- factory-fit integration with the exhaust system in ML W166, W212, and C292 models,
- compatibility with the factory engine control unit and SCR system electronics,
- appropriate spray pattern characteristics tailored to the operating parameters of Mercedes diesel engines.
As an original part, the nozzle is designed to operate at high temperatures and in the exhaust environment, considering resistance to AdBlue crystallization and variable operating conditions.
Benefits of Using an Original Injector Nozzle
Choosing an original AdBlue injector nozzle for your Mercedes translates into a range of practical operational benefits:
- Stable AdBlue System Operation – proper fluid dosing reduces the occurrence of error messages related to the exhaust purification system.
- Improved Emission Compliance – correct AdBlue atomization helps maintain emission parameters at the level specified by the manufacturer.
- Reduced Costly Repairs – a functional nozzle lowers the risk of damage to the SCR catalyst and associated components.
- Seamless Integration with the System – factory connectors and geometry facilitate easy installation in place of a worn-out part.
Condition and Practical Application
The offered AdBlue injector nozzle is a used part, allowing for an economical replacement of a worn or damaged nozzle while maintaining the original manufacturer's specifications. This solution is particularly beneficial for vehicles used intensively, where both correct SCR system operation and cost control are important.
Before installation, it is recommended to verify the AdBlue system for leaks and the condition of the lines to ensure uniform operation of the entire dosing system and avoid recurring faults caused by other system components.
