Peugeot 301 brake light failure
Summary of the thread
A 2016 Peugeot 301 experienced a brake light failure, indicated by an error message on the infotainment system and stored in the error memory. The issue was suspected to be related to a simple fuse or similar component. Upon further investigation, it was identified as a problem with the brake light switch, which was not being fully engaged due to the brake pedal not returning completely. A quick adjustment of the pedal resolved the issue without any cost.

Interesting. No, I haven't checked if the error disappears when pressing the brake pedal. Where is the brake light switch located exactly? And is it something I can replace myself without special tools?

It's usually located near the top of the brake pedal. While you might be able to replace it yourself, I'd recommend taking it to a workshop. Could be a faulty replacement.

Thanks! I went to the workshop. Turns out it was the brake light switch indeed, and the error was logged because the pedal wasn't fully returning and pushing the switch. They adjusted the pedal, and now it's working perfectly. No cost, just a quick adjustment!

I had a similar problem with my old Volvo. It turned out to be the brake light switch. Did you check if the error disappears when you depress the brake pedal?
