Already Tried:
My car is a 2005 BMW X5 4.8is 4.8L, V8, Six-Speed Automatic, a 4 Door SUV AWD.

I live in the Middle East, in Doha, Qatar, bought the car used in October 2008 with 93,000km. It has now little over 100,000 km. I have been in contact with BMW in Germany regarding the repeated self level adjustment inactivated message. I was first told that the compressor had to be replaced. I doubted that. They reviewed the record again and suggested the airpump was working constantly and had to be replaced. Another expensive repair. One day after I get the car back I have a low tire pressure message. Drive the car to a tire center to check air pressure and for punctures. All is good, so they reset the low tire pressure message. Less then a week later I get an extremely unsafe feeling driving and bring the car in again. It turns out that the right front shock absorber is leaking and needs replacement. Is it possible that the self level adjustment problem has been all along linked to the failing shock absorber and I have been taken for a ride on the airpump replacement? Any advice is appreciated.
