OEM 06H103495AC Oil-water Separator Crankcase Ventilation Valve with High-Temperature Resistant Reinforced Plastic Housing and Sealing Pressure Tested Optimized Internal Separation Structure for VW Audi

This Oil-water Separator, OEM number 06H103495AC, is a vital engine system part designed for Volkswagen Golf, Audi A4L and Q5 with EA888 2.0T engines. It serves as the crankcase ventilation PCV assembly, separating oil mist from blow-by gas inside the crankcase. It returns collected lubricating oil back to the engine sump and routes filtered gas into the intake manifold for clean secondary combustion. A faulty separator often leads to excessive oil consumption, blue exhaust smoke, whistling noise, rough idle and carbon buildup on intake components.

It adopts high-temperature resistant reinforced plastic housing and an optimized internal separation structure, maintaining stable performance under repeated thermal cycling and pressure fluctuations. Produced strictly following OEM standards, it delivers accurate fitment and simple direct installation without extra modification. Every unit undergoes strict sealing and pressure testing before delivery. It is a reliable aftermarket replacement popular with auto repair shops and auto parts distributors.
