04 X5 4.8 SELF LEVELING SUSPENSION PROBLEMS

[318i318is328i645i745ix5]

I have had this problem with the susp level inactive warning light coming on and my ride height adjustment button not working.

Just thought i would share my history on this...i have had it hooked upto the computer a few times before. The error appeared but when the errors were cleared it did not appear again and the ride height adjustment button started working again and the warning on the dash disappeared...for a few days....then went back to not working.

I had it hooked upto the computer again today at a local indie. He managed to clear the error and the warning has disappeared and the ride height button is working again.

I am expecting for the inactive susp level warning to come back and for the ride height button to stop working again....HOWEVER what this does tell me is that it is not the fuse, and it is not the pump...could it be the relay or the ECU module ?

How can i check if its the relay ? Are there any tell-tale signs on the relay itself that would tell me its not working ?

Any thoughts ?

Ditto. My problems have been very similar. Reset works for about a week then goes back to inact but green LED is still on but switch will not raise or lower the car. I also still hear the compressor running when we shut the car off or first get in the car.

Another thing I have noticed is that when it gets reset and is working properly I can hear the compressor running while driving the car but once it has gone inact again I no longer hear the compressor running while driving, only when shutting car down or getting in.

And here is another good one. I changed the rear left wheel for a flat. When I lowered the car down off the jack the entire car dropped to the stops on all four corners. Had to have car towed to my indy for a reset. Once reset, back to the usual one week of joy and then inact again.

Will the control module fix this. Indy said he thought maybe the compressor but not sure and the compressor seems to be working fine. He thought maybe compressor is working but not to spec so not giving the system enough air.

Oh, and I've already replaced 3 of 4 shocks and the air distribution control unit (if that is the proper term) and the relay in the back.

HELP!!! All this on top of a new water leak after fixing the sunroof drains about a year ago. Like so many on this forum, I love this car but is it worth it?

And another thing.

I think someone mentions it earlier in this thread. How about a recall. This is ridiculous especially at the cost we are talking about and if the suspension craps out while your driving it is unquestionably a safety issue.

RECALL!
