Genuine OEM Audi Lambda Oxygen Sensor, part number 06E906265AA. This critical sensor is responsible for measuring the oxygen content in the exhaust gases, sending vital data to the engine control unit. This information allows the ECU to adjust the air-fuel mixture for optimal combustion, fuel efficiency, and reduced emissions. It is typically installed in the exhaust system, either before or after the catalytic converter. The sensor features a robust metal tip and an integrated electrical connector, with a total length of approximately 0.35 meters and a weight of 0.148 kg. Using a genuine OEM oxygen sensor ensures precise calibration and signal characteristics, which are essential for accurate engine management and compliance with emissions standards.
