Genuine OEM Audi Oil Separator, part number 06K103495BM. This essential component, often part of the PCV (Positive Crankcase Ventilation) system, separates oil vapor from crankcase gases before they are recirculated into the engine's intake. This process prevents oil consumption and maintains engine cleanliness. It is typically mounted on the engine. Made from durable, heat-resistant polymers, it weighs approximately 1 kg. Using a genuine OEM oil separator ensures proper function, maintains engine performance, and helps meet emissions standards by preventing oil contamination of the intake system.
