So I think I have managed to have some success here with activating this wit the R-Line LED lights. Here is what I have done (using OBDeleven):
Make sure Lights are switched off
Control Unit:
Central Electronics (Hex09)
Adaption - Fernlicht_assistent - Menuesteuerung Fernlichtassistent: Change to
Present
Adaption - Fernlicht_assistent - Erweiterte_Frenlichtsteuerung: Change to
AFS, FLA, Fernlicht ueber AFS (mine was originally set to: AFS, Fernlicht ueber AFS) - This was the important change that wasn't documented anywhere else and seems to stop the rest of the coding from working.
Coding
- Long Coding - Byte 2: Change to
Hex3 (Bit 0=1, Bit 1=1)
Control Unit:
Front Sensors Driver Assistance System (HexA5)
Coding -
AFS_coding_Light_assist: Change to
High_Beam_Assist (Long coding Byte 21 - Hex 20 (Bit 5=1))
Once I had done this I now have Light Assist showing in the Car Settings Menu under Light Settings:
Attachment 29242
And when I flick the lights stalk forward I get the Light with A in it showing on the AID:
Attachment 29243
Now I just need to test to see how well it works....
