I asked over in the lighting forum but haven't gotten an answer.
My headlights are pointing WAY up into the sky at night. When I start the car I see both beams of light move up and down indicating that the leveling motors work ok.
I checked the front and rear level sensor arms, they're connected and everything's fine there. No codes being thrown.
I've tried adjusting the white screw on the headlights but I think the leveling motors are self-correcting as I try to adjust them because the beams of light don't move at all.
So apparently this is all done via the ECU. I saw in the thread I replied in that was about an A6 how to adjust the lights using VAG COM. I've gotten in touch with someone local that has it that is willing to try to help me out.
Can anyone confirm if these steps are correct? I really dont' want to drive my car at night until I can fix this -
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"
