Characteristics of the BMW N47N turbocharger

This turbocharger was designed specifically for the N47N engine in the upgraded BMW 320d and 520d models. The OEM design ensures proper boost pressure, proper throttle response, and compatibility with the factory engine management and exhaust system.

By maintaining the original geometry and exhaust gas flow parameters, the turbocharger supports the proper operation of the injection system, exhaust gas recirculation system, and engine control unit mapping. This is particularly important in modern diesel engines, where improperly adjusted boost can result in power loss, increased fuel consumption, or diagnostic errors.

Construction and fit for BMW E90 LCI and F10

As a turbocharger and parts item, this model is designed to be mounted to the factory mounting points in the engine compartment. This means maintaining:

• consistent spacing of oil and cooling connections,
• factory connection to the exhaust manifold and intake,
• cooperation with the serial N47N engine accessories.

This adjustment reduces the need for assembly modifications and allows for the efficient restoration of full functionality of the supercharging system in the BMW 3 Series E90 LCI and 5 Series F10 with the 320d/520d engine.

Used condition - conscious choice of OEM

The turbocharger offered is in used condition, providing an attractive cost alternative to new OEM components. Choosing an original, used component allows you to maintain the engine's factory operating characteristics while reducing the costs of repairing or overhauling the engine.

Before installation, standard maintenance activities are recommended, such as inspecting the lubrication system, oil lines, and intake manifolds, as well as verifying the proper operation of the oil filter and the quality of the lubricants used. A properly prepared system significantly extends the life of the turbocharger and stabilizes boost parameters.

Benefits of using an original BMW turbocharger

The use of the original turbocharger in the N47N engine brings a number of practical benefits:

• Factory fit – compatible with the standard BMW E90 LCI and F10 configuration, with no hardware adaptation required.
• Stable operating parameters – maintaining the power and torque characteristics provided by the manufacturer.
• Better cooperation with electronics – correct communication with sensors and engine control unit, lower risk of diagnostic errors.

Selection by OEM number and interchangeable numbers

This turbocharger is assigned an OEM part number and a set of interchangeable numbers, making it easy to precisely identify and match your specific N47N engine version.
