Normal Height Only Suspension Fault

Hello all, I've searched everywhere and I can't find a solution anywhere so hopefully you can help me out.
I keep getting a suspension fault, perhaps every other time I drive the beast, usually when I'm turning a corner/on a roundabout.
My IID tool shows the following faults:

C1A10-64 (2E) Pressure fluctuates when the system is inactive - Algorithm based failure -
signal plausibility failure

C1A20-64 (2Cool Pressure increases too slow when filling reservoir - Algorithm based failure -
signal plausibility failure

U0132-87 (0Cool Lost communication with ride level control module - Bus signal/message
failure - missing a message

I've graphed the live values of suspension height with my tool, when I got a fault, and there is no visible loss of signal/reading and nothing that jumps out at me.

I'm entirely at a loss, unless I need to repair the compressor, which I think is odd given how this fault is intermittent and seems to only appear when turning a corner (perhaps indicating wiring)

Any help/advice would be much appreciated please.

The car is an 06 l322 4.2 SC.

Thank you
