Intended Use and Fitment for BMW X3 E83 LCI

The described hose is intended for BMW X3 E83 LCI models with N47 diesel engines in the 1.8d and 2.0d versions. The hose's design and geometry are adapted to the factory routing of the installation in the engine bay, which facilitates installation and reduces the risk of stress on the connections.

This component operates in a system where the following are crucial:

• stable working medium pressure,
• proper hose routing relative to other components,
• secure mounting at factory attachment points.

Thanks to this, the hose allows the system's operating parameters to be maintained in accordance with the vehicle manufacturer's specifications.

Technical Characteristics and Role in the System

The hose functions as an expansion line in a system where compensating for pressure and temperature changes is important. The appropriately selected inner diameter and connector design allow for safe medium flow while limiting the risk of leaks when installed correctly.

Key functional features include:

• factory fitment for the BMW X3 E83 LCI system with N47 engine,
• compatibility with original clamps and mounting points,
• maintenance of the correct hose routing relative to body components and engine accessories.

A hose configured this way allows for correct system operation without the need for modifications or adapters.

Original Origin and Condition of the Part

The hose comes from the BMW production line, which means factory quality and dimensional standards are maintained. As a used part, it has been sourced from a dismantled vehicle and offers a good alternative to new parts, especially for operational or restoration repairs.

Choosing an original, used hose instead of an aftermarket replacement offers several practical benefits:

• certainty of fitment for the specific engine and body version,
• compliance with factory brackets, clamps, and installation routing,
• reduced risk of installation problems due to dimensional differences.

Selection by OEM Number and Compliance with Documentation

The part has an assigned manufacturer part number and interchangeable numbers, which facilitates verification of compliance with BMW catalogs and service documentation. When selecting a hose for a specific vehicle, it is advisable to use the VIN and parts catalogs to confirm full compatibility with the given engine configuration and model year.
