Purpose and Technical Characteristics

The presented fuel injector for Volkswagen Golf 5G 1.6 TDI CLHA belongs to the injector nozzles category and works with a Diesel fuel supply system. The component's design is adapted to the operating parameters of the 1.6 TDI engine, enabling proper fuel spray formation, adequate atomization, and maintaining stable injection pressure across the entire load range.

The injector is factory-designed for the CLHA unit's specifications, ensuring compatibility with engine control unit maps, cold start fuel quantity characteristics, and correction quantities. The appropriately selected geometry of the nozzle tip supports even mixture combustion and reduces the risk of localized combustion chamber overheating.

Benefits of Using an Original Injector Nozzle

Using an original injector in the 1.6 TDI CLHA engine allows for maintaining the factory operating parameters of the powertrain. Key benefits include:

• Stable Idle Operation – proper fuel dosing reduces engine vibrations and uneven running.
• Improved Throttle Response – correct diesel atomization supports dynamic acceleration across the full RPM range.
• Reduced Exhaust Smoke – precise injection minimizes unburnt fuel, contributing to a cleaner exhaust.
• Protection of Associated Components – correct fuel dose and spray pattern promote longer lifespan for pistons, valves, and the diesel particulate filter.

Component Condition and Service Application

The offered injector nozzle is a used part, providing a cost-effective service solution for users seeking an original component at a reasonable price. This type of element is particularly useful for:

• Single-cylinder repairs, when only one injector has been damaged,
• Comparative diagnostics, when a workshop needs a functional injector for swap testing,
• Restoring factory configuration after unsuccessful fuel system modifications.

Before installation, it is recommended to perform standard workshop procedures, including checking operating parameters on a test bench and verifying seal integrity, to ensure correct operation in the specific vehicle.

Diagnostics and Prevention of the Injection System

For 1.6 TDI CLHA diesel engines, it is crucial to react quickly to the first signs of injector malfunction, such as starting difficulties, power loss, increased smoke, or characteristic knocking under load. To better understand the symptoms of wear and the potential consequences of neglect, it is advisable to consult the guide: diesel injector faults – symptoms, consequences, and diagnostics. This will help in selecting the appropriate repair strategy and correctly assessing the necessity of replacing a specific injector.
