Yeah so i gather, so decided to take it off and have a look. Turns out the central pivot of the pedal is plastic and it had snapped off where it goes into the electronic part of the pedal.
So i drilled a hole all the way through the spindle and inserted a small drill bit with super glue through it reassembled and left it to dry over night.
Have just refitted it to the van and now its as good as new, simple job to do and cost nothing but small amount of time.
Thought i would put it on here so if any one else has this problem then there is a simple solution available to them.
