Description
This is a genuine Bosch air mass sensor for BMW E60, E90, X3 and X5 models, supplied under primary OEM number 7805415-01 and alternate number 0281002936. It is an original intake management sensor used to measure the incoming air charge so the engine can respond correctly under different load conditions.
Its job is to monitor the volume and density of air entering the engine and send that data to the engine control system. Accurate airflow measurement helps support proper fuel delivery, smooth running, stable idle, clean combustion and consistent diesel performance across normal driving conditions.
Common signs of a faulty unit include hesitant acceleration, uneven idle, reduced power, excessive smoke, poor fuel economy or an engine warning light linked to air metering faults. A failing sensor can also cause incorrect fuel calculations, which may affect drivability and overall engine response.
This is a used original part, removed from a vehicle and tested before sale. Please match 7805415-01 and 0281002936 exactly before ordering. Professional installation is recommended, and calibration or adaptation may be required depending on vehicle configuration and workshop procedure.
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.
