Purpose and compatibility

Thanks to the use of OEM markings and interchangeable numbers, the part can be precisely matched to a specific vehicle version, reducing the risk of errors when selecting the component and simplifying the work of the workshop.

Original BMW origin ensures correct operating parameters, appropriate boost characteristics and compatibility with the factory engine management, without the need for software modifications or installation of additional adapters.

Technical and construction characteristics

The turbocharger belongs to the turbochargers and components category, meaning it is responsible for compressing the air drawn into the diesel engine's cylinders. Its design is based on the classic turbine and compressor system, working in conjunction with the exhaust and intake systems of the N47 engine.

The key features of this turbocharger are:

• Diesel engine match – geometry and performance matched to the torque characteristics of the N47 units.
• Compatibility with factory equipment – can be installed in place of a worn turbocharger without interfering with the engine design.
• OEM markings and reference numbers – making it easier to identify parts by VIN or manufacturer catalogs.

By maintaining the original specifications, the turbocharger allows you to maintain factory performance, operating smoothness and fuel consumption at the level specified by the manufacturer.

Condition, service use and installation benefits

The part is offered as a used BMW turbocharger, which represents a reasonable compromise between repair costs and maintaining the original design. This type of solution is often chosen by BMW specialists and by knowledgeable users looking for a proven component at a more attractive price than a new replacement.

Replacing a worn turbocharger with a functional element of this type allows you to:

• restore proper dynamics when accelerating,
• reduce the smoke and power drops typical of a damaged supercharger,
• reduce the risk of further damage to engine accessories resulting from incorrect boost pressure.

Due to the nature of the part used, it is recommended to have it installed by a specialized service center, which will verify the correct installation, tightness of the intake system and proper lubrication of the turbocharger after starting the engine.

Selection by numbers and substantive support

This turbocharger is assigned an OEM part number and a set of interchangeable numbers, enabling precise matching based on manufacturer catalogs or VIN. In practice, this means that compatibility with a specific BMW 1, 3, or 5 Series with the N47 engine can be clearly verified before purchase, minimizing the risk of making the wrong choice.
