As I couldn't find this elsewhere I thought I would post it in case it is of help to others.
Very easy job but done completely by feel as the switch is high up on the pedal behind the dash.
Firstly remove the lower cover which extends the dash to the floor, this is a fairly thin and flimsy bit held on by 2 posidrive screws.
feel up the brake pedal until you find the cables feeding the switch, there are two plugs one above the other. Unplug these.
On the switch there is on clip to the right hand side, push this at the same time as twisting the whole thing clockwise 90 degrees, it will then just pop out.
Putting it back is just a straight reverse of the above
It helps if like me you have a new switch in your hand to look at but once you get the feel of it it is a 10 minute job all in.
Unfortunately it did not solve my problems but hopefully this may assist others.
