i own a 2005 audi a6 3.2. does anyone have any instructions or anything on how to install new fog light bubls (is the H3 bulb correct?). and also does anyone know the wattage of the bulb it can handle?

 

I don't know the technique for changing them, but if it's anything like the way Audi designed them on the B5 cars, you should be able to pop off any bezels or grilles around them, and then unbolt the fog housings to remove them. Then you'll be able to open the housings and replace the bulbs. Autozone has books by their bulb racks that will show you what bulb you need for the car. As for wattage, I wouldn't go any higher than 55w, as in some cars people have melted their wiring by trying to go too high. Stock is 35w so 55w will be a big improvement (I've done it on other cars and the difference is pretty dramatic).
