Hello everyone again
I've managed to get myself a new ICARSOFT CR MAX and plugged it into my dad's l322 mentioned in my previous posts to try and sort the air suspension inactive issues.

This is the fault codes listed

P0443 : STATE NONE : evaporative emission system purge control valve circuit driven cycle c. Cause -signal fault


P1614: state none : electric thermostat circuit open.
Drive cycle A cause -signal fault

57 state( current) air suspension inactive/ active

78 state (pervious) left dip beam headlight defective

32 state (none) CAN BUS FAULT

74 STATE (NONE) Reservoir pressure static when filling

69 state (none) too much energy for regulation needed :rear right
Air suspension module can bus fault

Pre charge pump.

Anyone with more knowledge than me let me know the next step. I have been battling this air suspension since we bought it

Thank you for reading.
 
Ok I dont know the codes your diagnostics is giving.
But.

Did you read them, then clear them, then see what came back?

Does the compressor actually run?
If yes then the chances are its either US or you have a leak to the tank/or leaky tank.
If no then maybe thats your can errors and your problem.

The last fault says to me that, its trying to lift but cant.

The system will go "inactive" to conserve the air in the system (if it has any) if it sees a weak compressor or leak.

Not seen your posts on the the problem, but may have been better to keep it in the 1 place.

Maybe not much help but asking questions can often bring thought, or others in.

If the compressor is running, it could be a hole in the air tank but the bit that interests me here is the signal fault on a couple of components. I had a similar (but not the same) issue and found that on some cars, the spare wheel can damage the wiring loom going into the compressor, that would be worth investigating to make sure you have connectivity to there as if you've got broken wires to the temp sensor on the compressor and the pressure switch in that valve block, also there's the pressure release solenoid on that harness I think.

The compressor is brand new , we replaced it recently. Due to a previous diagnostic report.

That's definitely worth a looks as not long after we bought the car , I found the spare wheel well full of water. The spare wheel seems to cause some issues.
