Application and compatibility

The B47D20B engine has been designed as a diesel unit for modern BMW 1, 3, and 4 series F-generation LCI models. The inline four-cylinder design provides a balanced combination of performance and economy, and the architecture compatible with the F20/F30/F32 platform facilitates installation in vehicles factory-equipped with this engine family. As a result, it is an appropriate choice for replacing the unit in 125d, 325d, and 425d cars, while maintaining the original drive characteristics.

Construction and technical specifications

The unit belongs to the new generation of BMW B47 diesel engines. The four-cylinder layout ensures a good balance between weight, efficiency, and smooth operation, and the modern design of the block and cylinder head is prepared for integration with advanced control systems and accessories used in the 125d, 325d, and 425d versions. As a complete engine block, it serves as a solid base for transferring accessories from the previous unit, which allows for maintaining the vehicle's equipment configuration.

Condition, origin, and benefits of choosing a used engine

The offered engine comes from the Engines category and is a used component, which allows for significantly reducing repair costs compared to purchasing a brand-new unit or a full overhaul. The engine's mileage is known, which facilitates the assessment of its potential for further operation in the vehicle. Choosing an original BMW engine from the same design family minimizes the risk of mechanical and electronic fitment issues and also facilitates workshop work during installation.

For drivers considering the purchase of a used engine, an expert guide describing the facts and myths associated with such a decision will be particularly useful – more information can be found in the article Why it is worth buying used gearboxes and engines – facts instead of myths, where topics such as selection by OEM numbers and cost aspects are discussed.

Practical installation and maintenance tips

Before installation, it is recommended to perform standard service procedures, such as replacing consumables and checking the accessories transferred from the old unit. The four-cylinder design of the B47D20B engine is well-known to workshops specializing in the BMW brand, which facilitates the replacement process and subsequent maintenance. A properly selected and installed engine restores full drivetrain functionality, maintaining the driving characteristics typical of the 125d, 325d, and 425d models.
