1. The rear air suspension has multiple parts that contain air/air pressure. You need to check the air bags...as well as the air reservoirs & pipes (#4, #5, and #6 in diagram). A visual inspection may not be enough...did you try spraying a soapy solution on these parts to see if a bubble or bubbles appear? Also raising the rear end to where the air springs are extended may reveal cracks in the bags.
Ditto RB...if suspension is lowering overnight...then there's a leak in a component on that side...again, look at all components that could be the culprit for leaking air (which is not just the air spring/bag).
2. The level sensor (#19) has two different part nbrs...and it depends on if you have "Xenon" headlights or not. If you don't have xenon (HID) headlights, then the sensor is for the rear suspension only...if you do, then the sensor is for the suspension AND the headlamp adjustment.
BTW...make sure that the arm on the level sensor (#19) didn't accidentally get turned in the wrong direction...which has been known to happen on some BMW models when the suspension is lifted. I can't remember if it was an e38, e39, or e53 forum...but in the back of my memory banks...I remember this being one thing to check...because the level sensor's arm can get flipped the wrong way when the suspension is extended.
