This is a genuine VAG NOx (Nitrogen Oxide) sensor, part number 04L907807DM. It plays a crucial role in modern vehicle emissions control systems by accurately measuring the levels of nitrogen oxides in the exhaust gases. By providing real-time data to the engine control unit (ECU), this sensor helps to optimize the combustion process and manage the after-treatment system, such as the selective catalytic reduction (SCR) system. This ensures that your vehicle meets stringent emissions standards and operates efficiently. Replacing a faulty NOx sensor with this genuine VAG part will restore proper emissions control, prevent potential engine performance issues, and help avoid check engine lights related to emissions. It is designed and manufactured to the exact specifications of your VAG vehicle for a perfect fit and reliable operation.
