This OEM Oxygen O2 Sensor (Part Number: 077906265AD) is a factory-original component designed for seamless integration in a range of Audi vehicles. Compatible with 2000-2009 Audi models including the A4, A6, A8 Quattro, S4, and others equipped with engines from 1.8L L4 to 4.2L V8, this sensor is positioned downstream, post-catalytic converter. Its primary function is to monitor exhaust gases, ensuring optimal engine performance and emissions control. Replacing a worn or damaged sensor can resolve issues such as poor fuel efficiency and check engine light illumination. Alternative names include Rear Oxygen Sensor and O2 Sensor. This part directly replaces OEM numbers like 8E0254505RX and 1K0998262.
