PCV Valve Crankcase Vent Oil Separator Kit For Audi A3 A4 A5 VW CC 06H103495AH

PCV Valve Crankcase Vent Oil Separator Kit for Audi A3 A4 A5 VW CC

This PCV valve crankcase vent oil separator kit for Audi and Volkswagen engines replaces OEM 06H103495AH, regulating crankcase pressure and separating oil mist to protect the intake system.

Overview

The PCV valve crankcase vent oil separator kit for Audi A3, A4, A5, and VW CC is a direct-fit replacement that restores proper crankcase ventilation. By separating oil from blow-by gases, the PCV valve crankcase vent oil separator kit prevents carbon buildup on intake valves and reduces engine sludge. It suits shops and owners servicing 2.0T TFSI/TSI engines.

Built For Performance

• Calibrated diaphragm valve reacts precisely to manifold vacuum for stable PCV flow
• Multi-stage labyrinth oil separator traps oil mist and returns it to the sump
• Integrated check valve prevents boost pressure backflow in turbocharged setups
• High-temperature polymer housing resists warping under sustained engine heat
• Pre-installed gasket and seal ensure a leak-free installation out of the box
• Matches critical interface dimensions of 2.0T EA888 engines found in Audi and VW models

Fits These Machines

• for Audi A3
• for Audi A4
• for Audi A5
• for Volkswagen CC

On-The-Job Use

• Replacing a failed PCV valve causing rough idle, whistle, or oil leaks
• Preventive replacement during timing chain or water pump service on TSI engines
• Restoring crankcase ventilation to eliminate vacuum leaks and lean codes
• Reducing direct-injection intake valve carbon deposits by efficiently separating oil
• Commonly installed by repair shops performing TSI engine maintenance campaigns

Specs At A Glance

Good To Know

Q: How can I tell if my PCV valve has failed? A: Look for rough idle, a high-pitched whistle, oil residue around the valve cover, check engine light with lean or system-rich codes, or rising oil consumption.

Q: Does this kit include everything needed for installation? A: Yes, the assembly arrives with the integrated seal and gasket; no additional parts are needed for a standard swap on compatible engines.

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