Afs error

[Commandercool90]

Hey all, I have a 2016 gti se, with lighting and package, bought the car a few months ago and I love it. However, a few days ago i got an AFS error. Had my cousin take a look at it and he was not able to recalibrate the lights via one as the car kept kicking him out due to the error code. Now upon start up the headlights do this "Dance".

Up and down then side to side, it does the up and down but not side to side. The passenger side projector is stuck facing inward. It sort of twitches when trying to do the side to side dance. We assume that headlight is the problem. Now, would it be feasible to just replace the motor that controls the projector lens or is it possibly a bad leveling sensor underneath the car? We checked those and theyre intact. I've attached a picture of the projector lens stuck inward. Fyi the wheels are straight.

You should only have one level sensor under the car to control both lights unless you have DCC I believe.

Sounds like a bad ballast or motor on the headlight. The motor is listed as able to be bought separately, but I've read with earlier MK7s it's a part of the whole assembly and cant be replaced separately.

What code did you get?

Thanks for the reply. Yes, my car is equipped with the dcc. So there's two under the front of the car and one in the rear. I did see the motor itself is available for sale. Though not too sure if that can be replaced. As for the code I will have to get that from him. It's just a bit frustrating to get this error randomly.

Any thoughts guys?

Have you tried playing with the vertical/horizontal adjustment screws? Maybe they’re jammed. It kinda reminds me of a time when I adjusted a MB headlight past it’s limit.

I’m betting it’s somehow related to the gear that rotates the projector horizontally.

Also, if you are going to attempt to fix the headlight with new parts. Make sure you verify whether you have a Valeo or a Hella unit.

You can try swapping the headlight modules between the two lights and see if the issues follows a module. Would need a code to try to pinpoint something else, as it could be a few things.

I have not played with the adjustment screws yet. I've read stories of people doing that and screwing things up even more lol. I'm going to verify what module it is exactly.

Both modules would be the same? Doesn't matter if it's L or R?

Plugged in my cheapo Bluetooth obd adapter and saw no codes. Weird. Guess it's time for a obd11

Yes, part numbers should be the same between the modules. I don't believe they have a R/L designation from my research into halogen to Bi-xenon upgrade.

I’m willing to bet it’s the problem. Sometimes when my car does the “dance” at startup my drivers side will point down and won’t come back up unless I cycle the ignition. You said it “twitches” so it sounds like the cheap little plastic gears are binding. If you remove the headlight you’ll be able to see the gears that the motor moves.

We're you able to fix the issue?
