle while driving on bumpy roads or a buzzing noise while the pump is running.
I have not had this problem fixed. I was wondering if anyone out there had the same problem. I can't get the trunk to open using the key or the remote.
CD changers, command units, voice control units, PSE units, and Tele Aid units are prone to failure, especially in early models.
