I'll probably getted flamed for this dumb question, but here goes:
I own a 2003 M3 with adaptive headlights. I can tell when they're autoleveling, particularly when coming to a pretty abrupt stop. But I'll be damned if I can tell that they're "looking around a curve". I have yet to see any movement from side to side when cornering. Is it a subtle thing, or should I be able to tell?
I have the adaptive headlights on my X3 and they turn from side to side based on the steering wheel. I sat in my garage one day and figured that one out. I think it has to be in drive though??? ( I have an auto, i know, i know, boooooo) not sure about the manual tranny though.
The X3 must be different than the 3 series. On my 330Ci, the lights move based on speed and the physics of the moving car. With the car at a standstill and with the wheels turned to the left (or, on right-hand drive cars, to the right) the Adaptive Headlights are required by law to face straight ahead in order not to dazzle oncoming traffic. A standard feature of Adaptive Headlights is dynamic headlight range control compensating any differences in load conditions and vehicle weight. Therefore, in an M3, they should not move unless you are moving, or if you just came to a stop. They will also turn more if you are going at a moderate speed and turning a corner at a decent angle. Try this...when driving at about 30 to 40mph, make your car swerve very quickly. Go back and forth with the wheel and look at the ground. You should see the lights swivel with a small delay. The only other way to see the true beauty of these beasts is to drive around a corner in your car with the Xenons, and then turn off your lights and hold the turn signal bar to the flashing position (you will be driving with the regular lights). Since the inside/regular lights don't turn/adapt, you should see a difference. Good luck!
I tested mine today stopped at a red light, watching the lights' reflection in the car in front of me. They definitely turned, but only at the extreme of turning. I still think the degree to which they turn depends on the speed of the car, but they do apparently turn even when stationary.
(manual transmission in neutral....just sitting waiting for a light to turn green)
