LR3 suspension assistance needed

Hello,

LR3 has the red suspension light on. Nanocom showing 3 error codes:

C1A13: Pressure does not decrease when venting gallery (Permanent)
C1A00: Control Module (Permanent)
U0421: Invalid data received from ride level control module (Pending)

All of this started after fitting a new compressor and 2 rear bags.

How should I start troubleshooting this?

Help.
Matt

I would do a reset of the system. Then pull compressor relay, jumper the two big slots (ign in position 2) and check that compressor runs okay. After that I would recheck all the electrical and mechanical connections you made when changing compressor and struts.

AMK compressor replaced with AMK as per part number by the vehicle VIN.

Are there any suspension gurus on this forum? (fingers crossed).
