PDC Sensor removal?

[steveatesh]

I'm having a problem with a rear PDC sensor - the inner right hand side one - sounds continuously if it is raining and reverse selected.

Quite a cheap part at AstonMartinParts but how the hell do you get it off?



This is the offending sensor. I crawled underneath and thought the bracket would come off easy (big mistake) nor could I see any obvious fastening for the sensor. I'm hoping I can remove and replace the sensor itself without taking this bracket off.



Any clues anybody?

Right, I've just been and had a look at mine, first thing to do is to remove the plug, then there are two retaining clips/tangs top and bottom of the sensor, I was able to open these up with one hand and then the sensor pushed through from outside to in.
Hope this helps.

That's great thanks David. The wiring seems to be secured onto the back if the sensor.usually there's a trick to getting them off, do you have to compress it, open it up a bit or another trick to getting it off? I'm asking because I couldn't release it easily to pull the wiring off?

I've just taken a few pictures that hopefully make things a bit clearer.
The plug is removed by pressing in the clip just by my finger that can be seen in the first picture (please excuse the dirty fingers), in the second picture you should be able to see the two tangs that need to be spread out slightly to allow the sensor to be removed. The final picture is the sensor removed.

That's a really big help, thanks ever so much for taking the trouble to do that, I really appreciate it

Right got this done today, part was £48.00, plus 30 minutes of my time, but would have been a lot more if it wasn't for daves help above, so cheers mate really appreciate it.
The original part was broken in two when I removed it so no wonder it wouldn't work. I believe it must have either been cracked at manufacture or at assembly, but has only recently become a permanent fault for some reason.

Looks like standard Land Rover (Disco 3) - might be cheaper that way
