Kit Purpose and Characteristics

The BMW F30 330d Diesel N57N Injector System Kit includes components responsible for precise fuel delivery in a modern diesel engine. The design is based on OEM BMW solutions, ensuring proper fitment for the N57N unit and compatibility with the factory engine control unit maps.

The injector system in this model operates under high pressure, making the use of original components crucial for maintaining stable engine operation, correct fuel atomization, and reducing smoke and power loss.

Benefits of Using Genuine BMW Injector Nozzles

Choosing OEM BMW injector nozzles translates into several practical benefits for everyday use:

• Factory Fitment – The geometry of the nozzle tips and their operating characteristics are in line with the N57N engine's requirements, facilitating the maintenance of the correct air-fuel mixture.
• Stable Idle Operation – Proper fuel metering reduces vibrations, fluctuating RPMs, and issues with starting both warm and cold engines.
• Improved Engine Smoothness – Correct fuel atomization promotes even combustion, leading to reduced noise and more predictable throttle response.
• Protection of Other Components – A functional injector system minimizes the risk of excessive strain on the turbocharger, DPF filter, and exhaust gas recirculation system.

Professional Fitment and Interchangeable Numbers

The offered kit comes from the BMW OE line, signifying compliance with factory quality and construction standards. The injector system components have assigned part numbers and interchangeable numbers, allowing for precise verification against the BMW catalog or service software before installation.

This solution enables mechanics or diagnosticians to unequivocally confirm compatibility with a specific N57N engine version in the BMW F30 330d, reducing the risk of errors in component selection and speeding up the repair process.

Condition, Application, and Installation Recommendations

This is a used injector system kit, intended for users and workshops seeking genuine BMW components at a reasonable price. This type of solution is suitable for both routine repairs and comprehensive engine overhauls where restoring proper fuel system operation is required.

Due to the critical role of injector nozzles for engine safety and longevity, installation is recommended at a specialized service center, using appropriate diagnostic tools and injector adaptation procedures in the engine control unit. Correct calibration allows for the full utilization of the offered kit's potential and minimizes the risk of recurring faults.

Diagnostics and Technical Knowledge

Before replacing injector system components, it is advisable to perform detailed diagnostics, including a leak-off test, fuel correction analysis, and reading control unit error codes. This helps confirm whether the injector nozzles are the source of the problems or if other fuel or intake system components are at fault.
