Skoda Fabia Engine Issues

My 2007 Skoda Fabia with a gasoline engine is exhibiting some concerning symptoms at 225488 km. The check engine light is on, fuel consumption has increased noticeably, and there's a loud hissing sound when accelerating. Could this be an air intake system leak?

Sounds like a vacuum leak. I had similar symptoms in my Fabia: check engine light, hissing sound, and terrible fuel economy. Did you inspect the intake hose between the air filter box and the intake manifold?

Intake hose specifically? Is that a common failure point? Where exactly should I be looking for the leak? I'm not sure how to perform leak detection.

Yes, the intake hose is a known weak spot. Cracks often develop over time. If you're not comfortable diagnosing it yourself, I would recommend taking it to a trusted workshop. They'll perform a smoke test and pinpoint the leak quickly.

Confirmed. The intake hose had a significant split. Replacement cost about 100€. Fuel economy is already improving. Thanks for the advice.
