Yeah, I did check the battery, it seemed fine. But you mentioned computer system issues? What exactly was happening with yours?

Mine was throwing up random fault codes, and the ECU was intermittently unresponsive. Turned out to be undervoltage, triggering the memory lock. I'd suggest getting it checked by a workshop with proper ECU diagnostics tools.

Took it to a workshop. They diagnosed undervoltage causing an ECU fault and triggering the memory lock. ECU diagnostics and clearing the fault codes cost 240€. Sorted now, thanks for the help.

I had a similar problem with my Arona. Kept getting error messages, and the computer system was acting weird. Have you checked the battery voltage? That might be related to the memory lock issue.
