SHUNSEN Auto Parts PCV Valve Oil Separator Kit for Audi & VW 2.0L L4 — Direct-Replace with 2 Breather Hoses

SHUNSEN's PCV Valve Engine Crankcase Vent Valve with breather hoses is a direct-replacement oil separator kit designed to restore correct crankcase ventilation and reduce oil blow-by for 2.0L inline-4 Audi and Volkswagen engines.

If your 2.0L Audi or VW with engine codes like CBFA, CCTA or CAEB is showing oil leaks, rough idling, or elevated crankcase pressure, a worn PCV valve and brittle breather hoses are often the cause. This aftermarket kit includes the crankcase vent oil separator plus two replacement breather lines sized and shaped to match OE routing for model years that originally used part numbers 06H103495, 06H103495B, 06H103495A, 06H103495E, and 06H103495AC. It's engineered for straightforward installation as a direct swap on compatible A3, A4, A5, Q5, TT and many VW models to return ventilation performance and help prevent oil contamination in the intake tract.

How do I know this kit fits my vehicle?

Fitment covers many Audi and Volkswagen models with 1.8L and 2.0L engines; compatibility is keyed to model year ranges and common engine codes. Confirm your engine code (CBFA, CCTA, CAEB, etc.) and compare part numbers listed with your factory part to ensure correct match.

• Fits Audi: A3 (2008–2013), A4 (2009–2012), A5 (2010–2011), Q5 (2011–2012), TT (2009–2015)
• Fits VW: Beetle (2012–2013), CC (2009–2015), EOS (2010–2015), GTI (2009–2014), Passat (2009–2010), Tiguan (2009–2015), Jetta (2008–2010, 2012–2013)
• Cross-references: 06H103495, 06H103495B, 06H103495A, 06H103495E, 06H103495AC

What problems does a failing PCV valve and breather hose cause?

A defective PCV valve or cracked breather hose allows crankcase pressure and oil vapors into the intake at the wrong rate, which can cause oil accumulation, poor idle quality, and increased emissions. Replacing the valve and hoses helps reduce oil seepage and restores intended ventilation behavior without requiring intake or valve cover replacement in many cases.

• Eliminates excessive oil in intake and intake tract deposits
• Reduces rough idling and intermittent misfires caused by vacuum leaks
• Prevents buildup of positive crankcase pressure that can force oil past seals
• Stops hose brittleness-related leaks common on older vehicles

How easy is installation and what’s included?

The kit is made for direct replacement using the original mounting points and hose routing; many owners can install it with basic tools. All fittings match OE-style connections so clamps and simple hand tools are typically sufficient for a secure, airtight fit.

• Package contents: 1 PCV valve / oil separator and 2 breather hoses
• Design: OE-style connectors and contours for direct swap
• Installation: hand tools and pliers for clamps; no specialized tools required
• Sealing: engineered for good airtightness to restore vacuum balance

What warranty and support come with the part?

SHUNSEN backs this kit with a 12-month warranty and customer support for fitment and installation questions. If you encounter any issues, the seller commits to responding within 24 hours via email for troubleshooting or warranty steps.
