Compressor or AllTerrain Module ?

Hi,
I seem to be plagued with suspension issues but here's the latest one i could do with some advice on. A few weeks ago the typical errors showing on startup which i thought would indicate a battery issue so i thought as it was 4 years old it was about time to replace so new battery in place there was no change.
The car is set on the stops as if no compressor working so i replaced the relay and checked the fuses which made no difference. I now get the special programs off message on startup but the selection wheel on the special programs shows and its not showing the special programs icon on the 4x4 info screen as per the link but also all 4 wheels showing as red rather than green so im struggling. Also checked if any wheels were flickering in the screen to indicate a height sensor issue but nothing moving erratically.

So i plugged it into my neighbors snapon diagnostic and ive got the below errors.

C1A02 - rotary encoder stuck in the intermediate position
U0421 - Invalid data received from ride level control module
B1B02 - Low frequency coil
B1C57 - start ignition relay coil

then within the body control module which i dont know if i just started listing the errors or its a list as the snapon diagnostic is bloody hard to use.

B1A00 - Control Module
B1A99 - Reset
B1B02 - low frequency coil
B1B05 - Key 3
B1B06 - Key 4

Any help on what i should do next would be greatly appreciated. I should mention the compressor was replaced with a dunlop compressor about 6500 miles ago so i do not think that could be it in that space of time.

As always the expertise here hugely appreciated.
Thanks

Just an update here.
I pulled from front valve block apart which was stuck on the centr piston so I waned it and it’s went back in only to still have the compressor issue. I got a repair kit (Dunlop compressor) from 4xRAirses and replaced everything and it worked fine.... for 24hrs.
Now I have nothing working and the amber suspension fault issue on the dash but it looks like he he front has dropped a bit.
In looking at the 4X4 screen I see the front left looking like it is out of line but does this mean strut leaking or height controls sensor ?

Did you do anything about the rotary dial problem. Possibly pull the connector and give it a clean as well as the dial. This can do odd things to the suspension Embarassed
