Hi Folks,
it's all been running a bit smoothly :)
I was driving home last night and the ABS light came on. So, I tested the ABS and it still seemed to be functioning.. but definitely something to investigate.
Got home, shut off, restarted - no light. Hmm
So I hooked up the nanocom and of course there were no errors showing because I should have hooked it up when the light was still on.
Silly me
This morning, on startup, ABS FAULT on the dash soon followed by TRACTION FAILURE. I Checked the nanocom and got "Brake Switch Fault 1 time". I drove for about a mile and checked again "Brake Switch Fault 13 times".
OK - I cleared the fault, switched it off and on again* and all was peachy for the rest of the drive to work. No faults, not lights, ABS functioning (good news as I swerved round an oncoming lorry on the muddy road).

So it's an intermittent fault with the BRake Switch - is this the jobby under the brake pedal or is there another one hiding somewhere?
cheers,
Morat

*it's a perfectly valid test if you work in IT :)

Nope, no others lurking anywhere, it's the one on the brake pedal. Bit of a pain to get at though as it's a lay upside down in the footwell job.

Hmm, I'll start with a de-gunge and hope it does the trick. Are these common failures?
Thanks!

Edit: On reading up, I wonder if this will fix my cruise control? The pipe looks OK at the usual places but the system doesn't work.... Here's hoping. If the clean up doesn't work, the switches themselves don't look too expensive at about ~£30

There are two? I thought it was one unit with two sets of contacts and three wires...
Not that I've had chance to look, yet.

2 on diesel, I think only one on petrol

One is closed while other is open. They switch when pedal is pressed.

The important bit is to make sure the new switch is fully extended when you fit it. It allows it to set itself to the correct position.

There are two switches. One controls the brake lights and kills the cruise, the other kills the vacuum in the cruise system. They sit opposite each other (assuming you have an auto).
XKB000010 brake light switch
ERR2622 cruise control switch.

Best to do both whilst you are in there.
