Description
This is a genuine Bosch air mass sensor for BMW X1 E84, E90 and E87 models with the N47 diesel engine. The primary OEM number is 8506409, with Bosch reference 0281006093. It is an original intake metering component used to measure the volume of air entering the engine so the control system can calculate fuel delivery correctly.
Its job is to provide accurate airflow data for efficient combustion, stable idle, smooth acceleration and proper emissions control. A healthy sensor helps the engine management system balance fuel quantity against the real amount of incoming air, which is especially important on modern diesel engines where drivability and efficiency depend on precise readings.
Common signs of a faulty unit include hesitant acceleration, uneven idle, reduced power, increased fuel consumption, smoky running, limp mode or an engine warning light linked to airflow plausibility or signal faults. Airflow issues can also affect throttle response and overall engine smoothness.
This is a used original part, removed from a vehicle and tested before sale. Please match the exact OEM number before ordering. Professional installation is recommended, and adaptation or calibration 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.
