Weird Adaptive Headlight issue

[higreenx5]

1st I searched for a similar issue, found none.
2nd I have the ECS tuning BMW specific code reader

It is a 2006 4.4i never in an accident 2 owner X5

The truck has the blinking light on the headlight switch that randomly comes on when using the X at night and the lights set to automatic.
The codes only show AHL error
I erased the code

The headlights can be moved through the test function to all corners of their range.

I changed the Switch and tested a known good Controller, one located behind glove box, and nothing changed

When the light is blinking I ran another code test and it came back with no codes and can still move them with Code reader.

What else has been done
I Rewired both headlights since the wires disintegrated
I changed the Xenon bulbs to a 6k bulb
Added Can bus compatible LED angel eyes bulbs

I do not want to do a further shotgun approach since it is expensive to change controllers under lights and the LCM

I cannot find a decent Schematic of the headlight circuit, ie a PDF version.

TIA
