GLK Brake Light Error Memory Full

I had something similar in my GLK. A tail light malfunction warning kept appearing. Have you checked the brake pedal itself? Something might be stopping it from moving fully.

Interesting. What do you mean by something interfering? Is something physically blocking the brake pedal?

Yes, that's what I meant. For me, the floor mat was bunching up a little. It wasn't obvious at first. If the pedal is clear, it could be the brake switch itself. A workshop visit might be a good idea.

Thanks for the tip! You were right. The floor mat was the problem. I moved it, and the error is gone. The error memory had a lot of brake switch errors, but it's clear now. The brake system is working properly again. I appreciate the help!
