Twingo engine stalls at idle

I have a 2014 Renault Twingo with a gasoline engine, mileage is at 149694 km. The check engine light illuminated, and the engine stalls at idle. I suspect a tank ventilation valve malfunction due to clogged hoses. Has anyone experienced this?

Sounds familiar. Had similar symptoms on my old Opel Corsa a few years back. Check engine light and idling issues. Was also related to the fuel tank purge valve. Did you check for any obvious cracks or disconnections in the hoses?

Yes, I visually inspected the hoses. Couldn't spot any cracks. But how did you determine it was definitely the purge valve on your Corsa? Any specific tests you ran?

I didn't have the tools for proper diagnostics, to be honest. My mechanic used a smoke test to find a leak in the emission system, pointing to the valve. Based on my experience, and the cost involved, I suggest a visit to the workshop.

Thanks for the advice. Took it to a mechanic, and it was indeed the tank ventilation valve. Hoses were clogged. Repair cost me 175€. Appreciate the help!
