The average cost of a BMW mass air flow sensor is between $30.99 and $269.99.
A mass airflow sensor for a BMW detects the amount of oxygen streaming into your engine to achieve the ideal air-to-fuel ratio. The mass airflow sensor improves engine efficiency, resulting in improved performance and fuel economy. It is situated between the air filter and the intake manifold of the engine. The intake air temperature (IAT) sensor is integrated into the mass air flow sensor in some vehicles. However, different types of air flow sensors require varied maintenance. Digital sensors output a frequency, whereas analog mass air flow sensors output a variable voltage. Both outputs are delivered to the engine control module to aid in the regulation of the air-fuel mixture in the automatic transmission system of the vehicle.
However, mass airflow sensor failure is a typical issue with BMWs. The check engine light on your dashboard is the first indication of a problem. The following are some other red flags to look out for:
- Rough running or idling
- Difficulty starting the engine
- Difficulty accelerating
- Excessive fuel consumption
- Engine dragging
BMW mass air flow sensors are built to last throughout the life of your vehicle. In truth, there is no set replacement interval. As a result, the sensor is typically not replaced until it fails. In general, your mass airflow sensor should last at least ten years, however this can vary based on a number of things. Contaminants such as carbon will eventually find their way into the mass airflow sensor, causing a buildup that makes it difficult for air to pass through. The lower air flow will impair the sensor's ability to accurately measure air levels in the engine, resulting in engine performance issues.
