This problem seems to be reported a lot on forums. No one had a real solid answer for me. So I started replacing parts and testing them. I replaced the shocks first and that didn't help. I went for the compressor next, since I sprayed it with soapy water and there were a few spots that bubbled up. that also did not fix the issue of not staying inflated during driving. Lastly I replaced the air lines. I even went as far as sealing them into the holes. It seems to be a cheap design on where they plug into. Still didn't fix the issue.
I resorted to just turning off the car and starting it when I could. That would get me 2 pump ups at a time. Then i would have to shut it down again. The last thing i was going to change was the control unit for the suspension. I knew my level switch was working from testing it. The control unit was 400 bucks new, and I didn't want to pay for that yet.
One day it just started magically working! I noticed that the shocks were staying inflated over night and during the ride. The compressor would even turn on at a stop light sometimes. They only thing that I can think of, is the control unit somehow reset without me doing it. We did have some very cold nights last winter. May have been cold enough to loose power from the battery. We didn't drive it for about a week that week. it was about 30-40 degrees warmer when we did.
I would check for leaks and signs of issues first. Once you have those sorted out. Remember to disconnect the battery for a bit and see if that helps too.
