Purpose and compatibility

This turbocharger is designed for the BMW 1 Series E81 / E87 LCI and 3 Series E90 models with the N47 diesel engine, in power versions used in models such as the 120d and 320d. Using an original component from the same design family allows for the maintenance of proper boost parameters, smooth operation, and acceleration dynamics.

By being assigned to a specific N47 engine, the turbocharger works with the factory engine control system, exhaust system and accessories, which reduces the risk of installation and calibration problems.

Technical characteristics of the turbocharger

As a component of the turbochargers and parts category, this product compresses the air drawn into the cylinders, which directly impacts the performance and efficiency of the diesel engine. The turbocharger's design is adapted to the loads typical of N47 engines, ensuring:

• stable boost pressure across the full rev range,
• appropriate response to gas at low and medium engine speeds,
• maintaining factory combustion and fuel consumption parameters,
• compatibility with the lubrication and cooling system provided for the N47 engine.

Original BMW origin means compliance with the manufacturer's requirements in terms of heat resistance, manufacturing tolerances and cooperation with control electronics.

Condition, origin and assembly advantages

The turbocharger is offered as a used OEM component. These components are disassembled, allowing for cost-effective replacement while maintaining original specifications. Compared to budget-friendly alternatives, using a factory turbocharger reduces the risk of fitment issues, leaks, or incorrect boost characteristics.

The main benefits of installing an original used turbocharger include:

• factory fit with exhaust manifold and intake,
• maintaining the standard operating parameters of the N47 engine,
• no need to modify the installation or make additional modifications,
• attractive cost-to-quality ratio compared to new components.

Application in BMW N47 diesel engines

The BMW N47 diesel engines used in the 120d and 320d models are sensitive to the quality of their components, including the turbocharger. Using the correct, original equipment component is crucial for:

• maintaining the correct power and torque,
• reducing smoke and exhaust system problems,
• correct operation of the exhaust gas recirculation system and filters,
• stable starting and smooth idling.

Selecting a turbocharger compatible with the N47 unit also reduces the risk of errors being recorded in the engine control unit and adaptation problems after installation.
