The ECU AIR SUPPLY CONTROL UNIT ($800 white box) in back where the spear tire is. Will keep you informed! P.S. Did you get yours fixed and if so, what was the problem?

James, very interested in where this relax under the air supply tank is. could you please point it out? I found a relay for the air suspension in the truck right side compartment by the fuses ( relay #6 according to realoem ) but could not locate any other relay that you are talking about.
PS. It seems that the X5s with the air suspension in the rear only have the relay right on the air compressor but not for FULL air suspension such as my 4.8is
