Global Parts 1813216 Mass Air Flow Sensor

Mass Air Flow Sensor for Audi and Volkswagen

Global Parts 1813216 is a mass air flow sensor for select Audi and Volkswagen applications. It measures incoming air volume and density so the engine control unit can calculate fuel delivery and ignition timing with greater precision. This part number 1813216 is a direct-fit sensor-only replacement for the listed vehicles.

Key Features

• Measures intake air volume and density for accurate engine management
• Supports precise fuel injection and ignition timing control
• Sensor-only design for the listed applications
• Fits 1998-2000 Audi A6 Quattro, N/A, Sensor Only
• Fits 1998-2000 Volkswagen Passat, N/A, Sensor Only
• Fits 1998-1999 Audi A4, N/A, Sensor Only

Detailed Description

Global Parts 1813216 is built for vehicles that rely on accurate airflow measurement to maintain proper combustion. By reporting the amount and density of air entering the intake system, the sensor helps the engine control unit adjust air-fuel mixture and timing based on real operating conditions. This makes it a practical replacement for Audi A4, Audi A6, Audi A4 Quattro, Audi A6 Quattro, and Volkswagen Passat models in the listed years. This part cross-references Delphi AF10491 for the same application.

What It Helps Address

• Rough idle caused by incorrect airflow readings
• Hesitation or sluggish throttle response
• Fuel mixture faults related to inaccurate intake air measurement
• Reduced engine efficiency from poor air-fuel control
• Check engine light conditions tied to mass air flow sensor performance

Installation Notes and Tips

Verify the vehicle year, make, and model against the fitment list before installation. This sensor is listed as sensor only, so confirm the existing intake assembly and connector style match the application. Inspect the intake tract for leaks, contamination, or damaged wiring before replacing the sensor. For best results, clear diagnostic trouble codes after installation and confirm normal idle and throttle response.

Quality Assurance

Global Parts supplies this mass air flow sensor as an OE-style replacement for the listed Audi and Volkswagen applications. Part number 1813216 is referenced for fitment-specific replacement use on the vehicles shown above.
