Self Leveling Suspension

[blueagle]

I had a similar problem regarding my rear air suspension . I drive an 02 X5 3.0d euro version. I already changed the left rear air bag and thought it would solve the problem. However, I observed after one day overnight the rear left side was slowly sinking ( same air bag I replaced). Based on my research about this topic, I guess my next step is to check the sensors and fuse for possible replacement ???

If you can't get a good diagnosis from a dealer or shop:

1) I would assume that it wouldn't be the fuse because if its the fuse then the airbag would not get filled at anytime, right? Its either working or not. It worth checking though, just in case, since its an easy check.

2) Since you replaced the airbag its safe assumption there's no leak.

3) Sensors ... hmm not sure how to troubleshoot this as the airbag does fill-up initially and when the X is being operated. Guess if these are cheap you can try and replace them. I guess this would be the next logical step. Maybe there's an adjustment that needs to be done, like ensuring its in the proper orientation.

4) Compressor I assume is good as it pumps up.

5) Maybe its a module. You can read up on the air suspensions more in these PDFs:
