2007 R350 I replaced the air suspension compressor.... I stupidly tried to replace the relay with the car running.... it sparked and stalled. I replaced the relay and now the car starts but as soon as the compressor comes on the car stalls. Any suggestions would be appreciated

Are your battery terminals tight and did you disturb any ground connections whilst you where changing the relay?

When I have bought the car, after reaching 40km/h the engine stopped working, the same time when the air compressor was supposed to raise the car. After replacing the air compressor, it was the same, assuming the compressor was faulty. No luck.
BUT!!!!!! After almost one month of trials and errors, I have discovered that the fusebox was the issue.
So! Open the hood, on the right hand side(passenger's side), should be a fusebox. Open the lid, you will see the relays, modules and fuses. Try to remove that holder from it's plastic case. Underneath that holder is a copper strip that connects various. Check if that strip isn't melted/broken/cut/damaged. In my case that was the problem. Replaced the holder and it worked!
OR there is a quick fix! Remove the plug from the air compressor! But no more adjustable suspension, but at least your car will be running again.
Best of luck!!!

How were you able to remove the holder from the plastic casing? I can't seem to figure out how to take it apart. I have the module removed. Just need to open it in order to get to the circuit board.
