Purpose and Technical Characteristics

The presented diesel fuel injector belongs to the Injector Nozzles category and is factory-designed for the 3.0 TDI CDUC specification in Audi A6 C7 and Audi A7 4G models with quattro drive. The construction, adapted for diesel operation, guarantees proper fuel spray formation, adequate injection pressure, and dose repeatability across the entire load range.

Original origin from the Audi group means adherence to parameters specified by the vehicle manufacturer, which is crucial for correct engine control unit operation, injection map compatibility, and stable combustion in a diesel engine.

Benefits of Using an Original Injector Nozzle

Using a factory injector nozzle in a 3.0 TDI engine offers a range of tangible operational benefits:

• Stable Engine Operation – proper diesel atomization reduces vibrations, rough idling, and power loss.
• Improved Throttle Response – precise fuel metering supports dynamic acceleration, especially in high-load driving modes.
• Reduced Smoke Emission – the correct fuel spray pattern promotes more complete combustion, reducing visible exhaust smoke.
• Protection of Associated Components – correct fuel injection reduces the load on the turbocharger, diesel particulate filter, and exhaust gas recirculation system.

By maintaining factory injection parameters, the fuel system remains consistent with the control unit's software, facilitating diagnostics and subsequent service.

Condition, Selection, and Installation

The offered component is a used injector nozzle, allowing for economical repair of the injection system while maintaining original Audi specifications. This type of component is particularly useful when replacing a single injector in a 3.0 TDI engine, where other elements are functioning correctly.

When selecting, it is recommended to:

• verify compatibility with the engine code (3.0 TDI CDUC) and the A6 C7 / A7 4G body generation,
• check compatibility with the quattro drivetrain to maintain manufacturer-specified operating parameters under load,
• install in a specialized service center, using appropriate procedures for tightening and coding the injector in the engine control unit, if required.

A correctly selected and installed injector can restore proper engine operation, reduce jerking, and alleviate difficulties with hot and cold starting.

Injection System Diagnostics and Prevention

If you suspect diesel injection problems, it is worth consulting the educational material describing typical symptoms and consequences of neglect. Detailed information can be found in the article Diesel Injector Faults – How to Recognize Them and What Neglecting Them Entails, which discusses wear symptoms, possible engine consequences, and basic diagnostic methods.
