Oil Separator Engine Crankcase Vent Valve For 14-18 Audi A4 A5 TT VW Golf Passat

Oil Separator Engine Crankcase Vent Valve for Audi and VW

This engine crankcase vent valve oil separator effectively separates oil mist from blow-by gases to maintain proper crankcase ventilation and reduce oil consumption.

Overview

The oil separator engine crankcase vent valve is a direct-replacement PCV component designed to manage crankcase pressure and return oil vapor to the intake system. Engineered for 2014-2018 Audi A4, A5, TT, VW Golf, and Passat models, this oil separator engine crankcase vent valve helps prevent sludge buildup and oil leaks. Suitable for DIY and professional installation, it restores factory ventilation performance.

Built For Performance

• Precise internal diaphragm ensures consistent vacuum regulation
• High-temperature resistant polymer construction withstands engine bay heat
• Integrated oil separation baffles maximize mist capture
• Direct-fit design mates with factory connections and mounting points
• Prevents excess crankcase pressure that can lead to seal failures
• Tested for durability under variable boost and vacuum conditions

Fits These Machines

• for Audi A4 (2014-2018)
• for Audi A5 (2014-2018)
• for Audi TT (2014-2018)
• for VW Golf (2014-2018)
• for VW Passat (2014-2018)

On-The-Job Use

• Replacement during scheduled maintenance when the PCV system is inspected
• Repairing excessive oil consumption linked to faulty crankcase ventilation
• Addressing rough idle or stalling caused by vacuum leaks from a cracked separator
• Preventing sludge accumulation in intake valves on direct-injection engines
• Restoring proper crankcase ventilation on turbocharged 2.0T engines

Good To Know

Q: Does this oil separator require gasket replacement? A: Yes, it is recommended to replace the mounting gasket or O-ring during installation to ensure a leak-free seal.

Q: Will this part fit all 2.0T engines in the listed models? A: It matches the OEM crankcase vent valve used on the 2.0T TSI/TFSI engines from 2014-2018; confirm your engine code CPMA/CCTA/CBFA for precise fit.

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