Purpose and function in the fuel system

The described fuel pump and level sensor control module is a component dedicated to Audi vehicles with petrol engines, particularly for the high-performance RS6 C7 and RS7 4G generation models. Its task is to control the operation of the in-tank fuel pump and transmit fuel level information to the onboard system, which is crucial for the proper operation of the powertrain and the accuracy of the onboard computer readings.

A properly functioning module of this type contributes to:

• stable fuel pressure in the petrol engine supply system,
• correct engine starting under various operating conditions,
• accurate fuel level readings on the dashboard,
• consistent operation with the vehicle's control electronics.

Construction, integration, and compatibility

The module belongs to the Fuel pumps and level sensors group, meaning it is designed to work with both the mechanical part of the fuel system and the vehicle's electronics. It covers the power control of the in-tank fuel pump and handles the signal from the fuel level sensor, making it the central point for managing this area.

As an original Audi component, the module is optimized for:

• integration with the factory wiring harness,
• compatibility with engine control unit software and the instrument cluster,
• maintaining factory operating parameters of the fuel system in the petrol engine.

The product has an assigned OEM part number and interchangeable numbers, which facilitates verification of compatibility with a specific vehicle configuration and minimizes the risk of selecting the wrong component.

Condition, application, and benefits of installation

The offered module is a used component, which allows for an economical repair of the fuel system while maintaining the manufacturer's original specifications. Replacing a faulty fuel pump and level sensor controller with a functional OEM component is particularly important in high-power vehicles such as the RS6 C7 and RS7, where stable petrol engine supply has a direct impact on performance and driving safety.

The main advantages of using this module include:

• factory fit for Audi installations – no need for wiring or mounting modifications,
• preservation of original fuel system operating parameters,
• consistency with the vehicle's diagnostic systems,
• ability to restore correct fuel level readings after a failure of the previous component.

Selection by part numbers and technical support

Due to the complexity of automotive electronics and differences between equipment versions, the selection of the correct fuel pump and level sensor control module should be based on the OEM part number, interchangeable numbers, and vehicle data. Proper identification of the component helps avoid hardware and software compatibility issues.
