Land Rover Repair: Air Suspension Inactive warning, rovacom, speed bump

Question
HI,
My "Air sunspension inactive" warning is flashing on the board, but the suspension seems fine. I think it is locked in the suspension position indicated by a line on the indicator infront of gear stick, also the rotory hold switch light is on which means it is locked in position.  Basically I think I hit a speed bump to quick and the jeep automatically altered the suspemsion and locked it into position. However if I press the rotory button it does not unlock , suspension stays in same place and warning is always there. Is there some way I can unlock this? Maybe it is a sensor or elctrical problem.
Please help, thank you very much.

Answer
This sounds like a sensor problem, you'll have automatic operation, without selectable control, and yes, it's locked in standard height.  

Unfortunately the only way to clear the problem is to plug-in with a Rovacom or Autologic, or the dealers Testbook.
