How to Replace the Brake Light Bulbs on an Audi A3 Sportback?

Model: Audi A3 Sportback MK 3 - Years 2012-2019
Part: Light bulb

To replace the brake light bulb on the Audi A3 Sportback, first obtain replacement W21W bulbs. Go to the boot and start by removing the side trim on the side you will be working on. Behind this trim, there is a cubic plastic nut; unscrew it using a screwdriver inserted into the holes on either side of the nut. The next step is to remove the rear light from its housing; you will need a flat tool, preferably plastic, to avoid damaging the paint. Insert it into the gap between the light and the bodywork and lever it out, as shown in the video. Then disconnect the connector and finally remove the base where the bulbs are located.
