2004 Mercedes-Benz S430 4MATIC Problems

Airmatic 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.

Leaks Develop at Differential Seals/Cover on High Mileage/Older Vehicles

High mileage or older vehicles commonly develop leaks from the differential seals and/or cover. Our technicians recommend a complete reseal of the differential unit whenever these leaks are repaired.

Engine Performance Problems Due to Crankshaft Position Sensor Failure

The engine may develop a stalling and/or no start condition due to a failed crankshaft position sensor.
