Seeking Help From China: Adaptive LED Headlights Issue

[baseyear]

Hello everyone,

I converted my 14 US version F15(yes, not Chinese version) from xenon to LED headlights. All wire harness, installation and VO 552 code works was done.

BUT, I do have issues when headlights automatically-on(night-time or in a basement garage day-time) in LOW-BEAM while driving:
1. "Adaptive headlights failure" error appears on instrument while driving speed up to 50km/h;
2. SAME error appears on while turning to right direction(turn to left no error). Very low speed (under 20 km/h?) or slightly turning are no error;
3. Adaptively follow and bright turn direction functions are all not working after error shows up;
4. Error disappeared after engine restart and all functions get normal. But then back again EVERYTIME when headlights automatically-on in driving.

Upon a software read BDC_Body, the error items in below:
(I try to translate them properly coz the software is in Chinese)
A. "AHL system damage", DTC No.008041BA related to #1 error in above;
B. "Right headlight driver module (STM): AHL malfunction" DTC No.008041F8,
"Right headlight driver module (STM): internal malfunction" DTC No.008041FD.
*The word "malfunction"could be translated to "failure" or "error" based on your understanding...

And I did some tests:
Disable C_BLC_ENA, no error again, but also disabled adaptive function;
Disable C_CLC_ENA, same with above;
Tried active VLD, but when C_AFS_ENA enable, left side headlight low-beam is half bright and half dark, and still error.

I assume the error is AHL related, but I've no idea where and which parameter I need following with...

I would like to thank all of you in bimmerpost who would provide at least a hand to me in this annoying issue, it's almost kill me and losing the FUN in driving a BMW...And also pls forgive my bad description coz english is not my first language...

did you have any luck figuring this out, baseyear ?

was the stalk needed for auto high beam or perhaps can be coded on automatically ?

Has the problem been resolved?
I have the same problem, but in the F10 LCI the lamps are not coded for error, but when I lock the car they stay on all the time and won't turn off.
