Description
This is a genuine Bosch air mass sensor for BMW E46 and E39 diesel models, supplied under OEM number 13627787076 with Bosch reference 0928400468. It is an original intake measurement component used to monitor the air entering the engine so the management system can calculate fuel delivery accurately.
By measuring incoming air mass in real time, this sensor helps the engine control system maintain the correct fuel mixture, smooth throttle response and efficient combustion. It plays an important role in diesel performance, idle stability, starting behavior and overall drivability.
Common signs of a faulty unit include hesitation under acceleration, uneven idle, reduced power, increased fuel consumption, smoky running or fault codes linked to air intake measurement. A failing sensor can also cause the engine to feel flat or inconsistent across the rev range.
This is a used original part, removed from a vehicle and tested before sale. Please match 13627787076 and 0928400468 exactly before ordering. Professional installation is recommended, and adaptation or system relearning may be required after fitting depending on vehicle setup.
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.
