Description
This is a genuine Hitachi air mass sensor for Audi A6 4F C6 2.7 TDI and 3.0 TDI models, supplied under OEM number 059906461K. It is the intake metering sensor that monitors the amount of air entering the engine so the management system can calculate accurate fueling and maintain proper diesel performance.
In normal operation, the sensor measures incoming air mass and sends that data to the engine control system. Correct airflow readings are essential for stable idle, smooth acceleration, efficient combustion, balanced turbo response and controlled emissions across the intake and fuel delivery system.
Common signs of a faulty unit include poor throttle response, uneven running, hesitation under load, increased fuel consumption, loss of power, smoky exhaust or an engine warning light. On diesel vehicles, incorrect airflow data can also contribute to rough driving behavior and reduced efficiency.
This is a used original part, removed from a vehicle and tested before sale. Please match the exact OEM number 059906461K before ordering. Professional installation is recommended to ensure correct diagnosis and fitment, and related fault codes or intake issues should be checked during installation.
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.
