Has anyone ever seen this before. Anytime I wake the 3 up from opening the door it has an audible click from the air compressor side. but the compressor seems to work fine.

Discostew Id like to hear your thoughts on this.

I've never noticed that. Can you tell where the noise is coming from? I guess it could be a couple things. All height adjustments are inhibited when any door is open. The circuit description and operation says that when you open a door when the high speed can network is asleep, the body controller sends a hard wired signal to the suspension ECU. That could shut down the valves ? That would make a thump noise. I'll keep looking, but try to figure out more exactly where it's coming from

It sounds like its coming from the air pump area. But the pump works fine.
