11127552281 / 11127548196 PCV Membrane for BMW N52, N52N, N52K, N52T, N51, N53
This PCV membrane is designed for BMW N52, N52N, N52K, N52T, N51 and N53 engines using OEM references 11127552281 and 11127548196. It replaces the failed diaphragm inside the valve cover PCV unit and helps restore correct crankcase ventilation.
This product is the standalone membrane only. It is intended for vehicles where the PCV cover design allows membrane replacement and is not a complete valve cover assembly.

- 11127552281
- 11127548196

Part Type
- PCV membrane
- valve cover diaphragm
- crankcase ventilation membrane
- engine breather diaphragm
- standalone PCV diaphragm
What This Part Does
The PCV membrane regulates crankcase pressure and controls oil vapor and blow-by gas flow through the valve cover ventilation system. When the membrane fails, oil mist can enter the intake, oil consumption may increase, and crankcase ventilation faults can appear.
Replacing the failed diaphragm helps restore pressure regulation and supports proper PCV function while keeping the existing valve cover in service.
