I can get one for about £15 and they're not much more from VAG. I'll investigate when the weather improves, it's not an urgent problem.

Too late, I already did

To be honest I was curious what the internal condition of mine was. It seems the top contacts are a little burnt.

Not much room to get a screwdriver in to prise it open either. Had to use a Stanley knife blade and still managed to break one of the clips.




Hopefully that's the problem with yours. It seems to me the main causes are the brake switch and and the F125 switch (assuming no traction control light). Since the brake switch is the cheaper and more accessible part, I'd certainly consider changing that first.
