Traveller Electrical Malfunctions

I have the same Traveller model, and this sounds very familiar. I had similar symptoms – error messages, random electrical glitches, and the navigation cutting out. It's a pain. Does it happen more often in certain conditions, like after a software installation or a period of inactivity?

Thanks. Yes, it started happening soon after the last scheduled maintenance. Can I solve this myself, or should I leave it to professionals? I am not very experienced with auto repairs.

Given that it started after the maintenance and involves the ECU, I would advise against a DIY fix. Incorrectly flashing or resetting the ECU can cause more harm. Take it back to a qualified workshop, explain the symptoms, and mention a possible software issue related to the recent maintenance. They should be able to recalibrate or reset the control unit.

I appreciate the advice. I have scheduled an appointment with a certified Peugeot service center to address the software issue. They quoted me around 240€ for the recalibration. Hopefully, this will resolve the electrical gremlins. Thanks again!
