C30 Brake Light Failure

I've had similar issues with my C30, although I don't recall the exact error code. Does the error occur consistently, or does it seem to happen more often under specific circumstances, like after driving for a while or during cold weather?

It's pretty random, to be honest. Sometimes it happens right away, sometimes after an hour of driving. Weather doesn't seem to matter. Could it be a faulty sensor or something?

Given the inconsistency and the fact that it's logging a brake light switch fault, I would suggest having it checked by a qualified technician. A failing brake light switch can indeed cause intermittent issues. While it might be a simple sensor replacement, it's best to get a professional diagnosis to ensure proper vehicle safety.

Thanks for the advice! Turns out, after a closer look, a floor mat had slid forward and was ever-so-slightly pressing on the brake pedal. Problem solved, and it cost me nothing!
