Headlight Issues

A6 All/ S6 All
#1

I’ve had the afs headlight warning on my car ever since I bought it a couple of years ago and finally decided to try to fix it. I could see a slightly frayed wire going to the motor on the old headlight and figured that was the cause. I bought a used left headlight (the only one that gives me an error when I scan it with my vcds), the “new” headlight I bought brought up the same error when I installed it:

02629 - Sensor for Swivel Module Position; Left
008 - Implausible Signal - Intermittent
Freeze Frame:
Fault Status: 00101000
Fault Priority: 2
Fault Frequency: 254
Reset counter: 40
Mileage: 207288 km
Time Indication: 0

Visually it looked fine, no damaged wires etc but it wasn’t working so I sent it back and picked up a set of afs headlights with the led day light running light strip from a guy with a 2009 A6. These headlights look brand new, the wires are look to be in perfect condition. When I installed these ones I got the same error on the left light as well as:

02769 - Headlight Swivel Module; Left
003 - Mechanical Failure - Intermittent
Freeze Frame:
Fault Status: 00100011
Fault Priority: 2
Fault Frequency: 4

I find it hard to believe that I’ve had three different headlights all have the same error, what else could be causing this? I’ve tried swapping around the headlight control module between the headlights and that doesn’t seem to help. The plug looks visually fine, and all the wiring as far back as I can inspect it looks to be fine as well. I’m kind of at a loss on what to check next.

And the other issue is these new headlights are not bi-xenon, the main beam is xenon but the other light is a halogen as opposed to my original headlights. Is there a way to make these work correctly? My car was originally from the US so it has the LED daytime running lights in the bumper already (I was testing it with the bumper off so I’m not sure how that affects things) Anyone have any ideas of where to go next?

I think I had my terminology messed up with the new headlights, the main beams are xenon and that second bulb is a conventional halogen. I guess it turns on when cornering hard or something? I really don’t care if that works as long as the main beams work and don’t give me warnings lol. Is it possible to change the coding to make these work or is additional wiring required? Been searching around on line and it’s confusing as hell.

Tried switching the control units back and forth but I’m still getting the errors on the adaptive lights, plus I got a new one all of a sudden :frowning:

02233 - Left Headlight Power Output Stage (J667)
004 - No Signal/Communication - Intermittent
Freeze Frame:
Fault Status: 00100100
Fault Priority: 2
Fault Frequency: 1
Reset counter: 40

Is it possible that the control unit is going bad? I’m not sure what else could be causing these issues

For the new lights, the new main beams work and are definitely brighter than the old ones (and pointing straight ahead) the turn signals are all fine and the bright/diming switch works, I found this site (needs to be translated from German) that shows what you need to do as far as wiring and coding in order to make the errors go away - at least for rs6 headlights, from what I can tell they’re identical to what I have just with a few less led’s in the strip.

Seems relatively straight forward, I have the dash panel removed to access the module and ordered the pin/wire I need for the led light strip, I’m just going to hook that up to my daytime running light led strip in the bumper to power it. I’m thinking I’ll just try all of this and if I can’t get the damn afs to work I’ll just code it out unless someone else has an idea here
