2008 Mercedes-Benz CLS550 Problems

Airmatic Pump Motor May Fail Due to Sticking Relay

A sticking relay, causing the airmatic pump motor to constantly run, may causee the airmatic pump motor to fail or the battery to go dead when the car is shut off. Worn airmatic pump mount bushings can causes noises in the front axle while driving on bumpy roads or a buzzing noise.

Leaks From Rear Air Springs

Rear air springs (bellows) may develop leaks, which causes the air pump to run more often to maintain ride height. Our technicians recommend that leaking air springs be replaced.

Replace Brake Rotors When Pads are Worn and Squeaking

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).
