Tiny air pump sound

[Cellsaver]

2016 P90D, air suspension. A few months ago I started hearing this sound like a tiny air pump. It is intermittent and is located in front of passenger seat somewhere. It doesn’t seem to come on when I raise the suspension but I’m assuming it’s related? Never heard it for the last 6 years until now…also just a couple of days ago started getting intermittent unable to adjust air suspension errors.

air compressor is located in front of passenger wheel.
normally it only comes on after certain speed so u don't hear it
if u can hear it now then there's a leak somewhere, either air springs or storage tank, that's why u hear it sometimes
any of the corners sagging?
better fix it sooner or later, cause extra cycling of compressor will kill it
search other threads about it, there's few...
