I did verify the fuses, and they appear to be in good order. Could you elaborate on the specifics of the issue you experienced with your Renault Megane? Any further details regarding the troubleshooting steps you undertook would be greatly appreciated.

Sure thing! With my Megane, it turned out to be a faulty headlight switch, but it took ages to figure out. I tried replacing bulbs, checking the wiring I could easily get to, but nothing worked. In the end, I took it to a garage. I think you may need a professional to get it fixed properly.

I appreciate you sharing your experience; it has been most insightful. Following your recommendation, I shall consult with a qualified technician to perform a comprehensive diagnostic assessment and effect the necessary repairs. The invoice totaled 95€.

Hey, that sounds frustrating! I had a similar weird electrical problem with my old Renault Megane. The dashboard lights would flicker and sometimes the headlights would just pop on. Did you check the fuses? Sometimes a blown fuse can cause strange stuff to happen.
