Oil Separator 06J103464 06J-103-464 for Audi A3 A4 A5 Q5 VW Golf Tiguan Passat — OEM PCV Valve
Product Overview
The Crankcase Breather Oil Separator with OEM number 06J-103-464 (also listed as 06J103464, 06J 103 464) is a verified OEM-grade replacement for a wide range of Audi and Volkswagen vehicles equipped with EA888 Gen2 engines. This component—commonly referred to as the PCV (Positive Crankcase Ventilation) valve or oil separator / oil trap—is a critical part of the engine's crankcase ventilation system.
Real Shop Test Data: Precision-engineered for the EA888 Gen2 engine family—verified against VAG Group OEM specifiions
Proven Durability: Constructed with industrial-grade, wear-resistant materials (PA66-GF35) to withstand high-stress engine environments—rated for 160,000+ km (100,000+ miles) under normal operation
Installation Success Rate: 99% direct plug-and-play fitment—confirmed across thousands of repair orders for VAG 1.8/2.0 TFSI/TSI vehicles
If your oil separator is failing, you may experience one or more of the following symptoms:
Check Engine Light (CEL): Illumination with diagnostic trouble codes related to the PCV system or lean/rich fuel mixture
Excessive Oil Consumption: Noticeable drop in oil level between service intervals—oil is being drawn into the intake manifold and burned
Rough Idle or Engine Misfire: Engine runs unevenly at idle or stumbles during acceleration due to unmetered air entering the intake
Whistling or Hissing Noise: A high-pitched noise from the engine bay, often indiing a torn diaphragm inside the separator
Blue Exhaust Smoke: Oil burning in the combustion chamber, producing a bluish tint from the exhaust
External Oil Leak: Oil seeping from the separator or surrounding gaskets
Warning: A failing oil separator can lead to increased oil consumption, fouled spark plugs, damaged alytic converters, and potential engine damage. Prompt replacement is essential.
