As of 3 hours ago, the auto air suspension is not raising the car to operate. The message center advises "stop, car too low". Over the past 2 hours the air leveling pump under the right front comes on but does NOT raise the front end. The console button pushed on the top to raise does nothing.

Any thoughts or advice......thanks

 

I had a similar problem, however I could not hear the pump. My compressor was out and it cost about 800.00 installed with tax, at a private mercedes specialist in Seattle. (Kirkland, Actually) that said, if your compressor is working, but no rise, then I would check for leaks. i am told if you have a leak the pump will not keep running continually, it will shut itself down permanently until reset.

From my experience I would consider a leaky air bladder/strut on one of the wheels, or a leaky hose, which is less likely. That is under a grand to fix if i remember and ebay had some for far less, especially if you are at all a do-it-yourselfer, (I think 450 per each)

be super careful driving the car when it is slammed, especially turning because it is likely riding on the frame bumpers and you risk tearing out a wheel well with a bump. (the clearance was less than my finger.

Good luck!
