Skoda Octavia Engine Issues

I come seeking wisdom. My 2019 Skoda Octavia, gasoline engine, with 246014 km on the clock, is exhibiting concerning symptoms. Specifically, I'm experiencing higher than usual fuel consumption, the engine stalls intermittently at idle, the check engine light has illuminated, and, most alarmingly, there's visible smoke upon acceleration. Preliminary diagnostics suggest a defective mass air flow meter (LMM). Could this be the root cause? I understand the LMM's role in regulating the air intake and influencing the air-fuel ratio, but I'm keen to hear opinions before committing to a replacement.

High fuel consumption, stalling, check engine light and smoke? Sounds like a classic case of sensor failure messing with your air-fuel ratio. First, have you checked your air filter? A clogged filter can sometimes mimic MAF sensor issues. Also, are you sure the sensor connector is properly seated?

Thanks for the reply. Air filter is clean, replaced it recently. The connector seems secure. But how exactly does a faulty MAF sensor cause smoke on acceleration? I'm trying to understand the underlying mechanics here.

Think of it like this: the MAF sensor tells the engine's computer how much air is coming in. If it's lying, the computer miscalculates the fuel needed. Too much fuel leads to incomplete combustion, hence the smoke. Since you've checked the obvious, and the symptoms are pointing that way, a faulty MAF sensor is very probable. It's best to get it properly diagnosed at a workshop to confirm, though.

I appreciate the insights. Took it to a trusted mechanic, and you were spot on. MAF sensor was indeed the culprit. New sensor installed, bill came to 365€. Runs like a champ again. Thanks!
