Description
This Bosch air mass sensor is a genuine Mercedes diesel intake component for Mercedes CDI models. The primary OEM number is A0041537328, with Bosch reference 0281002489. It is designed to measure the amount of air entering the engine so the management system can deliver the correct fuel quantity and maintain smooth diesel performance.
In normal operation, the sensor monitors incoming air mass in real time and sends that data to the engine control system. Accurate airflow readings are essential for clean combustion, stable idle, proper turbo diesel response and efficient fuel metering across changing load conditions.
Common signs of a faulty unit include hesitation under acceleration, uneven idle, reduced power, excessive smoke, poor fuel economy or an engine warning light. A failing air mass sensor can also cause rough running, incorrect fueling and inconsistent performance, especially on diesel engines that rely on precise airflow measurement.
This is a used original part, removed from a vehicle and tested before sale. Match the exact OEM number before ordering. Professional installation is recommended to ensure correct fit and operation, and adaptation or fault-code clearing may be required after replacement 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.
