Movano Engine Stalling

My 2008 Renault Movano, diesel engine, with 87523 km has developed a fault. The check engine light is illuminated, and the engine stalls at idle intermittently. I suspect a tank ventilation valve malfunction. Has anyone experienced similar? I've visually inspected the hoses and they appear to have seen better days, potentially clogged.

I had a similar issue with my old Peugeot 307. Check engine light, rough idle, the works. Turned out to be a blocked EVAP system. Does your Movano have any trouble with refueling? That was another symptom I had.

Interesting. Refueling isn't particularly difficult, no fuel spitting back or anything obvious. I'll double-check the refueling behavior. If the hoses are indeed clogged, would replacing them solve the issue, or is there more to the EVAP system I should consider?

Replacing the hoses might help, especially if they're visibly degraded, it is worth trying as a first step. But blockage could be elsewhere in the system too. Based on my experience, you would need to check for leakages. Seeing that the ventilation valve is faulty, you might need to get it checked at the workshop to properly diagnose. Keep me posted.

Thanks for the input. Ended up taking it to a workshop, as suggested. Faulty tank ventilation valve and, as suspected, the hoses were clogged. New valve and hoses, cleared the code. Total cost was 175€, runs like a charm now.
