Application and Technical Characteristics

The injector presented belongs to the category of injector nozzles and is intended for TFSI gasoline engine fuel systems in Audi S1 8X, Audi A3 8V, and Volkswagen Polo 6R models. The design developed by the Volkswagen Group manufacturer ensures proper fuel atomization, which translates to even combustion, stable RPMs, and predictable throttle response.

The injector works with gasoline fuel systems, meaning appropriately selected flow parameters, operating pressure, and needle opening characteristics. This allows for maintaining the correct mixture composition across the entire load range – from idle to dynamic acceleration.

Benefits of Using an Original Injector Nozzle

Using an original Volkswagen Group injector in a 1.8 TFSI engine allows for maintaining factory engine control unit settings without the need for fuel map modifications. This results in:

• stable engine operation – reduced vibrations, misfires, and uneven idling,
• consistent fuel delivery – predictable vehicle behavior during acceleration and at constant speed,
• better combustion control – support for proper lambda sensor and catalytic converter operation,
• preservation of factory performance – proper dynamics and flexibility of the 1.8 TFSI engine.

Component Condition and Selection Based on Technical Data

The injector is offered as a used part, allowing for economical repair of the fuel system while maintaining an OEM-class component. Before installation, a standard diagnostic procedure in the vehicle is recommended (checking injector operating parameters, fuel system leak test, and electrical system condition).

The selection of this injector nozzle should be based on data such as the engine code, vehicle production year, and manufacturer identifiers (OEM and interchangeable numbers). This will ensure that the component will work correctly with the fuel rail, engine control unit, and other fuel system components.

Operation, Diagnostics, and Technical Knowledge

A functional gasoline injector is crucial for the durability of the TFSI engine – it affects combustion temperature, piston, valve, and turbocharger load. In case of fuel system problems, it is important to know the typical symptoms of injector wear or contamination. Although the presented component is for a gasoline engine, many diagnostic procedures are similar to those used in diesel engines – more information can be found in the article diesel injector faults – symptoms, consequences, and diagnostics, which helps understand the importance of proper fuel atomization and the consequences of neglect.
