At least I understood these cars should be new and the new cars should not do the horizontal movement at start-up. Perhaps the info is not confusing but incorrect?
Seriously, either someone has mistakenly interpreted the movement of the lights or then there still exists two different implementations (like depending on the light assembly manufacturer, but that should appear in EPC because I cannot think of mixing the two in one car).

I think they do it when the ignition switch is turned on. If the lights are set to come on when the car is started (either DRL enabled or on AUTO when the car considers it dark) you will see the beam dip and return. If the lights were not on when you started the car, they will not repeat this procedure when you turn on the headlamps.

The point of the discussion originally is that when the Active Curve technology was introduced in 2004, some owners reported that the self test now includes horizontal movement, which I have not witnessed personally. I was just trying to figure out if there was a model year difference or really why some behaved differently then others.

Someone here had posted a video of his start-up with his lights aimed his garage door back in 2004, when I questioned why my lights didn't seem to follow steering wheel turning on my '04 car, and displayed no little dance when I started my car.
Turns out my car was discribed in the sales brochure as having active curve Bi-Xenon headlights as ordered, but due to a shortage of these lights when the car was sent doen the assembly line the final 10 days of November '03, it just got Bi-Xenons, not the active ones.
His headlights did in fact dance left/right - up/down, (very noticeably- can't miss it) and mine did nothing except turn on & the eyelid opened up.
My '07 DOES look up & down at startup. Now I will have to look and see if the up/down doesn't occur if the car is started outside versus inside the dark garage... but it doesnt seem to look left & right at startup ever.
