Also, it seems that the vast majority of problems with the rear air suspension is that the bags themselves start leaking. What lead you down the path of replacing what sounds to be everything but the bags? There's a thread on here on how to replace them.

My next step was to check the springs and lines for leaks, but I can't get the compressor to switch on in the first place. I cleared the codes and drove it and the code immediately came back.
