Peugeot 307 MAF Sensor Issue

My 2009 Peugeot 307 diesel is nearing 300k kilometers. I'm seeing higher fuel consumption, engine stalls sometimes at idle, the check engine light is on, and there's a bit of smoke when accelerating. Suspect the mass air flow meter. Anyone else experienced similar?

Sounds like MAF sensor failure, yeah. Is it affecting your car's air-fuel ratio? Is your performance decreasing as well?

Decreasing performance, certainly, but how would I concretely check the air-fuel ratio without diagnostic tools? Any thoughts?

That's tricky without the right gear, isn't it? Considering the symptoms and mileage, and given how crucial the MAF is for optimal combustion, a garage visit might be wise to confirm.

Garage confirmed the MAF sensor was shot. 365€ later, it's sorted. Thanks for pointing me in the right direction.
