I know there has been lots of chat about headlights, but I am still frustrated! I have a '98 B5 S4 Avant and I want to change a main beam bulb. A couple of years ago someone told me how to get the light units out so that I could change a Xenon bulb, but I've forgotten how I did it!! I have (obviously) removed the two Torx screws at the tops of the units but cannot see or find any lower fixings that I know must be there. The backs of my hands now look worse for wear! Can someone please help me remember how to get at the bulbs on this car?
