Touareg headlamps have a bad habit of developing insulation defects inside the case. Is this something that may be the villain?

 

By all means, mine were shorting and finally the whole light stopped working, instead of spending $696.67 on a 7L-941-018-BL, armed with a lot of patience I disassembled the light and re-insulated every wire in there. Yes I've hit the jackpot.

Why self destructing wiring is not considered a factory defect, is beyond all reason.

 

The problem was with Valeo the supplier of the assembly, however my belief is that the quality control dudes were at the Golf club.

The faulty insulation is also in the Hella b-xenon headlight. I removed the harness, completely stripped the wires of any remaining insulation and recovered the wires with heat shrink.

However I have a faulty Right Swivel Module Position Sensor. This prevents the AFS from functioning correctly and throws the AFS message on startup.

I believe that some of the insulation has been caught in the Position Sensor or the sensor was damaged by the un-insulated wires.

By this statement, did you remove the lens or just the harness?

 

Both my headlights look absolutely fine on the insulation of the wires, perhaps its to do with the climate here in the UK not degrading them as quickly, who knows! Does anyone know where the AFS controller module is placed?

 

Broken left headlight now replaced with one which isn't cracked. Did a little bit more digging today namely around the fuses in the ends of the dashboard an found a strange anomaly. The fuse in the left side of the dashboard which controls the AFS cornering function was in tact but only one contact was present in the fuse box so its obviously not making a contact therefore no communications with controller. I know this used to be there as i have replaced this fuse before when i first got the car which worked for a while, but i have no idea how and why this has suddenly happened.

Is it easy to remove the fuse box without disturbing any other connections? I need to get this sorted but on the other hand i don't want to make the situation worse.

What fuse layout are you using?
I found that the fuse layout shown in the Manual does not match the actual fuse positions in the vehicle.

I use the fuse layout that I downloaded from eWin.

 

I'm using the fuse cards which are kept in the end of the dash board. I have replaced the AFS fuse as it had blown but something seems to have changed within the fuse box. Everything else seems to be working apart from the AFS side of the headlights.

Looks like buying a pre-loved Treg does not include fuse cards.:frown2:

 

Any suggestions or has anyone had a fuse box apart for inspection who can offer any advice?
