Usually when they stop working it is because they have burned out from running too much due to a leak. Sometimes the leak is on the pump itself at the older T line fitting on the side. If it is the new one with the updated line and it is still running, chances are there is a leak somewhere and that is why it continues to run. It could also be the relay. Usually when I replace the pump, I replace the relay as well. Try a new relay, if it continues after that, you will need to have it properly diagnosed by someone familiar with the airmatic system.
Mb dealer.?

all of the suspension is low or only one of the suspension?
if only one of the suspension very low... most the the problem is the air bellow in the suspension strut crack.. need to replace new suspension strut.

TYPICALLY this could be because the air bags are leaking and caused your compressor to overwork itself to death. The airbags are not designed to withstand temperatures below 40 degrees and above 94 degrees. Can you believe that!?!? Dry rot starts forming on the inside fold of the bag making it very difficult to detect with the soapy water test. Anyways.. i went through all these problems and several hundred dollars before I finally decided to convert to a passive coil spring system. I got it from Strutmasters.com with a lifetime warranty. http://www.strutmasters.com/mercedes-s-500-suspension-s/112.htm I have been riding on them for about 8 months now and am very pleased so far! I actually now PREFER the coil spring ride to the air ride and was surprised at just how comfortable the ride was. Hopefully you won't have to go through as much money and heartache as I did before I went for a more permanent solution. By the way, my shop only charged me an hour per wheel to install the kit so it was pretty cheap on labor too!!!!

I think that this might help you. The a/c compressor is a continuos running type there is no clutch. It has a wobble plate internally wich changes the piston stroke. Screw the genises machine-it is probably only reading a partial on the climate control module. see if you can find the self diagnoses diagram either from the factory or if you have all data. you can pull the codes right from the unit itself and they will be accurate. If you can,t pull codes see if you can get an actual value of the sensors in the a/c unit. You should be able to pull that up as well if not try the genisis. Look very closely at you evaporater sensers(left and right) you will probably see a -40 degrees-that is the sensor default input reading when the sensor goes open. That sensor is used to moniter the wobble plate position of the compressor.

check the relay for the airmatic compressor it is on the passenger side in the engine compartment right next to the hood hinge. pull the cover off and its the 3rd relay back from the front. the relay might be sticking closed but have it checked before it causes the compressor to burn itself out
