Airmatic warning
Any advice would be greatly appricated.

if that doesnt work and/or you dont hear the air compressor running, youll need a shop to diagnose... usually all 4 down, all of a sudden, means a bad pump.
What caused the pump to fail is another issue. Usually a bad relay which causes the pump to continually run, or a massive system air leak/open hose.
MBWorld doesn't let us edit posts for long, which causes a problem in a working document. You may find the similar writeup - the W220 S-Class Encyclopedia at http://mbca.cartama.net/showthread.php?t=33904 is easier to maintain, so it is also easier to read.
