Dreaded 5508 AirMatic Fault Code
Airmatic Pump would not turn off even after the car had been sitting shut off for a good 10-15 min.
eventually the pump shut off but i could smell like something had burnt
I think the relay may have stuck but im not 100% sure on that yet (not an expensive replacement so ill buy a new one)
I got a new pump just in case the old one had fried since it wasnt turning back on after the incident
now new pump will not turn on
swapped the relay with a relay from another component and pressed the raise car button but pump still doesnt turn on, while the car was trying to lift i checked the 40AMP fuse in the engine compartment with a circuit tester and the 40amp fuse lit up the tester but only for a few seconds now its not lighting up anymore pump still didnt turn on
I uncovered the passenger side compartment to look at the prefuse and the only prefuse NOT lighting up the tester is #74
I cleared the codes on MB II scanner a few times and code comes back, even after i clear the code the pump never turns on. the car IMO is still holding its normal height hasnt dropped much at all maybe a very little if anything. Any other fuse I should be looking at to get current to the pump?
Oh yea and i tried to check the connection at the pump plug but its not lighting up, not sure if it was because i didnt press anything on the suspension settings
thanks in advance!
with the message on your dash you should continue to see the compressor pumping air. not sure if it times out after x attempts or time frame. you might just need to get a bottle of soapy water to isolate the issue.

Any advice would be deeply appreciated!!!




you can rebuild the pump, but a replacement really doesn't cost much. not sure about the W221 but for the W211, pump replacement at home using a floor jack takes about 45 min to 1.5 hours if you take your sweet time. really easy job.
maybe check to see if your pump filter is clogged or needs replacement. thats pretty easy to do as well.
