Crankcase Breather / Oil Separator OEM VAG 06K103495BL

Crankcase Breather / Oil Separator VAG 1.8 TSI and 2.0 TSI - OEM (06K103495BL)

Genuine VAG crankcase breather, also known as oil separator or PCV module, for the 1.8 TSI/TFSI and 2.0 TSI/TFSI engines of the VAG group.

The crankcase breather separates the oil mist from the blow-by gases and returns the cleaned gases to the intake via a pressure control valve. The separated oil drains back into the crankcase. This keeps the crankcase pressure within the correct range and limits oil consumption through the intake.

If the diaphragm of the pressure control valve tears or the housing leaks, unmetered air enters and the crankcase pressure is no longer correct. The engine then runs rough. Persistent over- or under-pressure in the crankcase can also cause oil seals and gaskets to leak.

This is a genuine OEM VAG part.

Always check the OE number of the part fitted to the vehicle before ordering, or have the application checked by registration number. Different versions were used within the same engine family.

Possible symptoms

A faulty crankcase breather can cause symptoms such as:

• Rough or irregular idle
• Loss of power and poor throttle response
• Unmetered air through a leaking housing or a torn diaphragm
• Whistling or sucking noise from the area of the valve cover
• Increased oil consumption because oil mist is drawn into the intake
• Leaking oil seals and gaskets caused by incorrect crankcase pressure

The information supplied with this item does not include specific fault codes.

Important fitting information

PLEASE NOTE: always compare the OE number and the connections with the part fitted to the vehicle before installing. Several versions of the crankcase breather were used on the 1.8 and 2.0 TSI/TFSI engines, and they are not interchangeable.

Fit the part according to the manufacturer's instructions and the specified torque values. Clean the sealing surface before fitting and check the crankcase pressure and the system for leaks after fitting.
