Air suspension fault , will not operate via switch, flags error

Hi i have just got a 2005 disco 3 HSE auto and i have a problem with the air suspension, every time i want to raise or lower it it pings an error on the dash , ive plugged in a diagnostic xtool d8bt in that i have and these are the errors, CAR has been standing a while before i purchased and has no MOT.




i have serviced the air compressor and relief valve with a ebay kit seemed to go well , The car holds level over weeks but all are not even i.e two are lower N/s by an inch to the offside, this is my first Landrover ans was hoping to restore it back to the road, Any help on diagnosing this issue would be great.

Thanks in advance

Steve
