BMW generation L322 worked on the very basic idea of aiming the headlights manually when the rig was level at normal height. Same with the P38s and Classics with EAS. At some point in the second gen 06-09 car makers got enamoured with overly complicated head lights that self adjusted to level with a sensor and motor system. I am not sure how long those lasted.
You made the comment in your opening post that your 2010 headlights don;t self adjust or level out like your other L322. Well the 2002 didn't do that... at least here in the states. There was no need for self leveling headlights if the rig is level at all times thanks to EAS. Now i have seen overly complicated systems on cars WITHOUT EAS like Lancia and Peugeot products I have worked on. That is strictly to meet EU mandates that headlights always be aimed properly regardless of load, so I have been told.
If I remember correctly you have basic HID Xenon bulbs in fixed housings 2010. I would imagine the IF your headlights really are too high you simply need to adjust the aiming screws on the housings down a 1/2 turn or so. I would not even touch the horizontal adjustments because inboard head light aiming is different than curb head light aiming. If this makes you nervous, take your rig to a competent indie or full service shop and have them check the aim on your headlights.
