Description
This is a genuine Bosch air mass sensor for BMW E46 models, supplied under OEM number 1433565 with alternate reference 0280217124. It is an original intake management sensor used on selected E46 applications and built to the standards expected from an OEM Bosch component.
Its job is to measure the amount of air entering the engine so the control unit can adjust fuel delivery accurately. A properly working sensor helps maintain smooth running, stable idle, clean throttle response and efficient combustion across everyday driving conditions.
Common signs of a faulty unit include rough idle, hesitation under acceleration, flat performance, increased fuel consumption or an engine warning light. In some cases, hard starting, uneven running or poor low-speed response can also point to an air mass sensor that is no longer reading airflow correctly.
This is a used original part, removed from a vehicle and tested before sale. Please match 1433565 and 0280217124 exactly before ordering. Professional installation is recommended, and basic adaptation or fault-code clearing may be required after fitting where appropriate.
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.
