d3 suspension cry for help

Hi I am looking for help to fix a disco3 2007 lhd with suspension problems. A nanocom was used to read the dtc's after deleting the list of problems the ones that came back were as per photos attached.
So farI have disconnected the exhaust valve and when powered it clicks, and have the lh headlamp out to look at the multi connector and wires there which look fairly clean and none broken. My next thought was to get back to the control unit and check that the supply from there to the exhaust valve had continuity. I was going to remove the exhaust valve to check it is clean and not sticking but as the unit was new this year thought that was unlikely to be the problem.
I don't have easy access to anything other than an old snap on ethos code reader, my series cart spring land rovers diagnostic sockets hold my eyeballs if you get the drift.

Saying the exhaust valve or wiring is faulty.

It’s part of the compressor.
When you lower the car it should hiss. That’s the exhaust valve working.

yes I understand that the dtc says its not working and the other dtc point to a module failure which is apparently unlikely so I am trying to establish what else it could be
