Skoda Fabia Air Valve Issue

My 2022 Skoda Fabia with a gasoline engine is throwing a check engine light. Diagnostics point to an air valve issue, specifically a problem with the air supply. I suspect a defective hose connection from the pump to the valve. Has anyone else experienced similar issues with the air valve system on these cars? I'm seeing some minor idle problems as well. Any insights before I start tearing things apart looking for vacuum hoses?

I had a similar issue with my Fabia. Check the vacuum hoses connected to the air valve. A leak there can definitely trigger the check engine light and cause idle problems.

Interesting. Could you be more specific about which vacuum hoses? Was it obvious, like a split hose, or something more subtle? And did you also experience any rough idling?

Yes, rough idling was present. It was indeed the vacuum hoses. I didn't spot the exact location, but the mechanic pointed out that the connection from pump to valve was defective. I'd recommend a visit to a workshop; they will be able to locate the fault much faster.

Took the Fabia to the workshop. It was exactly as suspected, a faulty hose connection on the air valve. They replaced the vacuum hoses and ran diagnostics. Total cost was 175€. Check engine light is off and the idle problems are gone. Thanks for the confirmation!
