Rear Air Suspension programming incorrect?

[Mujahid]

Hi all, do you suppose the design/ programming of the rear air suspension could be the cause of Air pump failures.

The reason I question this is that after doing some faultfinding on my own system (which needs new bellows/ air-bags), this is what I found.

The system continually tries to fill the air-bags whenever the rear doors are opened or when the car is in motion. I also believe that it does it when the car is stationary after measuring (and recording) the height over two consecutive nights. I also removed the Air Compressor fuse, and within 90min the vehicle had lowered.

If there is a leak (larger than pinhole, smaller than bullet hole - we live in Africa remember ) and if the compressor spends most of the day trying to inflate the air-bags, would that not then burn out the Air Compressor leading to extra cost and maintenance.

And you would be none the wiser, because only when the leak gets to a point where the Air Compressor cannot keep up, would you see a visible difference - by that time it is too late. (the compressor does eventually time-out, but that does not stop it from trying again, and again, and again.)

Would be interested if anyone has experienced differently and what the BMW techs on this forum have to say.

thanks
