If you listen for it you'll notice it. Sounds pretty much like an air compressor (go figure). I imagine, since you said you notice it after a few days of sitting, that the car levels out when being used?

I started her up and idled for 10 min but didn’t notice the rear leveling out.
Really don’t hear the compressor sound either, but if the compressor is shot, shouldn’t there be a code? I have a BlueDriver reader, not BMW specific but can get a bunch of codes when performing a deep scan. No errors on the compressor.
Will investigate the compressor lines for leaks, seems pretty easy to work on. Just not sure why I don’t hear the air compressor nor does it level out.
