Here is the procedure to adjust the vertical aim of OEM Xenons:

1. Park the car on a level surface, 10 to 20 feet from a wall if possible. Connect the VAG-COM as usual, with both ignition and xenons on.

2. Select control module “55” Light Range. This is somewhat hidden under "Less Common Modules"

3. Take note of the value in the Soft Coding cell. This is the headlight level as set by the dealer when they performed the PDI. If you manage to muck things up you can always go back to this default value

4. Click on "07 Recode" and you will be able to modify this soft coding value. A smaller value aims the ights higher, and lower value aims the lights lower. Click on "Do it!" to see the lights move up or down.

5. Don't over do it. I suggest that you choose a value that still has a gentle downwards slope to avoid blinding other people on the road. I changed my original value from 00060 to 00020 and it's perfect.

6. Now you need to recalibrate the self-leveling reference point, or else you will throw a code the next time you start the car.

7. To do this, select "04 Basic Settings" and scroll up to "Group 001". In a few seconds the first cell will change from "wait" to "set". Now scroll to "Group 002" and wait until the controller says "Learned"
