You might first notice this because your car will stall repeatedly, like when you tried to learn how to drive a stick shift. But if the air sensor fully kicks the bucket? Well, the car might idle rough and eventually stall. If it’s struggling, your car will have some performance issues. Here’s the deal with your mass airflow sensor. If you have a failing air flow sensor, your check engine light, which is kind of like a catch-all like, may illuminate. The warning lights are there for a reason and they’re positioned right in front of your line of sight, so you notice them.

Now I know you tend not to pay attention to the lights in your dashboard, but it’s never too late to start. It will also negatively impact your fuel efficiency. If the MAF is struggling, the readings may be off, and it won’t contribute to the mechanical symphony as it’s supposed to. The most common signs of bad mass air flow sensor (MAF) in VW Passat are loss of power or slow acceleration, engine hesitation or jerking during acceleration, erratic idling, misfires, poor exhaust emission values and sometimes black smoke comes out of the tailpipe. When you want to giddy up, but notice a lack of oomph, that could be a result of the air flow failing.

So, what exactly do you think happens when the MAF sensor kicks the bucket, and the car can’t make those adjustments? If you guessed that it’s no longer going to get the most out of its engine production, then congratulations, you’re totally right. So, the sensor detects how much air is making its way to the engine, so that the vehicle can make adjustments to the amount of air and get the most out of its engine production. Let’s see how much attention you’ve been paying. Symptoms of a failing Mass Air Flow Sensor
