I have a new cable with which to edit the coding of the car and do scans etc,
Previously I had fitted a Rain/Light sensor to the car where there was none. Not even the Light sensor.
The coding for the roof module has no light sensor in it, and seems to add up to all the options I have.
The central electronics module is where the coding happens for the rain/light sensor, but the car won't accept the code. It only has an issue with the rain sensor number, the others it was fine with.
Would there be any reason for this? The rain sensor actually works. But Automatic headlights do not. It shows an Auto headlight error on the dash.

It doesn't let you to code it because it's not configured in the system? Is there a place to add the rain sensor module, like a check box on the head unit or something? Like when I added the back up camera.
