As a Volkswagen owner, you know that your car is equipped with a Mass Airflow Sensor (MAS) to help ensure optimal engine performance. You’ll want to know what happens if this vital component starts to fail, and one of the most common symptoms of a mass airflow sensor failure is when the check engine light comes on.

The check engine light is often the first indicator that something is amiss with your vehicle. It may be caused by something as simple as a loose gas cap, but in many cases it can be an indication of a more complicated issue, such as a mass airflow sensor failure. In this case, you should contact our qualified mechanic right away to diagnose the problem and repair any necessary components. Ignoring the check engine light can lead to further damage, or even complete engine failure, so be sure to do the right thing and address any concerns promptly. Let’s look at other telltale signs of a mass airflow sensor failure.

Your VW is Stalling or Running Rough

If your VW is starting to stall or run rough, it could be a sign that the mass airflow sensor needs to be replaced. It is important to address this issue as soon as possible, in order to avoid more costly damages down the line. Replacing the sensor involves not only knowledge of where to place and how to connect it, but a precision when doing so. If the task seems daunting, consult our certified VW mechanics at Glenwood Foreign Car. With our expertise and experience, we can diagnose and resolve the issue quickly. Don’t let your car’s performance suffer!

Poor Fuel Economy

Another symptom of a mass airflow sensor failure is poor fuel economy. This vital engine component influences the air-to-fuel ratio, which in turn affects fuel combustion efficiency. In short, when the mass airflow sensor isn’t working properly, your vehicle consumes more gasoline than it should and you can expect to see a noticeable decrease in gas mileage.

It is recommended that any suspected problems with your vehicle’s mass airflow sensor be checked out immediately by our trained technician for swift resolution before any further damage occurs.

Your VW is Hesitating or Surging

If your car isn’t accelerating smoothly and instead seems to hesitate or surge within speed, it may be an early warning sign of a failing mass airflow sensor. A MAF sensor measures intake air volume for fuel adjustments, so when it fails or is performing poorly, your Volkswagen’s performance will suffer from issues with acceleration, power, and idle.

Even worse, a damaged MAF sensor can cause fouled spark plugs, or even inhibit the vehicle from starting. It’s important to diagnose this problem as soon as possible in order to avoid other damage that can occur if left unchecked.

Black Smoke from the Exhaust Pipe

Black smoke coming from the exhaust pipe is never a good sign, and can point towards larger engine problems. One of the biggest issues that black smoke signifies is an issue with the mass airflow sensor. This component detects air intake while the car is running and helps regulate engine performance, so any malfunction here can be disastrous.

Replacing or fixing this sensor quickly is essential to prevent serious damage elsewhere in the engine, so if you experience any black smoke from your exhaust pipe it’s advisable to get the problem checked out by our mechanics as soon as possible.
