04 X5 4.8 SELF LEVELING SUSPENSION PROBLEMS

[WEERAB]

Best to check first thing in the morning and see which air bag is down
SWITCH ON THE IGNITION and the suspension will pump up but sometimes it will pump right to the top then you hear ssssssssssss it lowers off to the correct height
Only problem is that if this has been allowed to pump up and down for mmmmmmmmm depends on when or how far you travelled
If it has pumped up to the top 9 times out of 10 it will have knackered the level sensor that is connected to the back axle and the body of the car(just inside the rear struts)
The sensor on the front shocker or suspension is for the bi-xenon headlights and this has nothing to do with the suspension
Check the 2 back sensors for broken wires
if problem persists ill ask my autoelectrician

Thank you Weerab and Weasel for your replies - I sincerely appreciate the feedback, as I'm a bit lost in all this - but like the challenge to figure this out and to resolve it.

Here are the exact symptoms (seem to be similar to Nitrogass2000):
1) Front left (only) is very low > fender is about 1 inch above tire
2) Errors message reads: Suspension is inactive
3) The Air Bag on the front left Strut is completely collapsed (see photo in previous reply)
4) Vehicle rides "hard" and bumpy
5) When I turn on the engine, no pump is activated, car does not seem to rise or change elevation.
6) Checked a series of fuses in the glove box, high-amp behind spare tire and right hand compartment in the trunk (based on instructions found in another thread) >> All fuses seemed to check fine
7) Dashboard switch to raise and lower car does not light up and does not seem to work.

Wow, that is a lot of stuff

I guess I'm trying to avoid ordering a bunch of parts that actually dont need to be replaced.

What is your best guess what steps I could take to narrow this down and troubleshoot?

Again - thank you for your insight.
