Hello, all. I have searched through the forums, and gone back as far as I can, but did not find this particular problem:

My Disco seems to adjust the suspension at EVERY stop light, and even when I slow down to a crawl. When I got the truck last year, the bags were replaced, and I have not bottomed out as others have. However, when I stop at a read light, I feel the compressor kick in and raise the rear, then I hear a hiss (sounds like it's coming from the compressor), and it drops back down. This is not a full drop, but rather a short one. Has anyone had this problem? Can anyone offer any suggestions? Is it normal? Any would be greatly appreciated. Thank you

 

Need to get it to a mechanic that has a scanner capable of reading SLS codes. You will know from this what is wrong, it could be something as resetting the system thru the ECU.
