Ccrosser Engine Stalling

I've got a 2011 Citroen Ccrosser diesel with 176465 km. The check engine light is on and it sometimes stalls at idle. I think it's a fuel tank ventilation leak, maybe the charcoal filter. Does that sound right, and what should I check before taking it to a shop?

I had the same problem with my Ccrosser. Check engine light and stalling, especially when the fuel level was low. Sounds like your charcoal canister is shot. Is it also struggling to get airflow when you remove the fuel cap?

I haven't checked the airflow when removing the fuel cap, but I do hear a slight hissing sound. Could that indicate a pressure issue?

Yes, the hissing is definitely a symptom. Mine got progressively worse. Honestly, at that mileage, I'd just replace the charcoal filter/canister. However, it's an emission control part, so a leak there could affect other sensors. It's best to get it properly diagnosed at a workshop before throwing parts at it. Cost me around 275€ to get fixed.

Thanks, I'll get it professionally diagnosed to avoid problems with other systems. The cost estimate is helpful.
