rear air suspension

02bmwx54.4i · 05-30-2012, 07:55 PM

hello everyone i am new here and to bmw. i have an 02 bmw x5 4.4i with rear self leveling suspension. i made a bad mistake and no im not a rookie but i had the rear end jacked up to change tires and it rolled backwards with trans in park and came off jack. now its been awhile but the left rear air bag is going all the way down. sometimes it takes a couple hours and sometimes a couple days. i do not hear any air leaks at all. when i start it up it comes right back to normal. a couple of days ago i got self level susp. inact on the dash only for a few minutes then it went out. now it stays on. also the other day both sides were completely down and i replaced the blown fuse for the pump. is it possible that i messed up the left rear level sensor? what a bout the solenoids/valves on the pump can one be stuck open and letting the air out back through the compressor? or what about the control module? but why does it go back to normal once i start it up and then left side goes down again once i shut it off?
thanks for all your help

You can try spraying a solution of soapy water on the air bag (you can also use household window cleaner). Spray everywhere and then look for any bubbles. The bubbles will help you see if there is a leak and you can go from there. If it is a leaking bag you can purchase a replacement from Arnott industries.
