A used OEM BMW O2 / Oxygen Sensor, part number 7539126. This sensor monitors exhaust gas oxygen content to help the engine control unit adjust the air-fuel mixture for proper combustion and emissions compliance. A failing sensor often triggers a check engine light, causes poor fuel economy, or leads to a rough idle.
