adaptive headlights

[E53 4.8is]

so my adaptive headlights are really screwed. i have a 2005 4.8is last 7 of vin are LE83431. Anyways a few weeks ago i realized my driver side headlight wasn't working and the LED on the auto with was flashing when on. I didn't even think the issue was module related until i replaced the bulb and that didn't fix it. I have a schwaben bmw scan tool so i did a little code pulling. if i look into the LCM the only fault is ALC control module. If i go in manual activation mode the light turns on no issues. when i look in the AHL i get 2 faults: communication with stepper motor controller 1 disturb and signal fault to light switch center. If i use the scan tool to try and access the xenon headlight it says no communication available on both lights. previously the driver side light wouldn't come on at all but the passenger light would. the fog lights would also come because of the faults. Now i get nothing. when i turn it to auto, since it daylight, and switch on the fog lights the little fog light indicator light on the dash illuminates for less than a second an then turns off. Im really confused. Should i remove the bumper and switch the AHL from the left to the right side and see if the problem follows that module?
