DS4 Brake Light Error

I've got a DS4 and that sounds vaguely familiar. Was the error message specifically related to the braking system or something more generic? Did you check the simple things, like the bulbs themselves?

The error message is about the braking system, saying there's a potential fault with the brake light circuit. The bulbs are good, even after replacing them. I'm thinking it's the brake light switch. Does that match your experience?

Ah, okay, that's it exactly! The brake light switch went bad in mine too. Same symptoms – error message, lights not working. I was stumped for a bit. Ended up having the shop take a look. They replaced the switch; simple fix.

Thanks for confirming. I checked the switch and it was misadjusted from the previous install. Easy fix. The brake lights work now, and the error is gone. Repair cost: 0€
