06H103495 / 06K103495R Oil Separator Membrane for VAG 1.8 / 2.0 TSI TFSI
06H103495 is the main OEM reference number for this oil separator membrane, and the product page also lists 06K103495R as a related oil separator number for compatible VAG applications. This membrane is used in the crankcase ventilation / oil separator system and is intended as a repair solution for a failed diaphragm inside the separator assembly.
Over time, the original membrane can dry out, lose elasticity and tear. When this happens, unmetered air may enter the engine, which can cause rough idle, unstable running, poor starting behavior and whistling noise from the oil separator area.

What This Part Does
The oil separator membrane is an internal working element of the PCV / crankcase ventilation system. Its job is to help regulate pressure and control airflow inside the oil separator assembly. When the membrane becomes damaged, the system may begin drawing air that is not properly measured by the engine management system, which affects idle quality and overall running behavior.
Compatible Vehicles
According to the product page, this membrane is used in selected VAG vehicles including VW Passat, Passat CC, Audi A3, A4, A5, Q5, TT, Seat Exeo, Skoda Octavia, Superb, Yeti, VW Amarok, Beetle, CC, Eos, Golf and Jetta applications listed on the page.

FAQ
What does 06H103495 fit?
According to the product page, 06H103495 is used on a wide range of VAG vehicles including Audi A3, A4, A5, Q5, TT, VW Passat, Golf, Jetta, Beetle, Skoda Octavia, Superb, Yeti and Seat Exeo applications.
Is 06K103495R a related oil separator number for this membrane?
Yes. The product page explicitly lists 06K103495R together with 06H103495 as a compatible oil separator reference for this membrane.
What does this oil separator membrane do?
This membrane is an internal part of the oil separator / PCV system. It helps regulate crankcase pressure and airflow inside the separator assembly. When it tears, unmetered air can enter the engine and affect operation.
What symptoms can indicate a failed 06H103495 membrane?
Typical symptoms include whistling noise near the oil separator, poor starting, rough idle, unstable running and air entering the engine through a torn membrane.
Is this a complete oil separator assembly?
No. This product is the membrane only.
Does the ECU need time to adapt after replacement?
Yes. The page notes that after replacement the engine may not run steadily at first because the ECU had adapted to the torn membrane. After some running time and a restart, the system should adapt to the corrected airflow.
