My ‘23 X3 M40i is my 5th BMW and all of my previous BMWs have had upgraded headlights that turn with the steering wheel. Why doesn’t this one do it? Was it available in pre LCI and taken out in LCI?

BMW had changed the system from an electromechanical system found on the Pre-LCI models (including the Pre-LCI G30 and G20 which used electromechanical), to a Matrix array system on both the Adaptive LED and Laserlights that splits into digital zones. Therefore instead of a mechanical swivel, they’ve made use of the cornering lights to illuminate the sides at tight corners, while shifting the lit zones to better illuminate those areas in addition to the anti-dazzle functionality.

Hope that helps!

As mentioned above, the LCI uses a newer tech based on matrix LED.

The old electro mechanical version in pre LCI, which has been around for a couple of decades, had a narrower illumination field that required the actual light unit output to physically swivel towards a bend. The newer tech doesn’t need this noticeable swivel to illuminate a broader field, although the light units do include low speed cornering lights, which illuminate out to the sides to aid visibility when parking for example.

In the US market some of the BMW adaptive headlights features, such as always on high beam masking, is disabled (decoded - option 5AP) by BMW.

Thanks, this explains everything!
