So a week or so ago my Self Level Suspension Warning came across my dashboard and I thought 'Well that sucks" and continued my drive... (I just have the rear only self level 4.4i)

Got to the restaurant and ate some dinner, came back out fired up the X and it was gone....didn't come back the rest of that evening. Next day, the same thing happened, I was driving along and the warning came across the dash....Got to the store and shut it off....restarted and it was gone

I parked the X after that and hadn't drove it in a day or so, Long story short now the warning is on ALL the time and its been on for about 4 days now BUT the suspension is NOT any lower its even in the back and has stayed at the same height it always rides at so im assuming the air bags are not leaking.

What could it be? level sensor(s)? I checked them and they looked ok

I also checked the fuse in the rear for the self level it was also ok.........

~Thanks in advance i'm just trying to avoid taking it to the Stealership for diagnosis, The Bimmer dealer here is absolutely awful
