Rear suspension dropping to floor unless i pull the fuse

Morning all.
The rear of my disco has been dropping to the floor overnight. It inflates fine the next morning however a yellow suspension light is on on the dashboard. Despite the light it still goes up and down as it should and special programs are still available.
I thought the rear valve block might be leaking so pulled the fuse to see if it was a specific side and to my surprise the suspension has stayed up - no air leak!
Could it be that a height sensor has gone pop?

Also is the suspension calibration on a IID tool vin locked? Read on here a while ago that it might not be!

Cheers

Incase anybody has the same issue,
I found that one of the rear height sensors didn't have an output voltage. I could see the supply was good so swapped it out for a new one and job done! 1995 Discovery 1 300TDI

Nice one Bow down
the ID II tool does indeed let you calibrate the air suspension and save various configuration setups, unfortunately it is VIN locked specific to your car. Big Cry

Ta.
Had found out about the IID vin lock a while ago. Made the leap and bought one from a forum member this past week Very Happy getting it's monies worth already! Rolling Eyes
I conveniently had a set of sensors that I bought on here when the issue first cropped up but seeings as the only side effect was the dropping suspension I hadn't bothered to get round to fixing it Rolling with laughter 1995 Discovery 1 300TDI
