Mobilio electrical fault
Summary of the thread
A 2017 Honda Mobilio diesel is experiencing electrical issues, with diagnostics revealing an error related to the control module's programming. The problem is suspected to be a software glitch in the ECU, possibly requiring a software refresh or reset. It is advised to have a professional handle the re-flashing of the control module, as generic OBD2 readers may not suffice. The vehicle has been booked into a workshop for a software re-flash to resolve the issue.

No recent work done, just regular servicing. I don't have the specific error code to hand. I'm not sure if a software refresh is something I can handle myself, or if it needs specialist tools. Is this something that a generic OBD2 reader can address or am I facing a trip to the shop?

Without the code it's hard to say for sure, but based on the symptoms, a generic OBD2 reader probably won't cut it. These newer ECUs often require specialized programming tools. The 'implausible programming' message is a pretty strong indicator you'll need a pro to re-flash the control module. Best to get it checked before it causes further electrical gremlins.

Thanks for the advice. Booked it in at the workshop. They've confirmed it's a software glitch and are quoting 240€ for a re-flash. Appreciate the help!

Sounds like a classic case of corrupted ECU software. Has the car had any recent work done, like a battery change or any other electrical fiddling? A glitch could easily scramble the maps. You might need a software refresh, or even a complete software reset. Do you know the specific error code?
