Pull the hoses off the controller under the seat and if that doesn't work
Get under the car and push the lever on the side of the diff.

Isn't there an electronic connector on the controller? disconnect that and diff locking should stop engaging

Which way did you have to move the end of the lever arm to disengage the diff lock? Towards the centre of the car or away from the center of the car?

Now that its disengaged will i have done any damage to the diff by driving the 50 miles, i kept the speed to around 55mph.

I did 120mph with diff lock no any damage

Hi i pushed the lever towards the front of the car, i then checked the switch and the green light had gone out and also the orange one in the clocks. i then drove the car and all was ok.

Towards the front of the car? Would that also be towards the propeller shaft?

Hi yes.

Hi yes.

Thanks. Confirms that I was wrong in my thinking.
