Purpose and Function in the Vacuum System

The vacuum hose in the Audi A6 C7 and A7 4G is responsible for the safe transmission of vacuum between system components, which is important for, among other things, the operation of the brake booster and other vacuum-controlled consumers. The appropriately selected shape and diameter of the hose allow for maintaining proper flow and limiting pressure drops in the system.

Using an original hose from this series allows for:

• maintaining the correct operating characteristics of the vacuum system,
• preserving the factory routing of the hose in the engine bay,
• minimizing the risk of leaks and improper power steering operation.

Benefits of Using an Original Audi Hose

The component from this group has been developed by the vehicle manufacturer with specific models in mind, ensuring precise fit to mountings and spigots and compatibility with factory brackets. In practice, this means no need for modifications, cutting, or adapting universal hoses.

The most important advantages of using an original hose include:

• maintaining the original geometry of the hose routing in the engine bay,
• appropriate stiffness and flexibility of the material under typical operating conditions,
• reducing the risk of chafing and kinks in critical areas.

Product Characteristics and Installation

The hose belongs to the Hoses, Pipes, and Tubes category, meaning it is an installation component responsible for transporting the working medium – in this case, vacuum. The hose's construction is adapted to the conditions in the engine bay, such as temperature changes, vibrations, and contact with other equipment components.

When replacing the vacuum hose, it is worth paying attention to:

• the condition of the spigots and connectors to which the hose is attached,
• proper positioning in the factory brackets,
• absence of twists and kinks after installation.

By maintaining the original hose geometry, installation is orderly, and the risk of installation errors is reduced.

Part Condition and Service Application

The offered vacuum hose is a used part, allowing for economical vehicle repair while maintaining the original manufacturer's specifications. This type of part is particularly suitable for situations where the existing hose shows signs of wear, cracking, material hardening, or leaks resulting in system performance degradation.

Hose replacement is recommended, among other things, for:

• perceptible decrease in brake assist effectiveness,
• noticeable leaks in the vacuum system,
• service work in the engine equipment area when the old hose is clearly worn.
