Genuine OEM Volkswagen EGR Valve, part number 038131501BH. This valve plays a critical role in the emissions control system by recirculating a portion of the engine's exhaust gases back into the combustion chambers. This process helps to lower combustion temperatures, thereby reducing the formation of nitrogen oxides (NOx) emissions. The valve is typically located near the exhaust manifold or intake manifold. Weighing 0.758 kg, this assembly combines metal and plastic components for durability. Opting for a genuine OEM EGR valve ensures precise calibration, proper sealing, and reliable operation, which are crucial for maintaining emissions compliance and engine efficiency.
