Mercedes Repair Questions? Ask a Mechanic for Answers ASAP
Hi, you need to erase the fault codes in the Airmatic control unit before the compressor will fill the air springs. It the compressor does not fill the springs after you erase the codes you may have a bad compressor or there may fault with the valve block or there may still be a leak to the rear springs. You need a factory level scan tool to erase the fault codes in the Airmatic control unit.
I don't understand your last question. What are you trying to set up?
