11128579962 PCV Valve Cover Membrane for BMW B47B, B47D, B47F
This PCV valve cover membrane is designed for BMW B47B, B47D and B47F diesel engine applications using OEM reference 11128579962. It replaces the failed diaphragm in the valve cover crankcase ventilation system and helps restore correct pressure regulation.
This product is the membrane only. It is not a complete valve cover assembly or complete crankcase ventilation valve.
OEM / Reference Numbers
Primary OEM / valve cover reference number:
- 11128579962
- 11128579961
Alternative BMW OEM format:

- SKU: KL11128579962
Part Type
- PCV valve cover membrane
- valve cover diaphragm
- crankcase ventilation membrane
- engine breather diaphragm
- oil separator membrane
What This Part Does
The valve cover membrane regulates crankcase pressure and controls blow-by gas flow through the PCV system. When the diaphragm fails, the crankcase ventilation system can lose pressure balance and cause ventilation-related engine symptoms.
Replacing the failed membrane helps restore the function of the existing valve cover PCV system while avoiding replacement of the full valve cover assembly.
