Mondeo Hybrid Driving Mode Errors

I'm having sporadic errors in driving mode and intermittent error lamps in my 2019 Ford Mondeo Hybrid with 159810 km. Various systems, especially audio/navigation, are failing. Sometimes control units shut down. A scan tool shows errors. Anyone seen this?

Sounds like a frustrating gremlin. The flickering errors and system failures remind me of a loose wire. Have you checked the main wiring harnesses and grounding points for corrosion or looseness? A faulty connection can cause havoc.

Thanks, but my expertise is limited. Could you elaborate on the location of these wiring harnesses and grounding points, especially related to the control units? Are there specific diagnostic procedures beyond a visual inspection?

Tracing electrical faults without tools and knowledge can be tough. Given the intermittent nature, affected systems, and error codes, consulting a workshop is best. It could be a defective cable connection to the BUS system. They can pinpoint it with specialized equipment.

I took it to a local workshop, and they confirmed the cable connection fault. The repair cost 155€ and fixed the issue. Thanks for the guidance.
