Used Audi O2 / Oxygen Sensor (post Cat), OEM part number 4H0906265B — a genuine used post-catalyst oxygen sensor from a donor vehicle. This right-side sensor monitors exhaust gas oxygen content after the catalytic converter on 4.0L turbocharged V8 engines (3993cc) found in Audi A8 Quattro, RS7, S6, S7, and S8 models. When the sensor fails, you may notice a check engine light or reduced fuel economy.
