Description
This is a genuine Bosch air mass sensor for BMW E90 and E60 diesel models, supplied under OEM number 13627788744 with Bosch reference 0928400504. It is an original intake measurement sensor used in the engine air path and designed for accurate airflow monitoring in these BMW diesel applications.
Its job is to measure the amount of air entering the engine so the control unit can calculate fuel delivery correctly. A healthy sensor supports smooth starting, stable idle, clean acceleration, efficient combustion, and proper turbo diesel performance across changing load conditions.
Common signs of a faulty unit include hesitation under throttle, uneven idle, reduced power, increased fuel consumption, smoke, limp mode, or engine management fault codes related to air quantity or mixture control. Contamination inside the sensor body can also affect reading accuracy and drivability.
This is a used original part, removed from a vehicle and tested before sale. Please match 13627788744 and 0928400504 exactly before ordering. Professional installation is recommended, and coding, programming or adaptation may be required where applicable after fitting.
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.
