Sagging E70 Rear Suspension

[MotoLabs]

Hey Guys, I have an issue with this 2009 E70. I am getting 5F9A "Control Time Fault Lifting". I have replaced the AGM battery, the suspension compressor, the relay under the passenger side dash, replaced the air suspension control module and ran numerous tests through the Solus Edge computer and the compressor will not respond.

Any help would be great!

There was someone recently who's air suspension wouldn't respond until a fault had been cleared.

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.
