Are you trying to retrofit xenon headlights or adaptive headlights? What was the stock setup of the car you are working on?
car for e61 from ahl. I replaced lm1 in lm2 to get more encoding options. I used this diagram to connect as in the picture. I want lm2 to be compatible with torsion xenons

Torsion?

OK first of all. You don't have an AHL unit. You did not have adaptive Xenon, prior to this install?

You did have xenon? And are retrofitting adaptive xenon?

You need to code out AHL unit from the LM2. Can you please send me a pic of the LM2 module, with the sticker.

You must code out AHL from the LCM2. As you do not have AHL Unit installed.

You need to code out the AHL unit from the LM2. If you open up NCS Dummy, and search AHL. You will have option installed and not Installed. Click Not installed.

You should not see AHL unit under the control unit tree list
