Volkswagen Golf V 1K Audi A4 B7 Crankcase Ventilation Hose Air Hose is a component from the Hoses, Tubes, and Pipes category, designed for the crankcase ventilation system in selected VAG group models. It is responsible for the controlled flow of gases from the crankcase breather, which is important for stable engine operation and proper system ventilation. This solution allows for maintaining the correct operating parameters of the powertrain while preserving the original hose routing geometry.

Application and Technical Function
The crankcase ventilation air hose used in the Volkswagen Golf V 1K and Audi A4 B7 models operates within the crankcase ventilation system, directing gases from the breather to further intake system components. The appropriately shaped cross-section and matched connector diameters ensure a tight seal with factory connectors, which reduces the risk of leaks, power loss, or unstable idle speeds.
This component is particularly important in engines where the crankcase ventilation system interacts with the intake system and mixture control. Proper flow of gases from the breather affects:
- maintaining correct crankcase pressure,
- limiting oil blow-by into the intake,
- stable engine control system operation.
Construction and Mounting Fit
The hose has been designed as a dedicated component for the specific engine bay architecture in Volkswagen and Audi vehicles, ensuring proper routing between mounting points. The shape and length of the hose are adapted to factory brackets and guides, which facilitates installation and minimizes material stress during engine operation.
The appropriately selected hose material is resistant to oil vapors and elevated temperatures in the engine bay. This allows the hose to maintain flexibility under typical operating conditions, and the risk of cracks or delamination is reduced with proper installation and use.
Condition, Origin, and Benefits of Use
The offered crankcase ventilation air hose is a used Volkswagen part, sourced from disassembly, which allows for maintaining factory fit to the engine system. Choosing an original part from disassembly is beneficial wherever compliance with factory specifications is important, as well as preserving the original hose and connector geometry.
Using this hose allows for:
- restoring proper crankcase gas circulation after damage to the old component,
- limiting oil leaks and contamination in the engine bay,
- maintaining stable powertrain operating parameters.
Installation and Operational Tips
When replacing the crankcase ventilation hose, it is recommended to check the condition of connectors, clamps, and adjacent intake system components. Particular attention should be paid to:
- precise seating of the hose on the connectors,
- absence of cracks or abrasions in bent areas,
- correct routing of the hose relative to heating and moving elements.
Careful installation reduces the risk of leaks and ensures longer, trouble-free operation of the crankcase ventilation system.
