Purpose and function in the fuel system

The described unit combines the function of a fuel pump and a float assembly with a level sensor, mounted on the left side of the tank, in a single housing. In cars with the 2.0 TFSI DJHA engine, it is responsible for stable fuel delivery to the rest of the fuel system and for transmitting information about the amount of fuel in the tank to the dashboard.

Thanks to its factory Audi design, this element works with the standard electrical system and fuel system, ensuring proper flow parameters and correct operation of the fuel gauge on the dashboard.

Construction and placement in the vehicle

The pump with sensor is intended for installation on the left side of the fuel tank, which is important for proper gasoline suction at different fill levels and under various driving conditions. The assembly works with the tank structure used in the Audi S3 8V, taking into account the specifics of the all-wheel drive and sports suspension.

As an OEM Audi component, it retains the factory mounting points, electrical connectors, and fuel connections, which facilitates installation and reduces the risk of leaks in the system.

Benefits of using an original Audi fuel pump

Using an original fuel pump with a level sensor in the Audi S3 8V offers a number of practical benefits:

• maintaining factory parameters for gasoline engine supply,
• correct cooperation with the vehicle's electronics and fuel gauge,
• compatibility with the tank geometry and fuel lines,
• reducing the risk of starting problems and engine stalling at low fuel levels.

For Audi S3 8V 2.0 TFSI DJHA owners, choosing an original, used OEM part is often a sensible compromise between cost and maintaining technical compliance with factory specifications.

Condition, verification, and selection by numbers

The item is from a disassembly and is offered as used, which in practice means it has already been used in a vehicle but is still suitable for further use after correct installation. For this type of part, matching by OEM number and interchangeable numbers is crucial – this helps to avoid problems with housing compatibility, connectors, and operating characteristics.

If you are considering a broader replacement of electronic components and sensors in your car, it is worth reading the guide on selecting used modules and sensors – you can find it in the article Used car electronics on board – why choose second-hand ECU modules and sensors?, which discusses, among other things, issues of designation compatibility, software, and practical aspects of installation.
