Discovery 2 PDC

New to this site, so reposting this over here in the hope that someone else out there has a solution.

I have a problem with the PDC on my 2004 D2. It has been intermittently working but in most cases has a continual tone - as if you are very close to something.

Bizarrely, when I remove the offside light cluster in the rear bumper it seems to work (almost) perfectly. If I put the light cluster back there is a continuous tone.

It doesn't matter if the light cluster is plugged in or not.

If I connect the light cluster but leave it hanging behind the bumper it also works fine.

Wiring looks fine.

I've swapped over the sensor with two of the others - still the same. Only the offside position is an issue.

All the sensors click.

I've ordered two new sensors just to see but I was wondering if anyone else has had a similar issue.

Thanks in advance.

The wiring might look fine but in this case seems to be a loom issue, let the cluster hanging while you jiggle the wirings in there with PDC on, if the symptom occurs then you know that the problem is there... the body loom which contains the PDC circuit is routed there, See RAVE - Electrical library - connector views - C2043, try to locate it and give it some contact spray

Thanks for taking the time to post - I fitted a new sensor and it seems to work fine now. Doesn't really make sense as I had already swapped the "faulty" one with two of the others and that made no difference. Maybe all the old sensors have deteriorated such that they won't work in the position.
