Managed to break the left hand switch changing the brake servo, It doesn't do the brake lights as the other one seems to do that, so I assume it is the cruise control switch?
Just looking on ebay/rock auto and the same looking switch is listed as the brake switch, are the 2 switches the same? Don't want to take the brake one off to look at it and bugger that one up too.

Oh, and that bottom bolt on the brake servo, what a crap design for shovel handed people!

Well I can answer this now. The left switch tells the ECU if the brake padel is pressed, one of the things the ECU then does is drop the max torque. I had forgoten about this switch & had been chasing intermittent issues with low boost. Found the info re the ECU & remembered I hadn't swapped the switch over. New switch fitted & no more boost issue smile
