Peugeot 408 ECU Reflash Needed

My 2022 Peugeot 408 hybrid is acting up. Only 40k km and the diagnostics say faulty vehicle software. Error codes stored, general electrical malfunction, and the nav system is dead. Could it be an ECU problem? Has anyone seen this kind of control module issue?

Sounds rough. Could be a software bug. Did anything specific happen right before these problems? Any recent work done?

Nothing out of the ordinary. Just started up one morning and boom, errors. "Programming of the control unit implausible" is the error code. Any ideas?

"Implausible programming of the control unit"? That points to the ECU. Get it to a workshop to get that checked, before it fries something.

Took your advice and brought it in. The control unit needed a reflash. Cost me 240€, but at least it's sorted.
