Overview

This sensor plays a crucial role in controlling the fuel sent through the injectors based on air volume. A failing MAF sensor can lead to poor fuel mileage and reduced performance, potentially causing the vehicle to stutter or stall.

Show original supplier description

The BMW Mass Air Flow Sensor (MAF) is a critical component responsible for accurately measuring the volume of air entering the engine's intake. This hot film sensor, made in Germany, is integral to the precise control of fuel delivery through the injectors, ensuring optimal combustion and performance. Over time, MAF sensors can degrade, leading to a gradual loss of fuel efficiency and engine power. Symptoms of a failing MAF sensor can range from poor fuel mileage and a rough idle to the vehicle entering a limp mode with sputtering and stalling. Diagnosing a faulty MAF sensor can often be done by temporarily disconnecting it before starting the engine; if the idle improves significantly compared to its previous poor state, the MAF is likely the culprit. Ignoring a failing MAF sensor will result in increased fuel consumption as the engine receives too much fuel, directly impacting your vehicle's efficiency. This Genuine BMW part ensures stock quality for a direct replacement. This 3-pin mass air flow sensor is designed for various BMW E39, E46, and Z3 models, primarily from model years 1998 through 2003, with specific engines such as M52, M54, and M52TU. Fitment can vary based on production date and specific submodels, with notes indicating specific requirements like production dates from 09/1998 or up to 03/2003 for certain applications. It is essential to verify fitment using the vehicle selector or by consulting the detailed application list provided.
