Technical Characteristics of the BMW M47N2 122 HP Engine

The presented engine belongs to the M47N2 family, used in the BMW 118d and 318d models. It is a four-cylinder diesel unit that combines economical operating characteristics with good flexibility for everyday driving. The design, based on a proven common rail injection system, ensures stable operating parameters and predictable behavior under load.

Thanks to its compact construction and refined cylinder head geometry, the engine works well with both manual and automatic transmissions used in the E87, E90, and E91 series. This unit is often chosen by BMW-specialized workshops due to its repeatable parameters and the wide availability of accessories and service parts.

Application in BMW E87, E90, E91 Models

The 204D4 engine is factory-intended for installation in the BMW 1 Series (E87) in the 118d version and in the BMW 3 Series (E90, E91) in the 318d version. This means it serves as a direct replacement base for the powertrain in these models, maintaining the vehicle's original design concept.

In workshop practice, this unit is primarily used in situations where repairing the existing engine is not economically viable. Using a complete engine block allows for reduced vehicle downtime and a narrower scope of machining work, which is particularly important for vehicles used intensively, e.g., in fleets or with high annual mileage.

Operating Parameters and Benefits of Installation

The M47N2 engine with 122 HP is valued for its balanced compromise between dynamics and fuel consumption. The four inline cylinders ensure smooth operation, and the diesel design allows for good torque in the low and mid-range RPM, translating to comfortable driving in the city and on the highway.

• Stable Torque Characteristics – facilitates smooth acceleration without the need for frequent gear changes.
• Proven M47N2 Family Design – widely known in BMW-specialized service centers, simplifying diagnostics and maintenance.
• Adequate Service Life – allows for continued use with proper maintenance.

For the user, this means the ability to restore the vehicle's full functionality while maintaining the original powertrain specifications, without the need for electronic intervention or changes to the engine control unit configuration, provided the selection is made according to the engine designation.

Selection by OEM Number and Interchangeable Numbers

The engine has an assigned OEM part number and a set of interchangeable numbers, which facilitates precise unit identification in BMW catalogs and service systems. When selecting, it is recommended to verify compatibility by OEM number and the 204D4 engine designation, as well as compare with the vehicle's documentation.

If in doubt, it is advisable to use the VIN or full part number selection procedure. This is described in detail in the expert guide: Why Buy Used Gearboxes and Engines – Facts Instead of Myths, which discusses the practical aspects of purchasing used powertrains, including the importance of OEM and reference numbers.

Condition, Origin, and Practical Workshop Application

The offered engine from the BMW Engines category is a dismantled unit intended for reinstallation after prior verification by a workshop. Such units are often chosen by BMW-specialized workshops as an economical alternative to brand-new engine blocks, especially for vehicles with higher mileage.
