How to fix the Audi A2 brake lights?

I recently noticed that my Audi A2's brake lights are not working properly. They sometimes turn on and off randomly, and it's causing some safety concerns while driving. I want to fix this issue myself, but I'm not sure where to start. Can anyone provide some guidance on how to properly diagnose and fix the brake light issue on an Audi A2?

First, check the fuse for the brake lights. If it's blown, replace it and see if that solves the issue. If not, you may need to check the brake light switch and wiring for any damage or loose connections.

I had a similar issue with my A2 and it turned out to be a faulty brake light assembly. Check the bulbs and the wiring connections to the assembly. You may need to replace the entire assembly if it's damaged.

Before replacing any parts, make sure to also check the brake pedal position switch. It's responsible for activating the brake lights when you step on the pedal. If it's malfunctioning, it can cause issues with the brake lights.
