Ever wanted to be able to turn your fog lights on independently of your headlights? After owning a B7 for over 6 years and getting countless questions about this, I’ve finally gotten around to doing this “5 minute” mod and it’s pretty slick, actually.
The modification is written up pretty well in the following link: Audizine DIY, so I’ll just expand upon some pointers and tips to make it easier, but essentially you just pop out the headlight switch and then use some copper wire to connect two of the prongs, then cover the old prong with electric tape. Lastly, update VAG-COM to rest of the world and you’re good to go!
Here is the rest of my pointers and notes:
- Firstly, some people have asked if this can be done with the VAG-COM only, i.e. no connecting of wires or messing with the headlight switch harness – the answer is a definite no, unless you have a very early (02-03?) B6 model, then it might be possible by just changing your VAG-COM to Canadian Settings. Anyone with a B7 will need to connect the prongs in the headlight switch, and most B6 owners will need to as well…
- While I still strongly recommend an authentic Ross-Tech VAG-COM cable and VCDS software, this can be done with a knock-off cable according to other commenters on Audizine. For specifics on how to program this via VAG-COM, check out this link where it says “Independent Fogs.” Your coding should be either 01011 for halogen headlights or 01021 for xenons with DRL.
- Wrapping the two prongs together is a little more difficult than you’d think, and whoever did the write-up has excellent craftmanship – mine is much uglier looking, but functional all the same. Use a flat head screwdriver to help guide and wrap the wire around the two prongs, as well as hold the electric tape in place.
- This mod will allow you to turn the fogs on when the headlight switch is in parking light mode by pulling the switch outward. Your Parking/City Lights will still be on, so it’s a good idea to put LEDs in there so it looks nicer as my DIY demonstrates.
- This mod is also compatible with my HID Fog DIY, so check that out, too…
All in all, it took me about 20 minutes, but mostly because I was taking my time. After testing it in my garage, it’s a nice mod and I like that I can choose when I want my fogs on or off, originally I thought this mod would turn the fogs on whenever the parking/city lights were on and that would be annoying. This is a great mod, and I’m not sure why Audi wouldn’t offer this from the factory – but thanks to PSYC0TIC ONE on Audizine for writing up a way to do this ourselves!
