The screenshot shows that you already initialized it. After the sensor learns the new values these values should be different. I am not sure why the light values are zero but I assume there was no daylight when you interrogate the sensor.

Now, you will have to go through the steps to relearn/adapt it to the windshield. The windshield should be clean. no bubbles...
Mine has some bubbles and I couldn't complete this procedure.

In DIS even if you have no error on RLS you can go in System function if I remember right and create a test plan in there to initialize the sensor.
It is pretty much the same thing you do with INPA but it actually walk you through the steps.
I can try tonight to get some screenshots for you as RB offered. During the week I don't have much time but if you don't figure it out by the weekend I can do it then.


Here you go:

This adaptation takes place at initialisation.
Requirement for faultless initialisation is that the windscreen glass is dry, clean and free of defects in the area of the rain sensor.
The initialisation is performed using the service function ”Initialise rain sensor” in the BMW diagnosis system. In the service function, the adaptation values in the rain sensor are deleted. This is followed by adjustment of the sensor system to the windscreen based on the following sequence:
Switching off the rain sensor
Switch off terminal 15 and terminal R
Switch on terminal R and terminal 15 and wait 10 seconds
In the 10 seconds waiting period, the new adaptation values are determined and stored.
Initialisation of the rain sensor is necessary:
After replacing the windscreen
Fitting a used rain-driving light sensor
Note: a used sensor must be coded beforehand!
