Does my rear suspension need recalibrating

Hi all, can anyone help,i changed the o/s ride height sensor after damaging the linkage. When i disconnected it the suspension went down to the bump stops,i fitted the new sensor and now the suspension will not rise back to the ride height,both the air bags and compressor are less than 18 months old and everything worked ok before even after bodging the linkage on to get home, i also checked to make sure all the doors etc. Were closed properly.

Im guessing disco 2 ??

It may have logged a fault for the height sensor out of range in which case it will need the faults clearing to get the system to fire up again.
