S80 Engine Stalling At Idle

My 2007 Volvo S80 (gasoline engine) is stalling at idle and the check engine light is on. There's also an error stored in the memory. I suspect a contaminated intake affecting the IAC valve. Anyone else experience this?

A 2007 Volvo S80 is experiencing engine stalling at idle, accompanied by a persistent check engine light and an error code. The suspected cause is a contaminated intake affecting the Idle Air Control (IAC) valve. A workshop confirmed the issue, identifying a faulty IAC valve and a heavily contaminated intake, and the repair was completed to address the problem.

I had similar stalling issues with my old Renault Megane. Turned out to be some valve thing too. Was the check engine light always on?

Yes, the check engine light is always on. What valve issue did your Renault have? Was it also an IAC valve, and did it happen primarily at idle?

Can't recall exactly, but the garage guys mentioned idle speed and some air thing. Best to just get it checked out by a professional.

A workshop confirmed a faulty IAC valve and a heavily contaminated intake. Repair cost 425€. Hopefully, that fixes it.
