Used Audi O2 / Oxygen Sensor (pre Cat) – OEM part number 03C906262B, pulled from a donor vehicle. This genuine pre-cat oxygen sensor comes from the 6.0L W12 engine (naturally aspirated, DOHC) that powered the Audi A8 Quattro. It monitors exhaust oxygen content before the catalytic converter, feeding data to the ECU for precise fuel trim. A failing sensor often triggers a check engine light, reduces fuel economy, or causes idle roughness. Direct OEM replacement for the specified application.
