The 04B103469K valve cover membrane is a replacement crankcase ventilation diaphragm for selected Audi, Volkswagen, Skoda and Seat 1.4 TDI applications. This 51 mm membrane is designed to restore the function of the existing valve cover ventilation unit without replacing the complete valve cover assembly.

Part Type
- Valve cover membrane
- Crankcase ventilation diaphragm
- PCV valve membrane
- 1.4 TDI valve cover diaphragm
What This Part Does
This membrane works inside the crankcase ventilation system integrated into the valve cover. When the original diaphragm becomes worn, torn or loses flexibility, the PCV system may no longer regulate pressure correctly. Replacing the membrane helps restore the function of the existing unit in a targeted and cost-effective way.
