If you are concerned that the Mass AirFlow (MAF) sensor is failing in your vehicle, you want to understand why this happened. The mass airflow sensor is a part of your car’s electronic fuel injection system. The MAF measures the air flowing into the engine intake. This is an essential part of your Mercedes because this information is critical in calculating how much fuel needs to be added to create a proper air-to-fuel ratio. If your vehicle can not measure this appropriately, your Mercedes may experience performance issues, including damage to your engine.
Typically, contamination is the reason why a mass airflow sensor fails. Dirt, air, and other road debris can get into the sensor, which causes it to begin to fail. As a driver, you might notice that your car is just not responding the way it once did. You could notice rough idling, stalling, and an overall sluggish driving experience.
Although this is an issue that is more prone to older cars. The more time has passed, the more opportunity debris has to gain entrance and find its way into the sensor. However, this has been an issue in some cars that have less than 25,000 miles. Usually, this happens with smaller and compact vehicles. The MAF is placed in a smaller engine bay which puts them more at risk for contaminants, such as debris and vapor from the combustion and oil.
