I have been having an ongoing issue with my 07 V10. When I start it, I get a bulb failure indicator warning on my speedometer display. My MFI reads "AFS No Function. Veh. Wallet."

I have already taken my Touareg to the dealership 3 times to get this fixed. Last week they replaced a portion of the wiring harness but tonight it did it again.

I have checked all the bulbs and everything appears to be working. I have checked my controls and equipment & Tips manuals but am unable to find anything concerning "AFS No Function. Veh. Wallet." It is getting very frustrating to hear the warning buzzer each time I start my Touareg. Can someone please help me s oI can tell my dealership what to fix?

Thanks,
Jerry

Do you only get the warning when the headlights are on, or during the day too?

Maybe one of the headlights has had a failure of the component that causes the AFS lights to turn? Or a bad controller? Or a bad cornering light or something along those lines.

I'm going to assume that you don't have a Vag-Com. It would be nice to see what the error warning actually is.

I don't have a Vag-Com. It happens with the lights on and off. The first 2 times they replaced my passanger side front light. But those 2 times it was not coming on, all my lights are working now.

My wife said the same thing about the "wallet warning". I keep assuring her that it is all covered under warranty.

I just had this same problem fixed about a month ago on my '07. It has something to do with one of the sensors for the automatic headlight(turn the lights on or off due to outside light). I do not remeber exactly what they replaced though. I am away from home for a week but I can look at the dealer reciept when I get back to see exactly what they replaced to fix it.

It went back to the dealership today. Trying to recall the phone call this afternoon as close as possible. They said that when hooked up to the computer it is throwing codes for everything. That they have never seen anything do this before. That the codes are telling them that nothing from the headlights back is being reconized. They said they are having to call VW for tech support and that it might be a couple of days before they hear anything. They asked to keep the Touareg and that I should hear from them later this week. More to follow...

Hang in there. At least they didn't give you the old "failed to duplicate" line. :rolleyes:

No communications from the light. Hmmm...Can-bus error or failure of the can-bus controller in the light itself? Perhaps something throwing garbage/noise into the controller network and throwing off the diagnostics.

Don't sweat it. Seriously, now that they know it is broke, they will fix it.

Your only cause of anxiety at this point is: "How long will it take the get the parts!" :anger:

What does "AFS No Function" Mean?

Drat. Nobody has answered that yet. AFS is the term for those fancy Auto Focus Steering Headlights that turn with you as you turn the steering wheel. It just means that when you turn on the Touareg and it runs the quick diagnostics, the vehicle has determined that AFS system is defective and will not work.

Or to translate "Yo homeboy, them 'dare fancy moving hi-beamers have crapped out on you."

How wonderful is this forum, i have got the same problem since last week and now i know what to do instead of financing the workshop's R&D!!!

BTW, the signal appears on and off, even without the head light turned on, same experience?

Million of thanks guys!

The AFS is your adaptive headlights

The AFS is your adaptive headlights- that illuminate the corners when you are turning. You can check them out and see if one of the turning lights is out, on the "new body" style Touaregs these lights turn on and off every time you turn a corner- and those kind of bulbs seem, to me, not to be the kind of bulb that takes kindly to being turned on and off repeatedly. Start the vehicle up, put it in drive (facing a wall or garage door) and turn the wheel to the right and to the left. You should see the bulb illuminate when you turn each direction- if it does not, or does in only one direction, you may have a bad bulb.
It's pretty easy to change bulbs if that is the case- there is a small release tab on the back of the headlight assembly (inside the engine compartment) and then you simply push inward on the outside rear edge of the headlight lens- it will "pivot" inward, and then you can slide the whole assembly out, remove the back cover, and replace the bulb.

NKTOUREG, thanks for the tip, i've tried it out upon receiving your message, everything seems fine; so it's not because of the bulk.... it might caused by bad wire connection, i suppose. But i tested just now without the warning signal.

Just wondering, the signal (I am referring to AFS No Function) appear due to the light faulty AND when light switch's turned on? or even the light switch's turned off?

Sometimes i see the warning signal during day time where the light switch is turned off.

Sorry for my broken english, wish you understand what i'm talking about:confused:

Many thanks

Hello folks,

I also have the same error code on my 2006 Touareg with bi xenon. The cornering light are working. The only strange thing I have discovered is that the driving lights are far too low. They are only lighting up 15-20 meters in front of the car.. Could it be that the automatic height leveling system is out of order and that the afs fault message tells this??

ME too!!

Sorry, I am new and completely car illiterate and a single woman. :(

I read the posts but still am unable to explain exactly what needs to be fixed. Can someone recap? I have the added problem of having to translate it to French (I live in Tunisia) and the car dealership here is clearly the devil. Your help is appreciated.

Thanks a bunch!

The lights will default to lowest position when there is an error in the levelling or AFS systems. This is because they no longer "know" where level is, so to be safe, they simply point at the ground.

Same problem i had about a year back.

It was caused by bad connection at the headlight wire socket, it's not like ordinary method like other type of cars that rely on connector. for T1, We push in the headlight into the plastic tray/housing then the wire socket will be connected,

As for my case, the headlight couldn't stay in position because the lock at the headlight tray/housing that hold the headlight broken, so the wire connection was loosen, hence, the headlight did not function and the other side headlight light beam pointing 15-20 meter in front. Other functions of the headlight did not work as well (mine is 2006 T1 with auto adjust headlight)

After the replacement of the plastic tray/housing, it all back to normal

Wish this help
