Thanks, that's helpful. Where exactly should I be looking for electrical wiring issues? I'm not sure where to start.

Given it's an EV, poking around without proper training isn't wise; you could end up like a moth drawn to a flame. The error codes suggest a battery issue, and the power loss confirms that. I'd recommend taking it to a workshop and having them diagnose it professionally. Don't delay, as it could cause even more serious damage. I'm sure that's the battery pack which is failing.

Thanks for the advice. I took it to the shop, and they confirmed it was a battery problem. They replaced it, and the total cost was 290€. Everything is working fine now.

Sounds familiar. I had a similar experience with my Doblo – though mine is not electric. An electrical fault can manifest in all sorts of weird ways. Have you checked the electrical wiring for any obvious signs of damage or corrosion? It's like checking the pipes before calling a plumber.
