Global Parts 1813205 Mass Air Flow Sensor

Mass Air Flow Sensor for BMW Turbo Applications

Global Parts 1813205 is a mass air flow sensor for select BMW models with turbocharged intake systems. It measures incoming air volume and density so the engine control unit can calculate fuel delivery and ignition timing with the precision needed for stable performance and efficient combustion. This Global Parts 1813205 sensor is a direct-fit replacement for the sensor-only application listed below.

Key Features

• Measures intake air volume and density for accurate engine management
• Supports precise fuel injection and ignition timing control
• Sensor-only replacement for the listed BMW applications
• Cross-references Delphi AF10429 for the same application
• Cross-references OE-style part numbers 13627593624 and MA1125

Detailed Description

When a BMW mass air flow sensor begins to drift out of range, the engine control unit can receive incorrect airflow data and adjust fueling improperly. Global Parts 1813205 restores the airflow signal used by the ECU to manage combustion, throttle response, and efficiency. It is listed for a wide range of BMW 335i, 535i, X5, X6, 640i, 740i, X3, X1, 435i, 235i, and related models, including applications such as Fits 2013-2019 BMW 640i Gran Coupe, N/A and Fits 2007-2013 BMW 335i, N/A.

For buyers searching BMW 640i mass air flow sensor, BMW X5 MAF sensor, or BMW 335i replacement airflow sensor, part number 1813205 provides the fitment coverage shown in the catalog data. The sensor is also listed for a 90 Degree Connector configuration on Fits 2013-2014 BMW X3, N/A.

Common Issues This Part Addresses

• Incorrect air-fuel mixture from inaccurate airflow readings
• Rough idle or unstable engine operation caused by faulty sensor data
• Reduced throttle response from poor intake air measurement
• Check engine light related to mass air flow sensor performance
• Fuel economy loss caused by improper ECU fueling calculations

Installation Notes and Tips

Verify the connector style and application before installation, especially on BMW X3 models where both sensor-only and 90 Degree Connector listings appear. Inspect the intake tract, air filter housing, and wiring connector for contamination or damage before replacing the sensor. Clear diagnostic trouble codes after installation and confirm that live airflow data is reading correctly.

Quality Assurance

Global Parts 1813205 is built for the listed BMW applications and follows the airflow-measurement function required by the engine management system. It is a sensor-only replacement intended to restore accurate intake air measurement in the specified fitments.
