This genuine VAG Emissions Temperature Sensor, part code 04L906088FD, is a critical component for your vehicle's emission control system. It accurately measures the temperature of exhaust gases, providing vital data to the engine control unit (ECU). By monitoring exhaust gas temperature, the ECU can make real-time adjustments to fuel injection, ignition timing, and exhaust gas recirculation (EGR) to maintain optimal combustion efficiency and minimize harmful emissions. A malfunctioning temperature sensor can lead to increased fuel consumption, poor engine performance, and illuminated check engine lights. Crafted to meet VAG's stringent quality standards, this sensor guarantees durability and consistent performance. Replacing a faulty sensor with this genuine part ensures your vehicle's emission system operates as designed, helping you comply with environmental regulations and maintain a healthy engine. Installation of this sensor should be performed by a qualified technician to ensure proper fitment and function. Refer to your vehicle's service manual for specific installation procedures and torque specifications.
