Could you be more specific about which circuit breakers and fuses I should check? I don't want to start pulling things out randomly and cause more damage. Any guidance?

I can't recall the exact fuse number. However, based on the error and symptoms, I'd recommend having a workshop check the cable or plug connections, as that's likely the cause. It cost me 95€ to get it fixed.

Thanks for sharing your experience. I took your advice and brought the car to my mechanic. You were spot on – it was a faulty connection in the ignition switch wiring. They replaced the connector, and it's running smoothly again. Thanks again for pointing me in the right direction!

I had a similar issue with my LX. Check the ignition switch; a faulty connection there can cause this. Have you checked the circuit breakers and fuses related to the power supply? It might be a simple fix.
