Need Help Replacing the Suspension Air Compressor
I have E550 2010 (W212) So I replaced the Suspension Air Compressor with after market one , it works but now my battery is draining over night and sometimes over couple hours , I tested the fuses they look fine , they sent me a relay fuse with but it's not the one for the Suspension so I didn't replaced , it was multi purpose fuse which I have two in my car and they both look fine so any ideas what the issue could be ?
PS: I tested the battery and it was good

-- Do you have an air leak that's causing your compressor to run often ?
-- What happens to the car height when you disable the compressor while parked?
-- What corner collapses??
-- Leaks can be ... :
valves,
air shocks
fittings
(combinations thereof)

the valve has been changed and before replacing the compressor it wasn't releasing air so the front was up all the time and I had a malfunction but now I don't have a malfunction and the front went down normal but the battery is the issue

Personally I have a hard time with compressor working normally and it draining battery.
You should scan the vehicle to retrieve a list of faulty modules.

yes the airmatic is working well , I tried last night to unplug the compressor and tried to start the car this morning but the battery is dead so idk what's draining the battery
and I don't think it's a leak because with the compressor unplug for a whole night the car level stayed the same

You have a rapid battery drain.
Have you scanned for chassis faults ?
Until this is solved use a battery tender to preserve your $350 batteries.
Inspect Front-SAM fuse-box for water damages
