How to replace brake light bulb audi a4 1.8t 2002

Start by opening the trunk lid. On the sides of the trunk, just beside where the trunk lid sits when closed there is a circle cap on either side. Remove the cap it is the same material as the trunk side trim (fuzzy carpet) then there will be a screw set into the hole that you just uncovered. You can use either a philips screw driver or an 8mm socket and remove the screw/bolt. you may need to reach in with a set of needle nose pliers to remove the screw after it is loosened all the way. Once the screw is removed grab the tail lamp assembly from the inside and twist the tail lamp out of the holding pins located on the side edge of the tail lamp. The whole light will come off of the body in your hands. Once the tail lamp assembly is out there is an access panel on the back side where all the bulbs are installed. Depress the two holding tabs on the sides and carefully remove the bulb holder. Then replace any blown bulbs and reinstall.
