Peugeot 406 Sporadic Errors
Summary of the thread
The conversation centers on sporadic errors in a 2002 Peugeot 406, including intermittent warning lights, audio/navigation failures, and control unit shutdowns. The suspected cause is a defective cable connection to the BUS system, as indicated by stored error codes related to communication errors within the CAN bus network. A similar issue was resolved by addressing a corroded connector in the wiring harness, and the recommendation is to consult a qualified technician for a thorough inspection and repair.

Yes, I have utilized an OBD-II scanner, and several codes related to communication errors within the CAN bus network are present. Could you elaborate on the specific nature of the cable connection fault you encountered and perhaps indicate which control units were primarily affected in your case?

Certainly. In my case, it was ultimately a corroded connector within the wiring harness that serves the central control module. While my specific symptoms mirrored yours, pinpointing the exact source required a thorough inspection by a qualified technician. Given the potential complexity and the importance of the affected systems, I would strongly advise consulting with a competent automotive workshop equipped with the necessary diagnostic tools and expertise.

I appreciate your detailed explanation and prudent advice. Based on your experience, I will proceed with scheduling a diagnostic appointment at a reputable workshop. I received a quote of 155€ for the repair, so with some luck, it will resolve the error. Thank you again for sharing your insights; your contribution has been invaluable.

Interesting. I have a 406 and I experienced very similar issues a while back. The symptoms you describe – sporadic errors, system failures, and unresponsive control units – all align with what I encountered. Did you check the OBD-II port for specific error codes?
