Megane Electric won't start

I'm having a weird issue with my 2022 Renault Megane Electric. The car won't start, and the error memory shows 'Terminal 15 ignition positive interrupted'. I've checked the obvious stuff – battery voltage seems fine, but I suspect it might be related to a defective cable or plug connection. Mileage is at 237086 km. Has anyone experienced something similar? I'm thinking maybe a fuse box issue, voltage drop somewhere, or even a faulty relay switch affecting the starter solenoid.

I had a similar problem with my Megane, although it wasn't the electric version. Check the connections to the fuse box in the engine compartment; those can corrode and cause intermittent issues like you're describing.

Thanks for the tip! Which specific connection in the fuse box did you have problems with? Was it visibly corroded, or did you have to test for voltage drop to find it?

Honestly, I didn't dig that deep myself. After a bit of poking around, I decided it was beyond my capabilities and took it to a workshop. But the symptoms sound very similar to what I experienced.

Took it to the shop. It was indeed a defective plug connection, just as the error code suggested. Repair cost me 95€ Thanks for the advice!
