I have reversing sensors on the Estate. In warm weather they work fine, but when it cooler or cold the audible sound sounds continuously just like you're parked right up to something.
The guy who I bought her off says it's always done this, but I would like it to work as it should.
I've checked the bumper sensors & they seam ok :-\
Any ideas?
-
Mine has been disconnected for 3 years now with similar problem - it is a wiring loom problem allegedly.
-
Factory fit, or nasty aftermarkets?

Factory fit :y

I should add the previous owner had the car for nearly ten years & it's always done it, if that helps any :-\ :-\

Entwood posted the diagnostics routine for them...

Might be worth whipping off the tow ball Pete, as it's been known for these to cause problems with the sensors. :y
-
When it plays up, the faulty sensor(or sensors) doesn't tick. All working sensors, when touched very lightly with the right pressure can be heard/felt to tick. Much like an electric fence, but you won't be electrocuted obviously. ;D
That in addition to Entwoods guide, which involves removing the fuse shaped resistor from the loom to activate diagnostic mode which bleeps 1-4 to give the faulty sensor, should help diagnose which loom or sensor.
Then it's a case of removing the bumper and finding the fault.
IME if the bumper has been removed, and hence the sensors have been unplugged( as opposed to removed from the bumper) they sometimes give a bad connection on re connection. The little rubbers in the plug connector get filled with dust and crap, and electrical cleaner makes the rubbers swell up and then the plug won't go in.
Or it's a fault, broken wire, in the loom etc. no experience of a failed sensor, it's always been a connection problem IME.

I'd agree with Chris .. to a point .. :)
When mine played up all the diagnostics were inconclusive ... one minute one sensor, next another ... the eventual fault was found to be ....
A damaged loom from when the rear bumper was resprayed ... the idiots had obviously "stretched" the cables and water had got in ... I'm guessing the weird electrics that produced damaged some sensors
Replacement loom and 3 sensors later .. and all working fine ... :)

Tow bar removed James :y It weighs too much to carry around all the time ;D

Thank you both for the info. I'll do some investigation work :y

In that case, can I have it? ;D

Oi you! :P ;D You don't ask, you don't get... :y
MaxV6 gave me an estate towbar a while back, but as I didn't have an immediate use for it, I gave it to Guinney1971... bleedin typical... ::)

MaxV6 gave me an estate towbar a while back, but as I didn't have an immediate use for it, I weighed it in like the other pikeys do
Fixed...
