Purpose and function in the powertrain

The presented secondary air pump is dedicated to Audi A6 C8, A7 4K, Q5 FY, and Q7 4M models with a 2.0 TFSI engine in a hybrid configuration. This component is responsible for supplying additional air to the exhaust system during the start-up and warm-up phase, supporting the mixture combustion process and stabilizing the engine's operation. Thanks to the use of a factory Audi solution, the secondary air system works in conjunction with the engine control electronics and emission control systems, which helps maintain proper operating parameters in urban driving modes, characterized by frequent engine starts and stops.

Benefits of using an original secondary air pump

Using an original secondary air pump in modern Audi models offers a number of practical benefits:

• maintaining proper cooperation with the factory engine control unit and hybrid system,
• stable operating parameters during cold starts,
• support for the exhaust emission reduction system,
• reducing the risk of errors appearing in the diagnostic system. Choosing an original component from this group allows you to maintain the consistency of the entire powertrain and reduces the need for additional modifications or adaptations.

Product characteristics and condition

The offered Audi secondary air pump comes from dismantling and is marked as used. Such components are frequently chosen for servicing modern TFSI units because they allow for maintaining factory specifications while reducing repair costs. The product is intended for installation in place of the factory pump, maintaining the original routing of hoses and connectors. In the case of hybrid systems, it is particularly important that the secondary air pump is compatible with the controller software and installation architecture – using an original Audi solution helps avoid compatibility issues.

Installation and operational tips

When replacing the secondary air pump, it is recommended to:

• check the tightness of air hoses and electrical connections,
• verify the condition of valves and cooperating elements in the secondary air system,
• clear any errors in the controller memory after installation. This approach allows you to restore the proper operation of the entire subsystem responsible for secondary air supply in a single service operation, which is important for both engine durability and emission measurement results.

Service expansion and additional information

If you are planning a comprehensive repair or upgrade of the engine area in your Audi and need other elements from the same group, such as additional pumps, valves, or secondary air hoses, check the available parts in the Audi Secondary air pumps category. When servicing TFSI and TDI units, it is worth paying attention to all engine accessories – the turbocharger, EGR valve, or auxiliary pumps. A detailed discussion of typical failure symptoms and the principles of selecting used components can be found in the article Failure of accessories in TSI and TDI engines: how to service a Volkswagen reasonably and not overpay at the workshop?. If you are interested in a broader context of using parts from dismantling in modern and older vehicles, practical tips on the safe selection of used components can be found in the entry No parts at the dealership?
