Purpose and Function in the Fuel System

The fuel rail with injectors is responsible for precise fuel distribution to the cylinders of the 3.0 TFSI engine, ensuring proper pressure and even dosing. This component works with the factory Audi engine control unit, allowing for the maintenance of correct combustion parameters, smooth operation, and the characteristic dynamics of the S4 and Q5 3.0 TFSI versions.

Its placement on the right side of the vehicle is crucial for compatibility – the rail is designed for the specific geometry of the engine, fuel line routing, and accessory arrangement in the engine bay.

Construction and Advantages of the Original Fuel Rail

The offered Audi fuel rail is an OE-class component, sourced from disassembly, meaning its original construction and operating parameters are preserved. The integrated gasoline injectors are matched to the characteristics of the 3.0 TFSI engine, ensuring the fuel system maintains:

• stable fuel pressure across the entire engine load range,
• even dosing to individual cylinders,
• correct throttle response and predictable acceleration dynamics,
• compatibility with the factory injection maps used in the Audi control unit.

The original design of the rail facilitates installation in place of a worn component, without the need for modifications to the fuel system or engine bay mounts.

Vehicle Placement and Installation Aspects

The fuel rail is intended for the right side of the engine, which is important when selecting parts for the 3.0 TFSI engine. Correct placement ensures:

• proper routing of fuel lines and injector electrical connectors,
• clearance fit with the intake manifold and other accessories,
• maintenance of the original fuel system geometry, promoting trouble-free operation.

Due to the specifics of high-pressure systems, installation by a workshop experienced with TFSI engines is recommended to ensure fuel system integrity and safe operation.

Condition and Application in Vehicle Service

This component is from disassembly and is intended for users who want to restore the functionality of the injection system in their Audi S4 B9 or Q5 FY 3.0 TFSI while maintaining the factory specification. This type of fuel rail with injectors is suitable for both typical repairs after a failure and for preventive replacement in case of fuel dosing issues, rough engine running, or performance loss.

By using an original Audi component, the risk of parameter mismatch, which often occurs with aftermarket parts of inconsistent quality, can be reduced.
