I have been brooding over retro fitting a rain sensor to my car for a while..
Its one of those optional extras that you don’t need…. Until you have had cars with them!
I originally got the idea via Whitenemisis from the following link: (So a big thank you to Peter)..
http://www.mbclub.co.uk/forums/elec...etrofit-without-screen-change.html#post815606
I have managed to source the impossibly difficult part to get, and that is the lens unit..
Remember that “officially” you are supposed to replace the screen in order to have the lens assembly..
Anyone interested can try here (only 1 left though and I cant say if they will get more)..

I decided against eBay for the actual sensor control unit as I wanted to be sure I got the correct one for the facelift version of the 203.
I phoned my local dealership and he was very helpful indeed.. I shall receive it on Saturday morning for the princely sum of £44
Sorry but I don’t have the part number for this..I will do on Saturday though.
Tonight I took the bull by the horns and set to work removing the old sensor.
If you are going to do this then a certain amount of bravery is needed..
I thought to myself, “If it comes to it then I need a new screen, but that’s not the end of the world”..
The sensor is glued with an extremely sticky rubbery type glue..
I sharpened a ½” bevel edged chisel and then got some duck oil..
My idea was to spray the duck oil and then slice through the glue in stages.. Without the duck oil the glue kept re attaching itself..
If you are going to try my method the as you slice under the plastic mount pull away from the screen. You need to try not to put excess force on the actual glass with the corner of the chisel…
My sensor seems different to the one in the link as it has 4 wires and not 3 !!
On the original post via Whitenemisis there was need of a small extra loom..
I’m hoping its not needed in my case
I know its not quite plug and play as it will need to be coded via STAR
Photo 1. Shows the screen as it was with the sensor in place
Photo 2. Shows the interior with sensor and bracket
Photo 3. Shows the screen exterior with sensor and bracket removed.
Photo 4. Shows Interior of screen with sensor and bracket removed.
Photo 5. Shows a close up of the plug that goes into the sensor.. As you can see mine has 4 wires with totally different colours
The lens is on its way and I collect the sensor on Saturday..
Then I need to arrange for coding.
So I cannot tell you all how successful (or not) this has been until that point.
I shall keep you all updated though..
