This is a genuine VAG Nox-sensor, part number 04L907807GK. It plays a crucial role in your vehicle's emission control system by accurately measuring the levels of nitrogen oxides (NOx) in the exhaust gases. Proper functioning of the Nox-sensor is essential for the engine control unit (ECU) to optimize the air-fuel mixture and manage the selective catalytic reduction (SCR) system. This leads to reduced harmful emissions and helps your vehicle meet stringent environmental regulations. Replacing a faulty Nox-sensor with this genuine VAG part will restore your vehicle's emission control efficiency, prevent potential engine performance issues, and avoid dashboard warning lights related to emissions. Ensure your VAG vehicle operates at peak performance and environmental compliance by installing this high-quality, direct-fit Nox-sensor.
