Vemo V20-72-5141 Mass Air Flow Sensor

Mass Air Flow Sensor for BMW Engine Management

The VEMO V20-72-5141 mass air flow sensor is a direct-fit emission control sensor for BMW engine management systems. It is built without a housing and uses a 5-pin connector layout, making it a focused replacement for vehicles that need accurate intake air measurement and stable drivability.

VEMO’s VEMO line is positioned for OE-style replacement parts, and this sensor follows that approach with application-specific fitment for select BMW 323i, 325i, 325xi, 330i, 330xi, 525i, 525xi, 530i, 530xi, and Z4 models.

Detailed Description

The VEMO V20-72-5141 measures incoming air so the engine control system can calculate fuel delivery and maintain proper air-fuel balance. This is especially important on BMW applications where precise airflow data affects idle quality, throttle response, and overall engine performance. The part number V20-72-5141 is listed for select 2004-2008 BMW 323i, 325i, 325xi, 330i, 330xi, 525i, 525xi, 530i, 530xi, and Z4 models with a 5-pin connector and without a measuring tube.

This part cross-references Continental 5WK97502Z and Spectra Premium MA329 for the same application.

What It Helps Address

• Rough or unstable idle caused by inaccurate airflow readings
• Hesitation during acceleration
• Reduced fuel economy from incorrect fuel metering
• Check engine light concerns related to airflow sensor performance
• Driveability issues after intake or air filter service

Installation Notes and Tips

Verify connector style, housing type, and engine application before installation. This sensor is specified without housing and with 5 poles, so matching the original connector and intake setup is important. Inspect the air filter and replace it if restricted, since a dirty filter can affect airflow readings and sensor life. Confirm fitment for your exact BMW model and year before ordering.

Quality Assurance

VEMO parts are positioned as OE-style replacement components for European vehicle applications. The V20-72-5141 is built to match the listed BMW fitments and sensor configuration requirements for consistent service replacement.
