Oil Separator PCV Valve Vent Trim For Audi Q7 A8 Q5 S4 A6 A7 3.0T 06E103547AB

Oil Separator PCV Valve Vent Trim for Audi

The Oil Separator PCV Valve Vent Trim is a crankcase ventilation component that separates oil vapor from blow-by gases and routes them back through the intake, and it carries the OEM cross-reference 06E103547AB.

Overview

This oil separator PCV valve vent trim is a direct-fit replacement for the factory crankcase breather assembly found on several supercharged and turbocharged Audi engines. It captures oil mist from the crankcase, returns it to the sump, and keeps the intake charge cleaner. It is built for Audi owners and independent shops handling routine PCV service.

Specs At A Glance

Good To Know

Q: What are the signs this oil separator needs replacing? A: Common symptoms include increased oil consumption, blue exhaust smoke, a whistling noise at idle, and stored lean-running codes. A failed crankcase breather can also push oil into the intake tract and foul the throttle body.

Q: Can this be installed without removing the supercharger? A: On most 3.0T applications the breather sits under the supercharger, so access usually requires removing it first. A new gasket and careful torque sequencing are recommended during reinstallation.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
