Hi guys I have a v9 dccd uk box in
m 97 and the dccd light is flashing and the diff thumb wheel dosnt seem tobe doing anything ????? Can anyone shed any light on it ???

 

Could be a dirty pot on the thumbwheel. Usually sorts itself if you move it back and forward a few times. Maybe you have no connection at all.

 

if that fails is this any use ?

The dccd wiring that comes out of the top of the box should make a circuit when you put a multi meter on each wire, if the circuit is broken then the fault is a broken wire from the plug leading in to the casing, they tend to break just inside the case.
