Purpose and role in the fuel supply system

The presented high-pressure pump operates in the direct gasoline injection system of the 2.0 TFSI CVKB engine, used in Audi A4 B9 and Audi A5 F5 models. Its task is to increase fuel pressure from the low-pressure level (in-tank pump) to the values required by direct injectors, which translates into correct mixture formation and stable engine operation. Thanks to its factory design, the pump works with the original engine control system, maintaining the parameters specified by the vehicle manufacturer. This is particularly important in modern TFSI units, where the precision of fuel dosing affects performance, fuel consumption, and exhaust emissions.

Construction and technical features

The pump belongs to the High-pressure fuel pumps group, meaning it is mounted directly on the engine and driven mechanically. This type of solution allows for high operating pressure while maintaining compact dimensions and adequate body rigidity. Key design features include:

• designed for use with the 2.0 TFSI CVKB gasoline engine in Audi A4 B9 and Audi A5 F5 platforms,
• OEM construction, ensuring proper mounting points and compatibility with factory engine equipment,
• adapted for operation in a direct fuel injection system with electronic control. This type of pump is a precision component, and its correct operation has a direct impact on engine refinement, acceleration dynamics, and idle stability.

Benefits of using an original Audi pump

Using an original high-pressure pump in an Audi A4 B9 or A5 F5 allows you to maintain the consistency of the entire fuel supply system with the manufacturer's factory standards. You receive:

• reliable mounting fit – compatibility with factory mounting points and fuel lines,
• proper cooperation with engine electronics – no need for ECU software modifications,
• maintenance of the 2.0 TFSI unit's operating characteristics in accordance with the Audi design. Choosing a used OEM component is often a reasonable compromise between repair costs and maintaining original build quality and operating parameters.

Condition, verification, and part selection

The pump is offered as a used component, sourced from dismantling, which allows for an economical repair of the fuel supply system while maintaining the factory design. Before installation, it is recommended to perform a standard inspection of the vehicle's fuel system (filter, lines, tightness) to avoid secondary damage resulting from contamination or incorrect pre-pressure. To select the correct component for your car, it is worth comparing the pump markings with the vehicle data and the manufacturer's specification. The product has an OEM part number and interchangeable numbers, which facilitates matching to a specific engine configuration and model year.
