Zoe Intermittent Electrical Errors

I'm having an intermittent issue with my 2016 Renault Zoe (electric engine) with 234858 km. Sporadic errors appear in driving mode and various error lamps illuminate intermittently. System failures occur, primarily affecting audio/navigation. Control units temporarily shut down or become unresponsive. An error is stored in the error memory. Has anyone experienced similar issues or have any suggestions?

Sounds frustrating! I've seen similar gremlins in other electric vehicles. Have you tried checking the basics like the 12V battery health? A weak 12V can cause all sorts of weird issues with the electronics. Also, did you try to read out the error memory yourself?

Thank you for your reply. I have not checked the 12V battery specifically, but I will do so. Regarding the error memory, is there a particular scan tool you would recommend for the Zoe, or is a generic OBD-II scanner sufficient?

A generic OBD-II scanner should give you a code, but it might not be super specific for the Zoe's systems. Honestly, with those kinds of electrical gremlins, it's often a connector or wiring harness issue, especially with the audio/nav cutting out. I'd hate for you to chase ghosts and spend money on parts you don't need. I think you should visit a local garage and let them take a look.

I appreciate the advice. Based on your recommendation and further research, it appears the most likely cause is a defective cable connection to the BUS system. I brought the vehicle to a local workshop for diagnosis and repair. A defective cable connection of the control unit (connection to the BUS system) was indeed the root cause. Repair cost: 155€. Thank you again for your help.
