Description
This Bosch diesel air mass sensor is an original BMW fitment component for BMW E81, E87, E90 and E60 models. Primary OEM number 0928400529 identifies this mass air flow sensor used in the engine intake system. It is designed as the correct used replacement unit for the models named above.
Its job is to measure the amount of air entering the engine and send that data to the engine control system. Accurate airflow readings help the diesel engine manage fuel delivery, throttle response, emissions control and smooth running across idle, acceleration and cruising conditions.
Common signs of a faulty unit include poor acceleration, uneven idle, increased fuel consumption, reduced engine performance, smoke under load or warning lights linked to air intake and mixture control. On diesel BMW applications, incorrect air mass readings can also contribute to hesitation or inconsistent power delivery.
This is a used original part, removed from a vehicle and tested before sale. Please match the exact OEM number 0928400529 before ordering. Professional installation is recommended, and adaptation or fault-code clearing may be required after fitting depending on the vehicle system 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.
