Detailed Product Overview
The Standard Ignition MAS0236 mass air flow sensor measures incoming air so the engine control system can calculate fuel delivery and maintain proper drivability. This part number is used across several BMW platforms, including the X5, 330i, 330xi, 330Ci, 530i, and Z3, making it a practical replacement when the original sensor is worn, contaminated, or no longer reading correctly. This part cross-references Delphi AF10222 and Beck/Arnley 158-1537 for the same application.
Common Problems This Sensor Can Address
- Rough idle caused by inaccurate airflow readings
- Hesitation or stumble during acceleration
- Check engine light related to air metering faults
- Poor fuel control from a failing MAF sensor
- Driveability issues after intake contamination or sensor wear
Installation Notes and Tips
Verify connector shape, terminal style, and mounting points before installation. Clean the air intake tract and inspect the air filter housing, ducting, and seals so the new sensor is not exposed to debris or unmetered air. Confirm the vehicle build date where noted, since some BMW X5 applications are listed with cutoff dates such as to 9/06, to 9/05, and to 9/04, and the 2003 BMW 330i application is listed to 9/02.
Quality Assurance
Standard Ignition supplies aftermarket emission control sensors for direct replacement use. MAS0236 is built as a complete assembly to support OE-style fitment and consistent sensor replacement on the listed BMW applications.
