I have adaptive Bi-Xenon and am familiar with the white screws for vertical and lateral adjustments. I just noticed tonight that my flash-to-pass lamps are uneven. The driver side light beam is higher than the passenger side. Is separate vertical adjustment possible for the flash-to-pass beam?

My Adaptive Bi-Xenons are aimed correctly as far as I can tell, both high and low beam. The H7 bulbs for flash-to-pass are seated firmly in their sockets. The flash-to-pass beam is still higher on the driver-side than the passenger-side. The theory on other BMW boards is that the driver-side flash-to-pass beam is higher for two reasons:
1) Prevent driver-side beam from blinding oncoming drivers
2) Catch the attention of a truck /bus driver in front of you via their side view mirror
Can you guys with Bi-Xenons check your flash-to-pass beams?
1) Park about 15 feet back from a wall / garage door
2) Engine on
3) Rotary light switch in the Park position (not On or Auto)
4) Pull your light switch lever towards you
Does your driver-side beam aim higher than the passenger-side beam?

my driver's side is higher for all the light settings, headlights, flash-to-pass, and high beams. I have Adaptive Bi-Xenons also. Is this the way it's supposed to be, or do i need to get them adjusted? Let me know what you come up with. Thanks.

Yes and make sure you are on level ground as it will effect your light beam!!!
