Peugeot 308 control unit programming implausible

Experiencing bizarre issues with my 2022 Peugeot 308 hybrid. At only 12282 km, it's throwing errors and I'm getting general electrical malfunctions. The navigation system is completely non-functional. Onboard diagnostics say the programming of the control unit is implausible. Anyone else run into similar vehicle software faults? Trying to avoid a costly trip to the dealership if possible, but it's looking like a software reset or reflash might be necessary. I hate ECU problems like this.

Sounds familiar. I had a similar experience with my 2019 Volvo XC60. Random electrical gremlins and a useless infotainment system. Did the diagnostics point specifically to the control unit?

Yes, the onboard diagnostics definitely points towards the control unit being the culprit, specifically an issue with its programming. It seems like the errors all stem from there. Was your Volvo also pointing to a control unit issue or something else?

Confirmed, my issue was traced back to the ECU as well. Unfortunately, there wasn't anything I could do myself. Best bet is to get it to the workshop; they'll likely need to re-flash the control unit.

Thanks for the confirmation and advice. I was hoping to avoid it, but it sounds like a workshop visit is inevitable. I went to the shop and they said the same: programming of the control unit was implausible. Cost me 240€ to fix. Appreciate the help!
