The auto-adjust headlights on an 09 MS3 is just a dial that you set according to the number of people in the car... It's in the manual. If you have some tubbies in the back you put it on 4 and it angles the headlights down a bit more since the tubbies jack up the front by being in the rear.
My question is auto on sensitive of headlight when driving in the dark or bright area (day/night), not auto level as you said.
