Eon sporadic errors and control unit shutdown

I had similar symptoms with my Eon. It sounds like your car is acting like a faulty electrical outlet in your home. Just like an outlet that's not properly connected can cause lights to flicker or appliances to malfunction, a loose or corroded connection in your car's wiring harness can cause all sorts of weird electrical gremlins. Was the problem you experienced also in the area of audio/navigation?

Yes, that's right. The audio/navigation system is definitely affected. So, you're saying it was also something related to the wiring? Any more details on which connection it was specifically and the steps you took?

I understand your concern. In my case, it turned out to be an intermittent connection issue. Because modern cars are becoming computers on wheels I would suggest going to a reliable workshop. They have the tools to check all the electrical connections to the BUS system. It's better to be safe than sorry.

Thanks for the insights! I appreciate you sharing your experience. I'll take it to a workshop and have them check the BUS system connections, as you suggested. Hopefully, it's a similar fix and not something more complicated. The workshop found out that the cable connection of the control unit was defective, exactly the connection to the BUS system, as suspected. Repair cost: 155€.
