Description
This is a genuine Bosch air mass sensor for BMW E65, E66 and E67 models including 735i and 745i. The primary OEM number is 7501554, with Bosch reference 0280218077 also marked for identification. It is an original intake measurement component used in the engine management system on these vehicles.
The sensor measures the amount of air entering the engine and sends that data to the control unit so fuel delivery can be adjusted accurately. A properly working air mass sensor supports smooth idle, stable throttle response, correct fuel mixture and efficient overall engine operation under changing load conditions.
Common signs of a faulty unit include rough idle, hesitation under acceleration, reduced power, increased fuel consumption, uneven running and engine warning lights related to air metering or mixture control. In some cases the vehicle may feel sluggish, surge intermittently or develop hard starting and inconsistent drivability.
This is a used original part, removed from a vehicle and tested before sale. Match 7501554 and 0280218077 exactly before ordering. Professional installation is recommended, and the intake system should be checked for leaks or contamination during fitting to help ensure correct operation.
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.
