Purpose and Role in the Fuel System

The fuel pump in the Audi A3 8V 1.4 TFSI is responsible for transporting gasoline from the tank to the fuel rail at the correct operating pressure. A properly selected component ensures:

• stable engine supply across the full range of loads,
• correct operation of injectors and the control unit,
• trouble-free cold and warm starts.

As a part integrated with the tank module, the pump works with the fuel level sensor, which translates to accurate readings on the instrument cluster.

Compatibility and OEM Identification

The offered fuel pump is an Audi brand component, which simplifies matching it to a specific vehicle configuration. Identification by OEM part number and available replacement numbers allows verification of compatibility with a specific version of the Audi A3 8V 1.4 TFSI gasoline engine. This helps reduce the risk of purchasing an incompatible module and avoids installation issues.

If you have doubts about selection, it is advisable to compare the markings with the service documentation or use OEM number search to confirm full compatibility with the fuel system of your specific vehicle.

Technical Characteristics and Fuel Type

The pump is designed to operate in a system fueled by gasoline, which is crucial for safety and durability. Using the correct type of pump for the fuel type affects:

• material resistance to contact with gasoline and performance additives,
• correct operating pressure parameters,
• stable operation with varying fuel levels in the tank.

Choosing a pump dedicated to a 1.4 TFSI gasoline engine reduces the risk of overheating, pressure drops, and disruptions in the injection system's operation.

Condition, Application, and Benefits of Installation

The offered fuel pump is a used component, making it an attractive cost-effective alternative to new OEM parts. It is particularly suitable for situations where the priority is to quickly restore vehicle functionality while maintaining a reasonable service budget.

Replacing a faulty pump with a functional tank module allows you to:

• eliminate problems with engine starting and stalling,
• stabilize the engine's operation under load,
• reduce the risk of damage to other fuel system components.
