Purpose and compatibility

The offered engine is intended for BMW 1 Series and 3 Series models of the E81, E87 LCI, and E90 generations in 118d and 318d versions with the N47 unit. Thanks to the use of the original BMW design, full compatibility with factory mounting points, fuel systems, and accessories intended for this engine series is maintained.

The unit belongs to the N47 family, which means a modern, compact design, optimized for combustion efficiency and refinement in compact and mid-size cars.

Construction and design parameters

The N47D20A engine is a four-cylinder diesel unit with direct injection, designed to run on diesel fuel. The cylinder layout and block architecture ensure a good balance between performance and economy, which is particularly important in daily operation.

The modern design of this unit allows for favorable torque characteristics while maintaining moderate fuel consumption. The engine is a popular choice for both routine repairs and modernization projects within the same BMW generation.

Condition, mileage, and benefits of purchasing a used engine

The offered unit comes from the Engines category and is a used component, which allows for a significant reduction in repair costs compared to purchasing a brand-new subassembly. The declared mileage of the engine is relatively low for this generation of units, which translates into an attractive potential for further operation with proper installation and maintenance.

Purchasing a complete used BMW engine is a solution that in many cases shortens repair time – instead of costly regeneration of a damaged block, a complete unit can be used, maintaining factory specifications and performance characteristics.

Selection by numbers and professional installation

The engine has a dedicated OEM part number and a set of interchangeable numbers, which facilitates precise identification and selection for a specific vehicle. When selecting, it is recommended to verify by VIN number and consult with a mechanic or technical advisor to confirm full compatibility with the installation in a given car.

Professional installation of this unit in a specialized service center allows for maintaining proper operating parameters, correct bleeding of the fuel system, and proper tuning with the vehicle's electronics. Thanks to this, the engine can operate stably and predictably, in accordance with the manufacturer's assumptions.
