I attempted to change the headlight & main beam bulbs on my Audi A4 (B7) the other day but didn't have much luck! I followed this guide - Headlight Bulb Change on A4 2006 (B7) as I figured it would transfer over to a B7 fairly well. I started with the drivers side headlamp but despite undoing all the bolts the light just wouldn't pull out - it was like something else was holding it in? As for the passenger side that was even more of a nightmare as one of the bolts looks to be so far down that you need a massively long torx screwdriver to get it to it. In the end I decided to just replace the main beam ones in site - this was an absolute PITA and something I wish I hadn't started! I've never sweared so much in my life! In the end thought I managed to do the main beam ones so I've just got the headlight ones left to do. Is there an updated guide anywhere for a B7? Anyone got any tips??
