A-Premium PCV Valve Oil Separator Kit for Audi & VW 2.0L — Polyamide Housing + 2 Breather Hoses

The A-Premium PCV valve oil separator with breather hoses is a direct-fit replacement that removes crankcase vapors, helps reduce oil consumption, and restores proper ventilation on compatible Audi and Volkswagen 2.0L engines.

This oil separator kit is engineered for vehicles that use the 06H103495 family of parts and includes one polyamide oil separator housing plus two breather hoses. Designed as a pressure-controlled breather valve and mounted at the cylinder head, the unit replaces worn or leaking factory separators to address symptoms like oil smell, sludge buildup, or an illuminated engine light. It’s built to OE-style specifications so you get a close fit and reliable sealing.

Which cars will this A-Premium oil separator fit?

This kit fits many Audi and Volkswagen models equipped with 2.0L engines that reference OEM numbers 06H103495, 06H103495A/B/AC/E. Confirm your vehicle uses one of those part numbers before ordering to ensure compatibility.

• Audi: A3 (2008–2013, incl. Quattro), A4 (2009–2012), A5 (2010–2011), Q5 (2011–2012), TT Quattro (2009–2015).
• Volkswagen: Jetta (2008–2010, 2012–2013), Passat (2009–2010), Tiguan (2009–2015), Beetle (2012–2013), CC and Eos (2009–2015), GTI (2009–2014).
• Cross-check with engine codes CBFA, CCTA, CAEB and your car’s existing part number for a match.

How does replacing the PCV valve oil separator improve engine performance?

A functioning separator vents crankcase gases correctly and prevents oil from being drawn into the intake. Replacing a failed unit reduces oil contamination, lowers the chance of sludge, and helps the engine control systems operate within expected parameters.

• Restores proper crankcase ventilation and pressure control.
• Reduces oil consumption and oil deposits in intake components.
• Helps avoid related fault codes and poor idle or drivability issues.

What exactly comes in the A-Premium kit and what are the materials?

The kit supplies one oil separator housing made from durable polyamide 6.6 plus two matching breather hoses. The design follows pressure-controlled valve operation and is intended for installation at the cylinder head as a direct replacement piece.

• Contents: 1x oil separator, 2x breather hose — ready to swap with old components.
• Material: Polyamide 6.6 housing for chemical and heat resistance.
• Function: Pressure-controlled breather valve engineered for original-fit performance.

Can I install this myself, and what should I check after installation?

Many mechanically inclined owners can perform the swap with basic tools, but access varies by model and may require removing intake components. After installation, inspect for airtight connections, clear any stored fault codes, and monitor for normal idle and reduced oil consumption.

• Tip: Verify hose routing matches factory layout and clamps are secure.
• Aftercare: Clear engine codes and test drive to confirm symptom resolution.
• If problems persist, recheck fitment and part number compatibility (06H103495 variants).

Who this is for: This A-Premium oil separator kit is intended for Audi and Volkswagen owners and independent shops servicing 2.0L engines that show signs of PCV/oil separator failure — including increased oil use, intake contamination, or engine fault codes — and who need an OE-style, direct-replacement part referencing 06H103495, 06H103495A/B/AC/E. Choose this kit when you want a robust polyamide component, simple replacement contents, and broad fitment for model years listed.
