Peugeot 301 Engine Stalling
Summary of the thread
A 2020 Peugeot 301 diesel is experiencing engine stalling, particularly at idle, with the check engine light on. The suspected cause is a tank ventilation valve issue, possibly due to clogged hoses. It is advised to have a professional mechanic inspect and address the problem, as the emission system can be complex and sensitive. The user confirmed that clogged hoses were indeed the issue, and the problem was resolved by a mechanic.

Thanks. The stalling is random, not after refueling. It happens intermittently at idle, no matter the fuel level. Given your Opel experience, could I fix it myself, or should I go to a workshop?

Given the random nature, and that you already suspect the ventilation valve, that's likely it. I'd recommend a workshop. The emission system is finicky. I made things worse trying to fix my Opel myself.

Appreciated. I'll book my local mechanic to check the tank ventilation valve thoroughly. Seems my initial thought was close. They found the hoses clogged as I suspected. Final bill was 175€. Thanks again for sharing your experience; it was invaluable!

I had a similar issue with my old Opel: check engine light and stalling. It was also fuel tank ventilation. Those systems are sensitive. Does it stall predictably, like after refueling, or is it random?
