This used OEM Audi oxygen sensor, part number 078906265P, is the post-cat downstream O2 sensor that monitors exhaust gas after the catalytic converter to verify converter efficiency and adjust fuel trim. Common failure triggers a check engine light for catalyst efficiency or oxygen sensor circuit faults, often accompanied by poor fuel economy or failed emissions testing. It fits Audi and Volkswagen models equipped with the 2.7L V6 turbo, 2.8L V6 naturally aspirated, 4.2L V8 naturally aspirated, or 4.2L V8 turbocharged engines.
