The self leveling system has two boosters in line to keep the pressure in the system when these two fail your car will sag in the rear after extended standing, and when the system get worse from bad the rear suspension will start bouncing all this will seem cute when it starts, the car rising in the rear when you start it the bouncing over bumps it is not very good for the pump if it keeps up for a long time. I am sure BMW will never admit it but the selfleveling shocks, I think, have always leaked to a small degree.

Yes, they do/can always leak a little somewhere to a degree, especially when you jack the car up, it sometimes looks as though they are completely shot - fluid (pentosin) will/can drip continuously from the the little nipple at the bottom of the rear shock. When the car is back on the ground and resting with weight distributed as it should you will find the leaking stops.
All this is pretty normal, even after recent reconditioning / resealing of shocks and replacement of new accumulators.
First hand and recent experience.
