This oxygen sensor is designed for Audi A6L (2005-2011; engines 2.4L, 3.0L, 3.2L, 4.2L) and also compatible with A8L, Q7 and VW Touareg MLB platforms. The core function is real-time monitoring of exhaust oxygen content and feedback to the ECU to adjust the air-fuel ratio for efficient combustion and reduced emissions. OEM numbers include 06E906265J, 06E906265D, and 06E906265AB, multiple part numbers for inventory convenience. Replacement difficulty is medium; use a dedicated socket to avoid thread damage; clean the interface and apply anti-seize compound before installation. For B2B buyers, the sensor uses an OEM-grade ceramic core with high-temperature durability, suitable for bulk purchase to cover multiple models.
