Function and role of the vacuum reservoir tank

The vacuum reservoir tank in this model is responsible for storing the vacuum generated in the system so that it is available even during moments of variable engine load. A stable vacuum reserve is essential for the proper operation of vacuum-controlled components, which affects the engine's refinement and predictable response to driver inputs.

In high-power cars such as the RS6 C7 4.0 TFSI CRDB, maintaining appropriate vacuum parameters is important for performance repeatability, proper operation of auxiliary systems, and reducing the risk of diagnostic errors related to leaks or insufficient system capacity.

Intended for petrol engines

The presented vacuum reservoir tank has been designed to work with a petrol fuel type engine. This means the design is adapted to the operating characteristics of the TFSI unit, which experiences different pressure conditions than diesel engines. As a result, the component is properly matched to the specifics of the intake system and 4.0 TFSI petrol accessories.

Selecting a component consistent with the fuel type reduces the risk of compatibility issues and facilitates diagnostics in the event of potential leaks or vacuum drops in the system.

Benefits of using an original Audi component

The original Audi vacuum reservoir tank provides:

• structural consistency with the vacuum system in the RS6 C7 4.0 TFSI CRDB,
• appropriate capacity and operating characteristics matched to factory specifications,
• proper mounting and routing of vacuum lines,
• easier diagnostics based on manufacturer service data.

Using an original component from the Vacuum pumps group helps maintain the integrity of the entire system, which is important for both durability and subsequent service maintenance.

Used condition and installation aspects

The offered vacuum reservoir tank is a used part, which allows for an economical replacement while maintaining the original manufacturer's specifications. This type of part, sourced from dismantling, is a good solution when the existing tank has suffered mechanical damage, corrosion, or internal leaks.

Before installation, a standard check of the vacuum system is recommended – in particular the lines, connectors, and cooperating elements – to ensure full tightness and stable operating parameters after replacing the tank. A properly selected and installed tank reduces the risk of vacuum drops, which translates into more predictable operation of vacuum-controlled systems.

Technical support and part selection

In case of doubts regarding the selection of the component for a specific RS6 C7 4.0 TFSI CRDB configuration, it is worth consulting service documentation or manufacturer catalogs, especially when comparing part markings and interchangeable numbers. This helps avoid installing a component with different characteristics than those intended by the factory.

To better understand the relationships between engine power supply elements and accessories cooperating with the engine unit, a guide describing the diagnostics and selection of fuel components may be helpful – a detailed discussion can be found in the article Fuel system – injectors, pumps, and fuel tank: maintenance and regeneration.
