This emissions temperature sensor, part number 04L906088E, is a direct replacement for the original component on VAG vehicles. It plays a crucial role in monitoring the temperature of exhaust gases, providing vital data to the engine control unit (ECU). Accurate temperature readings are essential for the proper functioning of various emissions control systems, including the diesel particulate filter (DPF) regeneration process and exhaust gas recirculation (EGR) system. A faulty sensor can lead to increased emissions, reduced fuel efficiency, and potential engine warning lights. Manufactured to VAG's stringent quality standards, this sensor ensures reliable and precise measurements, contributing to the longevity and performance of your vehicle's emission system. Installation is straightforward for mechanics familiar with VAG components. By replacing a malfunctioning sensor with this genuine VAG part, you can restore your vehicle's emissions system to its intended operating parameters, helping to meet regulatory standards and maintain optimal engine health.
