Nope, I'm not touching the steering wheel at all...I'm in a Burger King parking lot...stopped perfectly between the two yellow lines on either side of me (facing due west). The building the lights are shining on is built at an angle....the left side is slightly further away than the right side.
BTW, my 2013 650ix GC also has LED adaptive headlights...but those lights are controlled by the FRM module and it does not have the coding parameters to decode VLD in Bimmercode. Those headlights do NOT perform the driver's side headlight 12° movment to the left.
So I am aware of how the adaptive headlights operate in the US market besides seeing the change in operating function on my f15 X5.
And if memory serves me correct...adaptive headlights won't pan to the left (in a LHD vehicle) when it is stationary...it will pan to the right, though. I believe this design default (not panning left) is engineered to prevent blinding oncoming traffic. The adaptive headlights only pan to the left when a speed criteria is met.
In the US market, if you have adaptive headlights w/VLD decoded (off)...the headlight still does the "reference run"...they move down/up upon engine start. But the driver's headlight never moves over the
12° like it does when VLD is active.
You can read the description of what occurs at ENGINE START UP (reference run occurs) and City/Urban Light Distribution (driver's headlight moves to the left 12°) in the description below:
