Hello, so I e550 09' which was recently in an accident and damaged the front left of the vehicle where the pump for the airmatic is. I have replaced it and the pump works fine. The rear right was also damaged and replaced a floor pan and rear body panel. So my question is when I turn the vehicle on, the pump starts, my vehicle says "rising" then only says "malfunction" nothing else. The pump works, air is going through the system, but the vehicle doesn't rise, the fuses are fine, relay is fine, regulator works, I'm going crazy here!!! Anyone come across this issue or can help me diagnose the problem would be great!!
