Description
This Bosch air mass sensor is a genuine Mercedes unit for S600, SL600 and CL600 V12 models. It carries primary OEM number A0000940848 and alternate Bosch number 0280217509. Designed for the intake system, it is the sensor that measures the air entering the engine so the management system can calculate accurate fueling and load.
Its job is to monitor intake air mass in real time and send that data to the engine control system. Correct readings help support smooth idle, stable acceleration, efficient combustion and proper throttle response, especially on high-output V12 engines where precise air measurement is essential.
Common signs of a faulty unit include rough idle, hesitation, flat acceleration, increased fuel consumption, hard starting, uneven power delivery or an engine warning light. A failing air mass sensor can also cause mixture-related running issues because the engine may receive incorrect airflow information.
This is a used original part, removed from a vehicle and tested. Match the exact OEM number before ordering. Professional installation is recommended, and intake system faults or stored fault codes should be checked during fitting to ensure the replacement sensor performs as intended.
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.
