Exact same issue happened with me its a simple fix !!
Take the wheel arch liner off pass side
locate the cable the goes to the drain off valve on the compressor and strip the wire and renew it,
It will lock the suspension and also will be very stiff due to it not allowing the suspension to relieve the air inside it to adjust, its almost like a permanent Jacking mode symptom,
you will find the signal wire to the electro magnetic valve broken, simply re solder it and heat shrink it and you will be away to go again
if you get stuck PM me i can always come take a look for you pending your not in scotland
