I`ve had to replace my brake pedal switch. It`s easy enough but just thought I`d share my experiences.
First of all though a bit of background as to why.
Some time ago I fitted a reverse camera and LED bulbs all round to my tourer. Everything worked fine for a while until I started to get a flashing glow plug light and "check system" on the dash display. This would be intermittent, it would usually come on when I engaged reverse, stay on for a couple of days and then clear itself for a few days but come back on a few days later when I engaged reverse again.
I disconnected the camera, thinking that would cure it but it didn`t. For the first day after i disconnected it the satnav screen would go to night colours whenever I braked and back to daytime when I took my foot off the brake. This only happened for a day though. Despite it being the glow plug light flashing the car ran perfectly.
Also whenever I fitted an LED to the reverse light with camera connected the satnav screen would look like this when I engaged reverse:-
A diagnostics check at Holdcroft threw up a fault with the brake pedal switch and a fault with the ECU. So going with the cheaper option first I bought a brake switch from my local dealer and fitted it today, here are some pics and a how to.
First thing to do is remove the plastic panel underneath the dash which hides all the wiring and other gubbins. Its easier if you remove the lower dash which houses the VSA, headlight adjuster and tourer tailgate switches. You only have to remove one screw and release the tight clips which hold it all on. This is the one screw:-
Once this is pulled back a bit it makes it easier to remove three more clips running along the edge closest to the drivers seat, it should the just pull out. This is a picture of the panel removed showing the clips:-
Then you can see the brake switch, it`s the grey one pointing downwards:-
To remove it I just had to twist it to the right (I think). It slides out so you can disconnect it. Fitting the new one is easy, just push it in the hole, twist to the left and reconnect it.
This is what a new £38 brake switch looks like:-
It`s too early to say yet whether it`s fixed the problem as the warning light had gone out on its own prior to fitting the switch and despite engaging reverse a few times it hasn`t come back on yet.
So thats it I told you it was easy. One word of warning though don`t do what I did and take out the old switch and put it down next to the new one to go in and answer the phone, it`s very difficult to tell which is the new one apart from a slight wearing of the push button at the end of the switch, what a plank.
One other thing there must be a difference in switches between cars with satnav and those without. When I ordered it I was asked if I had satnav. When I told the dealer what was happening to the satnav screen when I braked he said "oh yes thats right it will do that". Don`t know if he was making it up or not.
