This is a genuine VAG Nox-sensor, part number 04L907807EH. Designed and manufactured by VAG (Volkswagen Auto Group), this sensor plays a crucial role in your vehicle's exhaust system. Its primary function is to measure the amount of nitrogen oxides (NOx) present in the exhaust gases. This data is then sent to the engine control unit (ECU), which uses it to optimize the combustion process and manage the after-treatment system, such as the selective catalytic reduction (SCR) system. By accurately monitoring NOx levels, this sensor helps ensure your vehicle operates efficiently and complies with increasingly stringent emissions regulations. Replacing a faulty Nox-sensor is essential for maintaining optimal engine performance, fuel economy, and environmental compliance. A malfunctioning sensor can lead to increased emissions, reduced fuel efficiency, and potentially trigger warning lights on your dashboard. Trust in the quality and precision of genuine VAG parts to keep your vehicle running smoothly and cleanly.
