Oxygen Sensor (fits North American, A4 BEW) also known as lambda sensor
Original equipment part number: 06A906262BK
This is the O2 sensor, also known as lambda sensor, for A4 chassis cars (edc-16 BEW).This screws in place of the original sensor at the threaded bung in the exhaust pipe before the catalytic converter, and plugs into the factory wiring harness toward the rear of the car. If you are experiencing rough idle and misfires under load, or have a code in the engine controller that indicates a bad oxygen sensor, this could be the part you need.
One example of a code that might indicate replacing the lambda sensor:
16515 Oxygen (Lambda) sensor P0131
16515 - Oxygen (Lambda) Sensor B1 S1 P0131 - 000 - Signal too Low
This is not for early European edc-15 PD cars, only the EDC16 versions, as listed below:
