I had this same problem. I ended up ditching the air suspension for coilovers, but in inpa I did note I had a front level sensor "offset" issue. As an aside my auto leveling headlights would not work properly either. As soon as I reset the offset issue my headlights worked. Not sure the two are related, but I wouldn't be surprised if the reset wouldn't have fixed the air ride too. In the end I was tied of dealing with it.
Perhaps try the reset of the ride height sensors just for s's and g's?
