04 X5 4.8 SELF LEVELING SUSPENSION PROBLEMS

[x5mke]

Got it figured out. I have a leaky airbag. Had to take it to a shop that specializes in Imports. Man, what a lot of Jagging around.

This is the last go around for me. It's going to the stealer next. WTF?

If you found it for 140.00 there is no way its the correct thing, or its not working. These boxes are $800.00 you can get lucky and get a used one for 250.00 if you can ever find one.

I guess i am the lucky one that mine happens to cost a lot more

Thats probably due to the fact that i have the better type or air suspension, all 4 of them are controlled instead of just the rear?

Great! Proud of you. I never said in any of my posts that one was better then the other. I only have rear leveling suspension. Its what I have to work with. Glad I am only having issues on One Axle and not two!

Dont know if it saw it specifically mentioned in this thread, but on 2 wheel airsuspension systems the control box is in the battery well. On 4 wheel suspension systems its behind the glove box. My 4 wheel suspension went inactive when the battery compartment had about 2 inches of water in it. Radio module is shot. Removed the wet suspension pump relay, dried it out, reinstalled it. Then had a good local BMW tech reactivate the system. Only time will tell how it goes. But, so far so good. God this thing is a pig without a properely working suspension.

Well, after an exhaustive three weeks and visits to multiple shops we have FINALLY figured out what the issue is with the SLS. I found a guy in town that has all of the stuff to work on and diagnose issues with BMW. He started with the Fuses, all good. Next up was the checking out the connections to the pump and other places. Everything seemed to be good. Hooked it up to the computer and immediately pulled the pump apart. He was able to "Jump" two connections to each other after pulling the EHC module in which the pump started running and raising the vehicle.

When he pulled the Module out of the vehicle it was extremely warm and had a burning smell to it. Ordered a new one that will be here tomorrow. I have to pick it up from a dealer but oh well. Problem solved and fixed - Hopefully.

The ride is so much better now with the car raised and my trip to the dentist for preventative maintenance has been postponed. Everyone having problems with this system should find a shop that will really take the time to diagnose the issue from start to finish. It only took and hour to get to the problem. He said every time he has dealt with this issue, it has usually been the Module which in my car (03 X5 4.4) is next to the battery in the back of the vehicle. You have to remove the pump and the braces first to get to it. Next you will remove three Phillips head screws to get to the module. Don't let dealers and other shops give you the run around.

Hope this helps.
