Mercedes-Benz CLS550 Problem Report
Mercedes-Benz CLS550 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.
My car is visibly "crooked". The left side appears to be the normal height, but the right side is very low. I have no warning lights or error messages. It states "vehicle rising" so when I go to drive it I think it's lifting but not all the way. When parked the right side is 3-6" lower than the left. - Visitor
Turned the car off, pump motor continued operating for about 15 minutes. Made a loud buzzing sound and then an intermittent buzzing sound. Just happened last night so haven't had a solution yet. - Visitor
ride height fine - eveb a bit high but compressor runs anyway even after shut off - I am replacing the entire system with manual springs and struts - screw them - its cheaper than constant repairs - Visitor

Noise when riding on bumby roads - Visitor
I am having the same problem as reported. The driver side of my car is slammed while the passenger side appears fine. I noticed when I shut the car off to get gas that the front drivers side wheel area was still making noise. Took the relay out for time being until I can get into Mercedes. Hope its not too costly but I'm sure it will be! - Visitor

my car currently in shop for malfunction to the airmatic system... not sure exactly what's wrong yet. my paddle shifters failed at 36k miles. I love the car but i don't think i'll buy another MB. These cars are very nice but not very reliable and for the 80k that my cls costed, i think it's crazy. I'm going to try my luck with a lexus i do believe they are much more reliable and less maintence - Visitor
