Technical Characteristics of the AdBlue Injector Nozzle

The presented component belongs to the category of injector nozzles, responsible for the precise delivery of AdBlue solution into the exhaust stream. The original Mercedes design ensures the correct spray pattern, which is crucial for the effective operation of the SCR catalyst and compliance with emission standards.

The AdBlue injector is designed to operate in demanding thermal and chemical conditions, which is why its geometry and materials are adapted for contact with urea solution and high exhaust temperatures. This allows the NOx reduction system to maintain stable performance over a longer service life.

Intended Use and Fitment for Mercedes V177

The AdBlue Injector for Mercedes V177 was developed as part of the factory system, ensuring full compatibility with the vehicle's electronics and engine control unit software. Using an original injector nozzle minimizes the risk of ECU errors, SCR system malfunction warnings, and power loss due to limp-home mode.

This part is suitable for users who want to restore the proper functioning of the exhaust gas purification system after a failure or wear of the existing injector. Choosing a part from the same product line as the factory-fitted one simplifies installation and helps maintain predictable engine performance.

Benefits of Using an Original Injector Nozzle

Replacing a worn AdBlue injector with an original component from the injector nozzles category offers a range of practical benefits:

• Stable SCR System Operation – proper AdBlue atomization promotes effective nitrogen oxide reduction.
• Reduced Risk of Diagnostic Errors – compatibility with the factory control unit minimizes incorrect readings and dashboard warnings.
• Maintenance of Emission Parameters – correct dosing of the reducing agent helps meet environmental requirements and homologation standards.
• Improved Engine Smoothness – a functional exhaust gas purification system reduces the need for limp-home mode, contributing to a smoother driving experience.

Product Condition and Service Application

The offered AdBlue injector is a used part, providing a cost-effective solution for users seeking an original component at a more economical price. Such elements are often preferred in professional workshops and by discerning mechanics who favor original design solutions over aftermarket alternatives with uncertain parameters.

The choice of a used injector nozzle is particularly important for vehicles used intensively, where both repair cost and maintaining consistency with the original exhaust system design are key considerations.

Technical Support and Additional Resources

When diagnosing and replacing components of the dosing system, it is advisable to pay attention to the overall condition of the injectors and the symptoms of their wear.
