The Oxygen O2 Sensor - Post Cat Downstream, OEM part number 078906265AA, is a critical component located after the catalytic converter on various Audi models. Its primary role is to monitor the exhaust gases and relay this data to the engine control unit (ECU) to optimize fuel efficiency and emissions control. This sensor works closely with the catalytic converter and upstream O2 sensors to ensure the vehicle operates within safe emissions parameters. Common issues that necessitate replacement include poor fuel economy, engine misfires, or an illuminated check engine light due to a faulty sensor. This part is compatible with a range of Audi models, including the 2000-2009 Audi S4, A4, A6, and Allroad Quattro. Other part numbers associated with this sensor include 1K0998262 and various interchangeable parts. If you've noticed fluctuating performance or emissions-related warnings, it may be time to consider this essential OEM replacement.
