Product Details

VEMO V20-72-5178-1 is a replacement mass air flow sensor for BMW 328d, BMW 328d xDrive, and BMW X3 diesel models that use OE number 13628506408. The sensor measures incoming air so the engine control system can calculate fuel delivery and airflow-related adjustments with the correct signal. VEMO’s VEMO product line focuses on OE-style replacement components for European vehicle systems, and this sensor follows that approach with the specified connector shape, 5-pole layout, and housing-free design. Cross-reference part numbers include 8 506 408 and 13 62 8 506 408 for the same application.

What It Helps Address

• Incorrect airflow readings from a failing MAF sensor
• Check engine light related to air metering faults
• Rough idle caused by inaccurate intake air measurement
• Reduced throttle response from poor airflow signal data
• Fuel trim issues tied to contaminated or worn sensor elements

Installation Notes and Tips

Verify the OE number 13628506408, connector shape, and 5-pin configuration before installation. This part is listed without a measuring tube and without housing, so confirm the intake assembly matches the vehicle application. For BMW 328d, BMW 328d xDrive, and BMW X3 diesel fitment, compare the existing sensor dimensions and connector style to the original unit before replacement.
