Suspension fault help

[Mtnrover]

Picked up a used 06 LR3 SE a month ago with 75,000mls. when I first got it it raised from access hight to normal hight fine but about after a week the suspension fault light came on saying normal height only, and just a few days ago I bumped the switch and it lowered to access hight and would not raise back up I could hear the compressor kick on then it would shut off. So the next morning i tried raising it again and nothing compressor would kick on then off the fault light would come on. So I turn the rover off and restarted it and tried raising it again this time I got the msg vehicle raising slowly and it raised on my why to work. Then yesterday I got the fault say suspension fault no special programs. But today After I got some new tires put on it raised form access hight to normal hight with no faults coming on. i never get all of them at once every time I start the rover I get one off those three faults

So could it be my compressor going? Or solenoid? air-dyer? or do I need a update on my ECU

Mine would only raise, could not lower, and like you said the compressor would start then stop, took it to a private LR shop, they said it was the compressor, bout a new one for $1000ish, installed, no problems since.

Messing around with the old compressor, turns out it still worked but there is a gizmo in there that stopped working, so I installed old compressor under hood with air line, now I can air up my tires after a trail.
