Skoda Praktik High Fuel Consumption and Engine Stalling

I am writing to seek assistance regarding a perplexing issue with my 2009 Skoda Praktik, which has a gasoline engine. The vehicle has accumulated 214121 km. Recently, I've observed a rather concerning set of symptoms, namely a higher fuel consumption than usual. Furthermore, the engine stalls unexpectedly when idling, which is quite alarming. The check engine light has illuminated on the dashboard, and I've also noticed smoke emanating from the exhaust during acceleration. I suspect the mass air flow meter (LMM) may be defective and causing a sensor failure. Could this be the reason?

A 2009 Skoda Praktik with a gasoline engine is experiencing high fuel consumption, unexpected engine stalling, and smoke from the exhaust, with the check engine light on. These symptoms suggest a potential issue with the mass air flow (MAF) sensor, which may be defective and causing incorrect air intake readings. Cleaning the MAF sensor could be a temporary fix, but replacement is recommended if faulty. After replacing the MAF sensor, the engine performance improved, resolving the issues.

Did this summary help you solve your problem?

Sounds like a MAF sensor issue for sure. I had similar problems with my old Renault Megane – higher fuel consumption, the engine stalling at idle sometimes, and the check engine light lit up. Replacing the MAF sensor fixed it. Have you tried cleaning the MAF sensor first? Sometimes that helps, although it might be a temporary fix. Also, does the car hesitate or feel sluggish when accelerating?

Thanks for the quick reply! Cleaning the MAF sensor is something I haven't tried yet. Where is the MAF sensor located, and is it easy to get to? And yes, I've noticed a performance decline, especially when trying to accelerate quickly. Is that another sign of a MAF sensor failure?

The performance decline definitely points towards the MAF sensor. Think of it like this: the engine isn't getting the right information about how much air is coming in, so it messes up the fuel mixture. As for location, it's usually somewhere in the intake system, between the air filter box and the throttle body. You should be able to find videos online that show exactly where it is on your Skoda. Cleaning it might help temporarily, but if it's actually faulty, replacement is the only real solution. Given all the symptoms you're describing, and especially the smoke, it's probably best to get it checked by a workshop.

Took the Skoda to the workshop, and you were spot on. The MAF sensor was causing all the trouble. They replaced it, and after everything, including labor, it came to 365€. Now the engine runs smoothly again. Thanks a bunch for your help!
