INPA shows this:

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!

Before I ran INPA & cleared/initialized I tried to access control module functions and it just popped up an explanation of what it was. After I cleared and initialized it was "grayed out"

I think what's left to do is this:

Switching off the rain sensor
Switch off terminal 15 and terminal R (I think term15 and R refers to the ignition switch position 1 and 2)
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.

Thanks, it was in my garage, at night door closed. The only light was above & behind the X.

The auto lights work oddly, it is dark in the morning when I leave for work but the lights don't come on until I start moving. When I leave work at 4:30pm it is Az sun BRIGHT but they stay on until I turn them off.

I will try again if i have time during the day but if I don't tonight when I get home.


Thanks!

I was looking at screen caps from when I was trying to set the ride height.


If I get there what do I need to do?

It looks like you have a RLS error already . So click on it and go Next, the green arrow and you go from there. It should be instructing you...

That was a few weeks ago. It is the error I had before I initialized yesterday.

I'll see if it's back and move on from there.

Thanks!

Bingo, just click your error and make your way to the next screen, I haven't had to scan my car in a few months with DIS so memory is fading me but fmugur's answers should help!

Hope it's back.

Thanks.

Even if the error is not there on the bottom left side you have Function selection button and you can go in there and select Body or Chassis and you will find RLS in there. Select it and see what options you have... I don't remember the exact steps but you should be able to add it to the test plan or have some options right in there.
