N400 Intermittent Fault
Summary of the thread
A 2015 Chevrolet N400 with a gasoline engine is experiencing intermittent faults, including sporadic errors in driving mode, illuminated error lamps, and occasional system failures, particularly affecting audio/navigation. The issue is traced to a defective cable connection of the control unit, specifically its connection to the BUS system. The recommended solution is to have a workshop inspect and repair the faulty connection, which resolved the problem.

Cable connections to which control unit specifically? The errors are varied, making it difficult to pinpoint a single area of the system.

Yeah, that sounds like what I had, alright. It's the cable connection of the control unit, specifically its connection to the BUS system. Honestly, with that many systems acting up, I'd recommend a workshop look. My local shop found the defective connection pretty quickly.

Thank you for the advice. I had the vehicle inspected, and the defective cable connection of the control unit (connection to the BUS system) was indeed the problem. Repair cost was 155€.

Sounds familiar! I have an N400 too and had similar issues. Random lights, radio cutting out, the whole shebang. Did you happen to check the cable connections? I'm wondering if that might be the culprit. Where exactly are you seeing the errors pop up?
