Intended Use and Compatibility

The presented turbocharger is structurally adapted for popular BMW 1 Series (E81, E87N) and 3 Series (E90, E91) models with the N47 diesel engine. This makes it the right choice for replacing a worn or damaged turbo in 120d and 320d versions, ensuring the preservation of the engine's factory operating characteristics.

The component comes from the BMW line, which means compliance with factory standards for mounting, geometry, and connection points. This facilitates the mechanic's work and reduces the risk of problems with fitting the housing, pipes, and connections to the exhaust and intake systems.

Technical Characteristics of the Turbocharger

The turbocharger is designed to work with a compression-ignition engine, meaning it is adapted to high exhaust pressures and the specific torque characteristics of the Diesel unit. The design ensures appropriate boost pressure across the entire RPM range, supporting engine flexibility and proper injector system operation.

As an original part, it has an assigned OEM number and a set of interchangeable numbers, which facilitates precise identification in manufacturer catalogs or by VIN. This is particularly important for the N47 engine family, where there are structural differences between various power versions.

Condition, Service Application, and Selection by Numbers

The offered turbocharger is a used component, making it an attractive cost alternative to new parts, especially for repairs on older BMW E81/E87N and E90/E91 models. This type of part is often chosen as a base for refurbishment or direct replacement in vehicles used intensively, where a reasonable price-to-functionality ratio is key.

For correct selection, it is recommended to compare the OEM part number and reference numbers with the currently installed turbocharger or the vehicle's service documentation. In workshop practice, this helps avoid compatibility issues, differences in accessories, or different connection configurations.

Benefits of Using an Original BMW Turbocharger

Using an original turbocharger in an N47 engine brings a number of practical benefits:

• preservation of factory power and torque characteristics,
• proper cooperation with the engine control unit software,
• appropriate fit to the exhaust and intake system without modifications,
• possibility of using the existing BMW service procedure.

Thanks to this, replacing the turbo in a BMW 120d or 320d can be carried out predictably, maintaining operating parameters close to the factory configuration, which is important for both engine durability and driving comfort.
