The Genuine BMW Crankcase Vent Hose (part number 11-15-7-623-745) is an OEM replacement component designed for the positive crankcase ventilation (PCV) system. This hose connects the valve cover to the intake air pipe, allowing proper ventilation of crankcase gases back into the intake system for combustion.

This crankcase breather hose is a critical component of the engine's ventilation system, helping to prevent pressure buildup in the crankcase while routing blow-by gases back through the intake for efficient combustion. Over time, these hoses can deteriorate from heat and oil exposure, leading to vacuum leaks, rough idle, or check engine lights. Replacing with genuine BMW parts ensures proper fit and durability.
