Mass Air Flow Sensor Assembly For 04-06 VW Jetta Golf & 05-06 Beetle: Diesel

Mass Air Flow Sensor Assembly for VW Jetta Golf and Beetle

The Mass Air Flow Sensor Assembly measures the volume of air entering the engine so the fuel injection system can deliver the correct air-fuel mixture on 2004-2006 VW Jetta and Golf and 2005-2006 Beetle diesel models.

Overview

This mass air flow sensor assembly is the electronic meter that reads intake airflow and reports it to the engine control unit on your diesel Volkswagen. A healthy mass air flow sensor keeps fuel delivery accurate, supports smooth idle and throttle response, and helps avoid the check-engine codes and power loss that come with a failing meter. It is a direct-fit replacement part for drivers servicing 2004-2006 VW Jetta and Golf and 2005-2006 Beetle diesel vehicles.

• Built to read intake airflow and send a calibrated signal to the engine control unit
• Helps restore correct fuel delivery for smoother idle and throttle response
• Constructed for underhood temperatures and continuous diesel engine duty
• Direct-fit installation without adapter wiring or custom mounting

Fits These Machines

• for VW Jetta diesel 2004-2006
• for VW Golf diesel 2004-2006
• for VW Beetle diesel 2005-2006

On-The-Job Use

• Routine engine maintenance on TDI diesel Volkswagen models
• Resolving fault codes tied to intake air metering
• Restoring accurate fuel trim after a sensor failure

Specs At A Glance

Good To Know

Q: Will this sensor work with any engine, or only diesels? A: It is listed for the diesel engines in these models, so confirm your engine code before ordering. Gasoline engines use a different meter and are not covered by this listing.

Q: Do I need to reset anything after installing it? A: On many vehicles the engine control unit adapts to a new mass air flow sensor on its own, but clearing stored fault codes is good practice. Drive the vehicle after install and recheck for any remaining codes.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
