C2 Terminal 15 ignition problem

Hey, I had a similar issue with my C2 some time ago. The 'Terminal 15' thing sounds like a circuit break. Have you checked the battery terminals for corrosion or voltage drop? That was the cause of it for me.

Thanks for the info! Corrosion is a good point, I'll check that. When you say 'circuit break', do you mean like a literal broken wire somewhere?

Yeah, a broken wire or a faulty plug connection. But since the error message points to Terminal 15, it is probably the cable or plug connection. To be honest, I'd recommend getting it checked at a workshop. It cost me around 100€ back then.

Thanks a lot! I'll check the connections and maybe bring it to a workshop as you suggested. It turned out to be a defective plug that cost me 95€!
