Application in BMW diesel models

The presented injector is designed for diesel engines used in popular BMW 1, 3, 5, and X3 series models, including M47N2 and M57N units. This solution is dedicated to high-pressure injection systems, where precise fuel atomization in the combustion chamber and dose repeatability across the entire load range are critical.

Thanks to a design compliant with manufacturer standards, this component allows for maintaining factory engine performance parameters, such as idle smoothness, throttle response, and stability at higher RPMs.

Technical characteristics of the injector

The injector operates within a diesel fuel supply system, which requires resistance to high pressure and repeatability of injection cycles. The applied technology enables:

• precise fuel dosing depending on engine load and RPM,
• proper fuel atomization in the combustion chamber,
• maintenance of stable engine performance parameters under typical road conditions.

The original BMW origin ensures compatibility with factory engine management and proper cooperation with other components of the injection system.

Condition of the item and benefits of installation

The offered injector is used, which allows for an economical repair of the fuel system while maintaining the original manufacturer's specifications. This solution is particularly beneficial when servicing several cylinders simultaneously, where it is essential to maintain consistent performance parameters across all injectors.

Choosing an original BMW component from the Other category allows for maintaining compatibility with the factory installation, without the need for adaptation or modification of wiring harnesses and controllers. For workshops and users, this means predictable installation time and easier diagnostics of potential faults in the future.

Part selection by numbers and compatibility

The injector has an assigned OEM part number and associated interchangeable numbers, which facilitates unambiguous identification of the component in BMW catalogs and service systems. When selecting, it is always recommended to compare the part number with the one currently installed in the vehicle and verify it against the specific M47N2 or M57N engine version.

This helps reduce the risk of incompatibility and ensures proper cooperation with the existing injection system, engine controller, and accessories.
