Mercedes E Klasse Hybrid Brake Light Error

I drive a Mercedes, though not the same year or engine, and I had a similar brake light issue. My car showed an error, and the brake lights were acting up. It was a bad brake light switch. It's common in cars. Pressing the brake pedal too hard or too often can damage it. I'd check there first.

Thanks for the quick reply. Can you tell me more about checking the brake light switch?

I'm not an expert, but the switch is usually near the brake pedal. Unless you know what you're doing, messing with the brakes isn't a great idea. Brakes are important. I'd take it to a workshop. They can figure it out and replace the switch if needed. The automotive switch itself is not expensive.

I appreciate the advice. I found out I caused the problem. I accidentally turned off the tail lights in a setting. The error message is gone, and the brake system works now. The repair cost was 0€ Thanks again for your help.
