Identify the part please.

As the title says. Newly acquired C270cdi estate, opened bonnet to check fluids and this box of tricks is loose (see photo). There are two screws that appear to have held it in once, but the aperture it's sticking out of appears home made. There is an unreadable barcode and the digits R18057 on the unit. A single cable disappears, I'm yet to be able to trace it. Any ideas?

A wider shot may be helpful.

I did try a wider shot but the image was too large to upload, it's just above and to the left of the horns.

That’s intriguing! When it was mounted which way did the arrow on the sensor point?

Could it be a radar detector or jammer?

Bit of a distronic radar sensor for proximity cruise control?

Was that an option on a C270 W203?

Listed on EPC? Maybe in some markets/trim levels?

It does look like part of a distronic set up,what you can see is that it has been broken off ,leaving what I assume is the backing plate,what does the build sheet say.

It was loose when I found it but the arrow was pointing out from the car.

If you post up your VIN[chassis no] -- you will find it on top of your dash WDB 203 **********---- someone can look up the cars build [options] sheet to see if it was fitted

Traced the thin cable back along the nearside of the car, it follows the rear washer pipe then it disappears down into the depths.

It's not the distronic thingy, the hole the unit is poking out of is very home made.

 

[chrisk2010]

I dont think that is a standard or even mercedes part.

There wouldn't be a need to cut a hole in the plastic if it was.

I'm going with radar detector or something along those lines are there any switches hidden in the drivers foot well to switch on or off or control volume?

Failing that check through the fuse box and tick off what should be there and see if anything has been added.

Using Google Lense on my iPhone pointed at your picture it comes up with ... remote radar detector

Now I've wiped the gunk off the front of the unit, it has a lens which would stack up as a radar detector. No head unit inside the car and doesn't appear to be rigged up to the comand either.

 

[chrisk2010]

look around sometimes radar are rigged to little LEDs lights that can be placed anywhere maybe around the speedo or something like that. If it's an audible one there could be a little knob hidden usually in the drivers footwell or under the steering wheel.

I try to find some pictures of what i mean.

 

[chrisk2010]

Ok managed to find an american website which shows what i mean.

See the two little Leds that shouldn't be there they can be very crafty hidding them.

I'd remove it or have it removed by an auto electrician and replace or repair the plactic that the previous owner cut a hole in.

 

[Marquisofraspberry]

Cant see any lights as in your first picture and nothing apparent in either footwell.
