Audi / Volkswagen Mass Air Flow Sensor / MAF 03G906461C

The Mass Air Flow Sensor (MAF), OEM part number 03G906461C, is a critical component located in the air intake system of your vehicle. It measures the amount of air entering the engine, enabling the engine control unit (ECU) to optimize the fuel-air mixture for combustion. This sensor is particularly important for maintaining efficiency in diesel engines and is commonly found in models like the 2010-2015 Audi A3 and various Volkswagen models, including the Golf, Jetta, and Beetle, equipped with a 2.0L L4 Diesel engine. Common indicators of a faulty MAF sensor include rough idling, a decrease in fuel efficiency, or illuminated dashboard warning lights. If you notice these symptoms, replacing the MAF with a genuine OEM part will restore performance, ensuring that your engine operates as intended. This part may also be referred to as an air mass sensor or air meter, and is compatible with additional part numbers such as 357129625A and 1K0805965J9B9.
