How to Change the Brake Lights on an Audi
1. Open the trunk and pull back the carpet in the cargo luggage area.
2. Locate the nuts holding the brake light housing cover. Remove these nuts with a socket wrench.
3. Remove the housing cover and disconnect the electrical wiring from the bulb housing.
4. Turn the bulb counterclockwise to unlock it from the housing. Pull the bulb straight out of the housing.
5. Install the new bulb, reassemble the housing and replace the carpet in the trunk. Installation is the reverse of removal.
