For BMW Air Quality Sensors 64119872065 / 64116833647

1. Made of high-temperature resistant and corrosion-resistant engineering plastics, it can adapt to the complex environment inside the vehicle.
2. Replacement part number (OEM): 64119872065 / 64116833647
3. Working principle: This sensor integrates a heating gas detector inside, used to automatically sense external pollutants.
4. When the engine starts and the AUC function is enabled, the sensor automatically switches between the fresh air mode and the air circulation mode by sensing the external air quality (such as carbon monoxide, hydrocarbons, and nitrogen oxides) to maintain the air quality inside the vehicle.
5. The front end has a perforated probe cover and a standard automotive-grade electrical plug at the rear, making it easy to directly insert into the original vehicle wiring harness.
