Mercedes-Benz S430 4MATIC Problems
The Differential May Develop Leaks From the Seals or Cover
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.
Stalling and/or "Crank no Start" Due to Failed Crankshaft Position Sensor
The engine may develop a stalling and/or no start condition due to a failed crankshaft position sensor.
Airmatic Pump Motor May Fail Due to Sticking Relay
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.
Squeaking/Worn Brake Pads May Require Rotor Replacement Also
Due to the size and material used on the brakes of these vehicles, the brakes may start to squeak around the 50 percent wear point. The brake rotor surfaces become uneven, causing a lip to form at the outer edge of the rotor. Because of this, the rotors are usually replaced when the pads are worn (pad life varies depending on driving style and terrain).
ABS Modulator Failure Due to Dirty Brake Fluid
It is not uncommon to encounter premature failure of the anti-lock brake system (ABS) modulator assembly due to dirty brake fluid. Our technicians recommend flushing the brake fluid every two years in order to help prevent this problem.
