This is a genuine VAG Nox-sensor (Nitrogen Oxide sensor) with part code 05N907807H. It plays a crucial role in your vehicle's emissions control system by measuring the levels of nitrogen oxides in the exhaust gases. Accurate NOx readings are essential for the Engine Control Unit (ECU) to optimize the air-fuel mixture and manage the exhaust after-treatment system, such as the selective catalytic reduction (SCR) system. A properly functioning Nox-sensor helps in reducing harmful emissions and ensures your vehicle complies with environmental regulations. Replacing a faulty Nox-sensor with this genuine VAG part will restore your vehicle's emissions control efficiency, prevent potential engine performance issues, and avoid check engine lights related to NOx sensor faults. It is designed to meet the specific requirements of VAG vehicles for a perfect fit and reliable operation.
