Crankcase Vent Valve

The Genuine Audi 06E103547AF is an OE quality crankcase vent valve, manufactured in Germany. This vital component is part of your vehicle's emission control system, functioning as a PCV (Positive Crankcase Ventilation) valve. This valve manages pressure within the engine's crankcase by venting built-up gases back into the intake manifold, where they are then burned. This process helps to reduce harmful emissions, prevent oil contamination, and maintain optimal engine performance by controlling blow-by gases. Symptoms of a faulty vent valve can include rough idle or engine misfires, increased oil consumption due to potential leaks from stressed seals and gaskets, and the formation of sludge inside the engine if gases cannot escape properly. This crankcase vent valve is designed for specific Audi models including the A6 Quattro, A7 Quattro, A8 Quattro, and Q7. Specific fitment includes various trims and engine configurations for model years 2015 through 2019, predominantly featuring the 3.0L V6 engine, and also covers some 4.0L variants in later models. Please consult the detailed fitment list to ensure compatibility with your exact vehicle configuration. Associated part numbers include 06E 103 547 AF, 06E-103-547-AF, 06E-103-547-AF-VAG, 06E.103.547.AF, and 06E103547AF. This part also carries a Prop 65 Warning regarding cancer and reproductive harm.
