c5 reverse switch fault or not?

hi,
I have a 2002 C5, recently when I step into reverse, I can not hear the usual beep. I checked and found that the reverse lights do not light up, and the parking sensors were not working.
A few days later the beep went back to work, and with it the lights and sensors. I mean, it comes and goes.
What problem do you think? Is it a touch loose in the handle?

I had exactly the same symptoms and a new reversing light switch cured it.

possibly the switch on gearbox , cant tell you where it is as ive not got my c5 anymore but my bet its on or around gearbox, once you locate it take it out and wd40 it and put it back... i had same fault on a car and this was how it was sorted ,, got to be worth a go

It is on the top of the gearbox easily visible and accessible with the airbox removed.

Easy to test.

Pull the wiring plug off the top, then using a paper clip, make a U shape and connect the 2 prongs inside the wiring connector together. Put the ignition on and look at the revering lights, if they are on the wiring is all fine so the fault must be the switch.

Regards.
Martin.

It is in the centre of the photo, inside the pipe to the clutch slave cylinder and with a black 'accordion' lead with a white stripe on the side attached to it.

Yes, the beep returned on mine with a new switch fitted.

Have you tried Martin's suggestion, simplest method of determining if the fault is with the switch or elsewhere.

Hi, remove switch, remove sealing washer and throw away, put switch back using sealing tape or past.

Worked for me! Dave.
