S80 Engine Stalling at Idle

Hello, I'm experiencing an issue with my 2016 Volvo S80 diesel. It has about 149250 km on it. The check engine light keeps coming on, and the engine occasionally stalls at idle. I suspect it might be the tank ventilation valve. Could clogged hoses be the cause? Any ideas?

A 2016 Volvo S80 diesel with 149,250 km is experiencing engine stalling at idle and a persistent check engine light. The suspected cause is a tank ventilation issue, possibly due to clogged hoses. A suggestion to check the gas cap and purge valve was made, leading to the discovery of clogged hoses, which were repaired at a workshop.

Hey, I had something similar happen with my S80. Check your gas cap and the purge valve. Is it hard to open the gas cap, like there's a vacuum?

Thanks for the quick reply. I'll check the gas cap. Where exactly is the purge valve located, and is there a way to check if it's working correctly?

It's near the engine, part of the emission system. Honestly, it's a pain to get to. If the gas cap is acting weird, and the light's still on, I'd just take it to a workshop. Save yourself the headache.

Thanks for the advice! I took it to a workshop, and you were right, it was a ventilation issue. Turns out the hoses were indeed clogged, as I suspected. The repair cost 175€. Appreciate the help!
