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.

    Car kept reporting low tire pressure adn looked lopsided when not running. The pump would turn on everytime i opened the car door, but would only lift the car so much. While drivving the red light would flash and say the vehicle height is too low. The Benz dealership reccommened a new driver's side air strut costing $1200 just for the part sans labor! Took it to another mechanic and was told the only way to buy the part was from the dealer because of the model year, and that the air suspension is a common problem. He even had one customer who decided to remove it altogether and replace with regular struts (a 5 hr job). Unfortunately i have found no kit like that for my model year, so I guess Im forced to get it fixed and risk the other side breaking in the near future. I guess more money, more problems!

    My driver side front air system is leaking some type of fluid hydraulic I assume and when I press the airmatics button it takes forever to raise..going to Mercedes to find what's wrong

    mine is the same issue, but with the front right shock. The pump runs more often then it should to keep it pumped up. If it sits for more than an hour, the right front dips and covers the top of the tire. When I open the door, the compressor pump comes on and lifts the right front to the proper height. I assume it happens while I am driving as well. Having it serviced today, initial comment from mechanic is the shock needs to be replaced.

    Mine lowers all the way down. Turn on the key and the car rises. I replaced motor a while back and one of the struts also. It looks awesome dropped down. LOL
