XC60 Engine Stalling at Idle

I'm having issues with my 2018 Volvo XC60 diesel. The check engine light comes on intermittently, and occasionally, the engine stalls at idle. I've got 141668 km on the clock. I've checked the gas cap, and it seems fine. Could this be related to the fuel tank ventilation valve?

Sounds familiar. I had a similar issue with my XC60. Check the hoses connected to the tank ventilation valve; they're prone to getting clogged, especially with a bit of age on them. Any DTC codes?

Thanks for the suggestion! Clogged hoses sounds plausible. I haven't checked the DTC codes yet. Where exactly are these hoses located, and is it a straightforward job to inspect them?

They're part of the EVAP system, near the fuel tank. It's doable to inspect, but access can be a pain without a lift. Honestly, if you're not comfortable, a workshop is your best bet. Faulty purge valve can trigger those symptoms, too.

Appreciate the confirmation! I took it to my local mechanic, and you were spot on. The hoses were indeed clogged, causing the ventilation issues. They cleaned everything out, and the engine runs perfectly again. Total cost was 175€.
