This is a genuine VAG Nox sensor, part number 05N907807E. The Nox sensor plays a critical role in modern vehicle emissions control systems by measuring the levels of nitrogen oxides (NOx) in the exhaust gases. Accurate NOx readings are essential for the proper functioning of the engine's management system and the exhaust after-treatment system, such as the Selective Catalytic Reduction (SCR) system. By providing real-time data, this sensor helps the vehicle's computer to optimize fuel combustion and manage the injection of reductants (like AdBlue) to minimize harmful NOx emissions. Replacing a faulty Nox sensor with this genuine VAG part will help restore your vehicle's emissions control performance, prevent potential 'check engine' lights, and ensure compliance with environmental regulations. Trust in VAG quality for reliable and accurate sensor performance.
