Air suspension special functions not working.

Click image to enlarge

Good morning everyone, so recently I started to have compressor issues with the RR. I bought a new compressor and relay and replaced both. All was well, then a couple of days ago it started to through up, "suspension fault" then the special functions box appears on the radio screen.
Today at work the rear driver wheel looks slightly lower than the passenger side (by an inch).
I'm guessing that the airbag might be bust. I did a scan and I have posted a screenshot of the faults.

My question is could the airbag bring that fault up? Air the rear bags a DIY job on the drive? Could it be something else?

Any advice will be welcomed.

Those faults are canbus faults whereby the engine control module is having issues with data from other modules on the canbus and are not the result of a slightly lower corner from a possibly leaking air-spring. The cause of the faults may take some tracking-down.

The cause of the suspension fault message on the display could be due to the canbus fault but suspension faults will be recorded in the suspension ecu, not the engine ecu.

As you changed the front air-springs you shouldn't have any issues changing the rears.

Thank you GraemeS, I'm happy to tackle the rear air spring then.
Could anyone give me advice on how to "track" down the issues with regards to the canbus faults? Is it something I should tackle since I know very little about car electrics?
If it's not something that I should be messing about with could someone please recommend a garage/member who would be good to do the job. I'm located near junction 13 of the M60.
