2008 Mercedes-Benz CLS550 ProblemsAirmatic 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.
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.
A vibration felt through the center floor of the vehicle can be caused by driveshaft flex discs, which crack and shred, causing excessive driveshaft movement. Not repairing these can cause damage to the driveshaft center support bearing, or, in the worst case scenario, damage to the transmission or differential.
