Purpose and compatibility

This turbocharger belongs to the Turbochargers and Parts category and is designed to work with BMW N47 diesel engines, including those used in the 120d, 320d, and 520d. The OEM design ensures proper operating parameters, adequate boost pressure, and proper integration with the factory engine management system.

Thanks to the use of a unique solution, the engine's operating characteristics are preserved – from starting, through flexibility in the mid-range, to stable performance under higher loads. This is particularly important in cars used daily, where predictable drivetrain behavior and consistent performance are essential.

Construction and operating parameters

As an OEM component, the turbocharger is designed for the specific geometry of the exhaust manifold, intake system, and cooling system in BMW N47 engines. The appropriately selected rotor diameter, hot and cold side housing, and factory actuator settings translate into:

• stable boost pressure across the full rev range,
• correct cooperation with the engine controller software,
• maintaining factory fuel consumption while maintaining stock performance.

The system is designed to operate with diesel fuel, which means adequate resistance to exhaust gas temperature, proper starting characteristics and adaptation to typical operating conditions of BMW diesel engines.

Condition, origin and benefits of choosing a used turbocharger

The turbocharger offered is used, disassembled, and represents an attractive alternative to new components. Choosing a pre-owned original component allows you to retain the factory design at a lower cost, which is particularly beneficial when repairing older vehicles.

Installation and service aspects

Due to its factory origins, the turbocharger is designed for installation in the intended BMW engines without the need for mechanical modifications. When replacing it, we recommend:

• checking the lubrication system (oil condition, pipe patency),
• checking the tightness of the intake and intercooler,
• verification of the exhaust system for excessive flow resistance.

Correct installation and adherence to service procedures are crucial for the durability of the turbocharger and the stable operation of the diesel engine in everyday use.
