Rain & Light Sensor – Retrofitting

Share Button

Mileage: 114,501KM

This will be the final mod which is related to my existing modifications on MFD and COMM2000. To have the rain sensor involves a large sum of cash if I want the outcome as according to factory specification. It requires a different type of windscreen which has all the necessary parts to fit the sensor. Alas, I’m still using my current windscreen because TBH, I was a bit skeptical on the end result. Let’s have some experiments first and I will deal with aesthetical features later on.

 

 

I managed to secure an used unit of rain sensor from abroad. Cost me around GBP20 including shipping. Additionally, I need to procure silicone adhesive pad to fit the sensor onto the windscreen and it cost me another GBP9.50.

Apart from the above items, I replaced my end stalk button from another spare COMM2000 for auto lighting activation.

If you would like to buy the rain sensor, just make sure it comes with the IR plastic lens and in good condition. The condition of this lens will affect the sensor efficiency.

 

Rain sensor cable

 

The rain sensor cable was tucked inside the roof headlining, somewhere above the driver sun blind. Routed the cable to the center of the roof.

 

The sensor connector

 

 

Since my windscreen is tinted, I need to make a cutout to make sure it won’t interfere with the sensor. Using the sensor lens as the template and glass cleaner to clean up all the adhesive residue.

 

 

While waiting for the windscreen to dry up, I begin with fixing the silicone pad onto the sensor lens. The fixing is a bit straight forward but just make sure it won’t create any air pocket and covers the whole sensor points (eight for the wiper and two for the light). The pad was fitted slightly to one side.

Next, I proceed with the replacement of the button stalk while waiting for the lens to be bonded perfectly on the windscreen.

 

All is done, view without the rear view mirror

Well, I could not fix the sensor as per factory specification. Lack of vacuum environment which is crucial in fixing the sensor hence a few bubbles appeared. Anyway, as long as it did not obstructing the sensor critical area, it’s good to go.

Yeah…. All the hard part for this modification is done. Now, it is time for the configuration and hopefully PP2000 able to activate the sensor.

Testing out the end stalk button

 

From now on, my intermittent wiper speed will be replaced by auto wiper speed. Activating by pushing the stalk upwards.

 

 

Auto light can be activated / deactivated by pressing the signal end stalk button for more than 3 seconds. It can only be done when the key is turned to ACC (1st click).

 

 

Since my BSI has the recent version of software, there are some differences in operation compared with the earlier version of BSI. For example:

  • The follow me home light will not activate automatically when switching off the engine on my car. I have to use the pull stalk method.
  • The automatic wiping function will be activated all the time (does not matter if the car ignition has been switched off previously) as long as the stalk is resting at intermittent position.

  • Very well done. The first and perhaps the only 206 Bestari with retrofitted rain sensor. Is it accurate in intermittent operation when subjected to varying rain intensity?

    • Yup the intermittent operation is pretty accurate but sometime it does get confuse and max the swipe for a couple of swings before resting on the correct pattern. It must be my windscreen. Can help me source the part?

      • If windscreen is insured you could get a new windscreen for free or almost free. Out of the 14 windscreens listed, suitable for your vehicle would be any of these.

  • Hey! I’m trying to follow your tutorial, but i’m unable to find the rain sensor cable from where you said. I took some pictures of the cables coming up the left sidebar and these ones are what I found:

    Could you give me a hand here? It’s a 206 Quiksilver from 2007, therefore, one of those cables should be from the sunroof.

    Thanks in advance!

    • The cable is not at the pillar. It is tucked in the head lining somewhere at the sun visor area (across the roof, parallel to the windscreen). The cable is hidden from the naked eyes but if you trace the main harness, you can find it. Just search the cable with the same socket as shown in my post. Happy hunting!

      • I found it! It was hidden behind the sunroof motor, practically in the middle of the windscreen. What I can’t find on Ebay, though, is the silicone pad. Where did you buy it? Or how should I search for it?

        Thanks mate!
