Purpose and technical function

The presented vent hose is designed to work with the 1.4 petrol engine used in Volkswagen Touran 1T and Sharan 7N models. Its task is the controlled discharge of vapours and gases from specific areas of the power unit, which helps maintain stable operating pressures and improves engine refinement. Thanks to its factory profile and appropriately selected diameter, the hose ensures a tight connection with other system components. This reduces the risk of leaks, performance drops, or errors related to improper operation of the ventilation system.

Construction and fit for the petrol system

The hose belongs to a group of flexible components that must withstand temperature changes, contact with fuel vapours, and vibrations generated by the running engine. The construction of the hose is adapted to the specifics of petrol units, which helps maintain proper flexibility and resistance to typical operational loads. The appropriate profiling of the ends facilitates installation at original mounting points, without the need for modifications or the use of additional adapters. Such a solution allows for maintaining the factory geometry of the system, which is important both for tightness and for the correct routing of the hose in the engine compartment.

Benefits of using an original hose

Using an original vent hose instead of a worn or leaking component brings measurable operational benefits:

• maintaining proper gas circulation in the petrol engine system,
• reducing the risk of leaks and uncontrolled air intake,
• more stable operation of the power unit under various load conditions,
• maintaining the factory configuration of the lines, hoses, and pipes system. For users who care about the technical integrity of their vehicle, choosing an original hose from this group of components is a sensible solution, allowing for the reduction of diagnostic problems and speeding up potential future repairs.

Condition and service application

The item comes from the Volkswagen brand offer and is intended for re-installation in vehicles where it is necessary to replace a worn or damaged vent hose. It is suitable for both standard service maintenance and more extensive work related to the line system in the engine compartment. Selecting the correct hose from this group of components is particularly important in the case of petrol units, where tightness and proper ventilation affect combustion parameters and idle stability.
