Description
This Bosch air mass sensor is a genuine used OEM intake sensor for VW Golf 5, Jetta, Passat and Audi A3 models. The primary OEM number is 03G906461C, with Bosch reference 0281002735. It is designed to measure incoming air with the accuracy the engine management system expects from an original factory component.
By monitoring the mass of air entering the engine, this sensor helps the ECU calculate the correct fuel delivery and maintain smooth performance, efficient combustion and stable emissions control. A properly working air mass sensor supports clean throttle response, balanced fuel mixture and dependable running across normal driving conditions.
Common signs of a faulty unit include hesitant acceleration, uneven idling, reduced power, increased fuel consumption, smoke under load or an engine warning light linked to airflow readings. In many vehicles, a failing sensor can also contribute to rough starting and inconsistent performance during gear changes or steady cruising.
This is a used original part, removed from a vehicle and tested before dispatch. Match the exact OEM number before ordering. Professional installation is recommended, and basic adaptation or fault-code clearing may be required after fitting depending on vehicle system condition and stored ECU data.
Returns accepted only for genuine faults — faulty on arrival, not as described, or wrong part supplied — requested within 14 days, with all 3 anti-tamper stickers intact. No returns for change of mind, incorrect installation, coding/programming, or buyer compatibility errors; checking compatibility (OEM number, firmware, vehicle) is the buyer’s responsibility.
