Megane hybrid power loss after chip tuning

I own a Renault Megane as well. I seem to recall encountering a similar problem. Could you clarify which fault code your scan tool is reporting?

Thanks for the quick response. I'm not very technical and didn't write the fault code down. Is there any way to further pinpoint the error without the exact fault code?

Based on your description, it does sound suspiciously like the issue I faced. Given that you had chip tuning performed, and the symptoms align with potential ECU problems, I would strongly advise having it inspected by a qualified workshop.

Thanks for confirming my suspicions and the advice. I took it to the workshop, and it turns out that the chip tuning was indeed the culprit. They re-flashed the ECU, and it cost me 180€ Appreciate the help!
