06A 906 265 E: Oxygen sensor for Audi A3 (8L)

The oxygen sensor equips the engine management system of the Audi A3 (8L) and plays an essential role in regulating the air-fuel mixture as well as in controlling exhaust emissions. In the context of restoration or routine maintenance of a classic vehicle, its replacement becomes necessary when the original sensor shows signs of failure, such as abnormal fuel consumption or excessive emissions. Prior electronic diagnosis makes it possible to confirm the origin of the malfunction before any intervention. This new component restores engine operation in accordance with the original specifications of the Audi A3 (8L).
