You have to run switched (off 75x post) powandroid the right pole of the fog light fuse in the panel on the side of the dash. You also need to mod the fog light relay so that it's in the "on" position. I used a small piece of wood to wedge the contacts together. You can also just use jumper wires with spades on them. Now my fogs come on whenever I want, headlights on or not.
I know the Passat headlight switch is a bit different, but I think the cars are wired similarly, if not identical.
