A-Premium PCV Valve Oil Separator for Audi & VW 2.0L — Housing + 2 Breather Hoses, OEM Fit

A-Premium PCV Valve Engine Crankcase Vent Valve Oil Separator with breather hoses is a direct-fit replacement that restores crankcase ventilation for select Audi and Volkswagen 2.0L engines.

This oil separator assembly (also called a PCV valve or breather) helps evacuate blow-by gases from the crankcase and separates oil from vapors before they re-enter the intake. Built from durable Polyamid 6.6, the kit includes one oil separator housing and two breather hoses, designed to match OEM fitment and mounting points for a straightforward swap. It fits a range of Audi and VW models that commonly use part numbers 06H103495, 06H103495A/B/E/AC.

Which vehicles will this A-Premium oil separator fit?

This unit is engineered for many Audi and Volkswagen models using the 2.0L engines listed by the manufacturer. Check your engine code or compare reference numbers before ordering to confirm compatibility.

• Audi: A3 (2008–2013), A3 Quattro (2009–2013), A4 (2009–2012), A4 Quattro (2009–2012), A5 (2010–2011), A5 Quattro (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 (2009–2015), Eos (2010–2015), GTI (2009–2014).
• OEM cross-reference: 06H103495 and its variations (A/B/E/AC).

How does replacing this breather help my engine’s performance?

A fresh PCV oil separator reduces oil carryover into the intake, prevents crankcase pressure build-up, and helps the engine run cleaner. It won’t fix unrelated mechanical faults, but it addresses symptoms tied to a failing separator such as oil consumption, smoke, and check-engine light triggers related to crankcase ventilation.

• Reduces oil vapors entering the intake tract, lowering carbon buildup.
• Maintains correct crankcase pressure for consistent engine operation.
• Helps resolve engine codes linked to PCV or boost system leaks.

What comes in the box and what materials are used?

The package contains one oil separator housing and two breather hoses—enough to complete a standard replacement on applicable engines. The housing is molded from Polyamid 6.6 for chemical and heat resistance matched to underhood conditions.

• Contents: 1x oil separator assembly, 2x breather hoses for direct swap.
• Material: Polyamid 6.6 polymer for durability and tight sealing.
• Operating mode: pressure-controlled breather valve, cylinder-head mounting.

Is installation straightforward and what should I check during fitment?

Installation is typically a bolt-on replacement using existing mounting points and clamps; basic mechanical skills are sufficient. Inspect surrounding vacuum lines and intake connections for wear, and replace any brittle hoses or clamps for a reliable seal.

• Fitment: direct replacement—no modification required on compatible models.
• Recommended: swap worn clamps and inspect adjacent vacuum lines.
• Tip: verify part reference (06H103495 variants) matches your original unit before installation.

Who is this for: Drivers and DIY mechanics who own compatible Audi or Volkswagen models looking to replace a failed oil separator or cure symptoms like increased oil consumption, smoke from the exhaust, or crankcase-ventilation related fault codes. It’s also suitable for shops performing routine maintenance on the 2.0L engines referenced—providing an OEM-style, polymer-bodied replacement with the hoses needed for a complete repair.
