Genuine OEM Audi Exhaust Gas Recirculation Valve, part number 04L131501S. This valve plays a critical role in emissions control by recirculating a portion of the exhaust gases back into the engine's combustion chambers. This process helps to lower combustion temperatures, thereby reducing the formation of harmful nitrogen oxides (NOx). Weighing approximately 1.189 kg, this valve assembly includes integrated piping and an electrical connector. A genuine OEM EGR valve ensures precise calibration, proper sealing, and reliable electronic operation for effective emissions reduction and optimal engine performance.
