308 Rearview Mirror Heating Issue

I had something similar with my 308. Rearview mirror heating packed up. Same symptoms, error code and all. I suspect a dodgy connection somewhere.

Interesting. Where exactly was the dodgy connection? Did you manage to fix it yourself, or did you need to take it somewhere?

Didn't fix it myself. Just took it to the workshop. They said it was likely the cable or plug connection. Worth getting it checked out professionally. Will save you some headaches!

Cheers for the advice. Took it to the shop as you suggested. Turns out you were spot on, it was a loose connection. Cost me 95€ to sort. Appreciate the help!
