Hi everyone!

I require assistance in figuring out what is wrong with my airmatic?

I have read the stickied threads and it has thoroughly discussed the airmatic system but the problem im having is just with the rear suspension.

Overnight the rear of the car drops to the ground but the front is normal. and in the morning when i unlock the car it comes back to the normal height.

My friend scanned the computer and the only code that showed up was c1517. (car too low)
this code doesnt tell me anything, if anyone can help me with how i can further narrow down the problem?
Does this code have anything to do with valve release assembly?

Most of the cars discussed with the similar issue are from 00 to 02, was there anything different in the 03 to 06?

Thanks in advance!

Do you park on a hill or surface that is not level? The car will attempt to level itself sometimes.

If it comes up in the morning its fine

Sounds like you may have a bad switch or sticking relay. Why don't you disconnec the battery reset the system and recheck for air leaks
