Going absolutely crazy on this 4.8is suspension. Any Help?

[m3j0n]

Car is an 05 4.8is. Slammed to the ground, "suspension inactive" message, no light on the ride height selector switch.

Arnott struts on both fronts, arnott bag on rear passenger, original used bag on driver rear.

pump does not turn on. Tested fuses in rear compartment - they have 12v.
I have scanned the car with a generic scanner and found driver front sensor is the only one out of range (-206mm) in comparison to the other 3 readings (between +20 to +60mm). That sensor did have the clip broken that goes around the lower control arm, but was still mounted solidly. I went ahead and replaced it thinking maybe it got damaged. Replaced level sensor, and rod/mount/clip. Still giving the same reading.

Pump does turn on when I give it direct power, however, suspension does not raise with pump on and cannot hear any leaks. Scanner is reading Pressure in accumulator says 7.4bar. Scanner reading that all valves are closed. I cant understand why the pump wont turn on in vehicle accessory or running position.

Should i throw in a 2axle ride height computer? Is it plug-and-play, or does it need to be coded? I have read both online. Damn thing is expensive....How is it accessed? Do I have to take the glove box out? and how can I test my current module?

I have read horror stories of people going broke trying to fix their suspension by throwing parts at it. It looks like im already starting to go down this road. Anyone have any tips?

ANY AND ALL HELP IS APPRECIATED!
