Part Location on a X5

[Steve972]

Does anyone know where the air supply control unit is located??? Is this something an individual can change or does it have to be a dealer? or mechanic shop?



a part called 'air supply control unit'
regarding the source of 'selfleveling susp. inact' problem, mine had the same problem and just had it repaired by dealer. the problem is a part called 'air supply control unit' which controls the rear suspension failed. Dealer replaced the part and everything backs to normal. the ride becomes more comfortable than before. the part costs me around US$200. Before the dealer replaced the part, the warning light had displayed in the dash board from time to time, but not all the time. so do not think it is ok when the warning light goes out. once the warning light comes up, there must be some problem in it, so get it to dealer for inspection.

I believe you might have a leak (torn rubber boot) on part list #1.
Since the whole "supply control unit" part #8 is around $800 (for part alone).

Thanks for information: just what exactly am I looking at here, I am assuming below the spare tire?
