This sounds eerily similar to my issue as well and has me scratching my head here… 06 LR3 v8…

New battery recently (voltage and charge are perfect), new lower control arms at the dealer (mine were toast) over a year ago.

Never had issues other than water ingress which came from the sunroof drain tubes and air cabin intake box. Fixed those quickly. Vehicle was fine… last 6 months started to get issues with air suspension compressor becoming audible and remaining on for a while before shutting off once heights was reached. Might be the springs have some loose… still need to investigate and redo the desiccant and clean the filter on it.

Replaced parking brake switch behind the pedal as well.

Recently started losing dynamic stability control, then occasionally could not raise or lower suspension and it would only stay in normal drive height.

Ran my diagnostics tool (iCarSoft CR Max) and would occasionally see an ‘F’ on the dash with a message that special programs was off.

Annoying but I could clear codes and it would be okay for a little bit before they came back.

Suddenly the front end air suspension is lowered and won’t go up, numerous error codes. Steering angle sensor is fine, checked the collar that is a challenge of yogic proportions to glue back and it is fine…

Yesterdays codes::

C1131-92 air supply
U0416-86 invalid data received from vehicle or control module
C1A20-64 pressure increase to slow when filling reservoir

P0562-00 system voltage low

B1B78-84 system pressure
B1B82-00 Rear air distribution stepper actuator
B1B83-00 rear blend stepper actuator

C1A56-93
C1A58-93
C1A60-93
C1A62-93
C1A64-93 all of these pertain to the tire pressure and transmitter assembly

B1A00-47 control module
U3000-54 control module

P0562-00 system voltage low

U0122-87 Lost communications with vehicle dynamic control module

U0402-94 lost invalid data received from transmission control module

U0426-94 invalid data received from vehicle dynamics control module

U0421-94 invalid data received from the ride level control module

I am suspecting a CANBUS communication issue is causing this flood of errors.

Pulled the engine top cover off, did not see any damaged wires.

Will check engine oil temp sensor wiring based on similar issues mentioned above.

does this seem eerily similar or am I missing something obvious?
