Renault Wind MAF sensor issue

Hi, I'm having trouble with my 2011 Renault Wind (gasoline engine) with 206,000 km. I've noticed increased fuel consumption, and the engine occasionally stalls when idling. The check engine light is on, and I saw some smoke when accelerating. I suspect a defective mass air flow meter (LMM). Anyone experienced similar issues?

I had something similar happen with my Wind. Higher fuel consumption, check engine light, and sluggish performance. Did you check your air filter? A dirty air filter can mess with the air-fuel ratio, which then affects the mass air flow readings.

Thanks for the tip! I haven't checked the air filter yet. So, if the air filter is dirty, it can cause the mass air flow sensor to give incorrect readings, leading to the check engine light and other symptoms?

Exactly. A clogged filter restricts airflow. If it’s not the filter, it might be the MAF sensor itself. From what you describe, it’s probably the sensor. I ended up going to a workshop to have it diagnosed and replaced.

Thanks, that’s helpful! I'll start by checking the air filter. If that doesn't solve the problem, I'll take it to a workshop and have them check the mass air flow sensor. I will post what I find. It turned out the MAF sensor was indeed faulty. The repair cost me 365€.
