Detailed Description

The Prenco 4M-1006 mass air flow sensor measures incoming air so the engine control system can calculate fuel delivery more accurately. This helps maintain proper drivability and emissions performance on select 2001-2006 Audi A4 and TT, 2001-2005 Audi A4 Quattro, and 2001-2006 Volkswagen Golf, 2001-2005 Volkswagen Jetta, 2001-2004 Volkswagen Beetle, and 2001-2002 Volkswagen Passat applications with housing. This part cross-references Beck/Arnley 158-0773 and Standard Ignition MAS0409 for the same application.

What It Helps Address

• Rough idle caused by inaccurate airflow readings
• Hesitation or poor throttle response
• Check engine light related to air metering faults
• Fuel trim issues from incorrect air/fuel calculation
• Reduced engine performance from a failing MAF sensor

Installation Notes and Tips

Verify connector shape, connector gender, and housing-style fitment before installation. This sensor uses one rectangular female connector and is listed for vehicles with housing, so confirm the original configuration matches before ordering. Inspect the intake tract, air filter housing, and wiring connector for contamination or damage during replacement. Use the vehicle’s service information for proper diagnostic and relearn procedures after installation.
