Skoda Kodiaq Diesel Performance Problems

Alright, I'm experiencing some issues with my 2017 Skoda Kodiaq diesel, and I'm hoping someone can offer some insight. It's got 137372 km on the clock. Lately, I've noticed a significant performance decline. Fuel consumption is way up, and the engine occasionally stalls at idle. Plus, the check engine light is now illuminated, and there's some smoke when I accelerate. From what I've read, it sounds like a defective mass air flow meter (LMM). Could a defective mass air flow sensor be the cause?

Whoa, sounds familiar! I had almost the exact same symptoms with my old BMW 3 Series – higher fuel consumption, engine stalling, and that dreaded check engine light. Definitely sounds like a mass air flow (MAF) sensor issue. Did you check the air filter? A dirty air filter can sometimes gunk up the MAF sensor.

Interesting. When you say 'gunk up' the MAF sensor, what exactly happens? Is it something I could have prevented with more frequent air filter changes, or is it just a matter of time before the sensor fails?

Yeah, 'gunk up' means the sensor's hot wire gets coated with dirt and oil from the air intake. This messes with its ability to accurately measure the air flow. More frequent air filter changes can definitely help prevent it, but sometimes they just fail. Given all your symptoms, I'd say it's time to visit a workshop.

Took it to the shop, and you were spot on. The mass air flow sensor was indeed the culprit. New sensor installed, total cost 365€. Runs like a champ now. Thanks a bunch for your help!
