Peugeot 508 Brake Light Error

Hey, I've got a 2019 Peugeot 508 diesel, and I'm seeing some weird stuff. The brake lights are acting up, and I'm getting an error on the dash. Hooked it up to a reader and there's an error stored relating to the brake light switch. Anyone else had this?

A 2019 Peugeot 508 owner experienced a brake light error on the dashboard, with a diagnostic reader indicating an issue with the brake light switch. Initial suggestions included checking the bulbs and considering recent electrical work. The problem was resolved when a mechanic identified that the cruise control's brake override function had been inadvertently triggered, and resetting the system fixed the issue without any cost.

Could be a faulty switch, but those usually just fail outright. Did you check the bulbs themselves? Sometimes a bad bulb can throw a code. Also, any recent work done on the car's electrical system?

Bulbs are fine. Nothing done recently, just normal driving. If it was the switch, would it just be a straight replacement or is there some coding involved?

Given it's a 2019, it probably needs coding to the car's computer. If it was my car, I would take it to a workshop to get it checked out.

Turns out, after taking it to a workshop, I had inadvertently triggered the cruise control's brake override function somehow. The mechanic reset the system, and everything is back to normal. No cost to me.
