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

This oxygen sensor is intended as a replacement for a worn or faulty part on the Audi A3 (8L). As part of the restoration or maintenance of a classic vehicle, it ensures the measurement of oxygen content in exhaust gases, allowing the engine control unit to continuously adjust the air-fuel mixture. Replacement is generally necessary in case of excessive fuel consumption, increased emissions or illumination of the engine warning light. A preliminary diagnosis is recommended to confirm the fault before any intervention.
