Citroen Nemo MAF Sensor Issue

I've got a 2015 Citroen Nemo diesel, with about 60k km on the clock. Recently, I've noticed higher fuel consumption and the engine sometimes stalls when idling. The check engine light is also on, and there's a bit of smoke when I accelerate. I suspect it might be the mass air flow meter (LMM) acting up. Anyone had similar experiences?

A 2015 Citroen Nemo diesel exhibited higher fuel consumption, engine stalling when idling, a check engine light, and smoke during acceleration. These symptoms suggested a potential issue with the mass air flow (MAF) sensor. After consulting with others who had similar experiences, it was advised to have the MAF sensor checked. A mechanic confirmed the MAF sensor was faulty, and replacing it resolved the issues.

Hey, sounds familiar! I had a similar issue with my old Opel Astra. Same symptoms: performance decline, check engine light on... Did you check the air intake for any obstructions?

Thanks for the reply. I glanced at the air intake, seemed okay at first sight. But what exactly should I be looking for?

Well, with my Astra it was a faulty MAF sensor. The garage confirmed that. Considering your symptoms, it points in a similar direction. I would suggest visiting a workshop to be sure.

Alright, thanks for the advice. I took it to a local mechanic, and it was indeed the LMM/MAF sensor. Cost me 365€ to replace. Runs smoothly now.
