reversing sensors.
Hi all, just lately when i put the car in reverse the sounder is going off constantly, Thinking it might be the control box I set out to change it as I have the dreaded water leak in the back so thought it might have got soaked, after pulling the trim out found that the control box is a different colour (mines a tourer & I got it off a saloon) although the plugs are the same, I tried it anyway & the sounder just clicked (I hope this is not normal!), so I changed it back & off it went again, I then removed one of the sensors & unplugged it & it shut up, So my questions are A/ are the control boxes interchangeable & B/ if you disconnect one sensor do the others still work as normal?, Sorry for the long winded post!.

I would check all the sensors first, put car in reverse engine off but ignition on then put your ear up to and close to each sensor if it's got a faint clicking it's ok if no sound then you have a duff sensor, this will give you the constant beep. Mine had two duff sensors replaced them and all is fine now

As above.
If one sensor fails, the whole thing won't work. Worth having a spare or two, then you can swap about. DMGRS have some on clearance. |

This is my problem too. Continuous tone on reversing, seems to be working correctly about one in ten times. Tried DMGRS but the website states 'sold out'.

Thanks for that, Mine is a 2001 tourer & has a black box fitted but I got hold of a white one off a scrappy, they both use the same plugs/connections so i'm wondering where the difference in colour comes into play as it seems they both use the same sensors?, & I cant see why there would be any difference between a tourer or saloon setup, or of course it maybe that my 2nd hand white unit is duff!.

There are a few sellers on an auction site & they are around £10 each (reduced from £23 apparently). Oh & thats how mine started off & then got gradually worse, so prepare yourself for ten out of ten times. |

Well I checked the sensors & all clicking so I guess they are o,k, Looks like it's the control box after all, typical when I have put all the interior back in!.

That isn't correct. If they are clicking it does mean they are detecting your head, but it doesn't prove they aren't still detecting something when you move away.
I found some corrosion on one of the sensor surfaces so removed all of them, rubbed them down and resprayed them. They have been fine since. |
