The component is part of the heating circuit in the rear of the body, contributing to passenger thermal comfort and even heat distribution.

Technical and Functional Characteristics

As part of the heating system, the hose is responsible for the controlled flow of heating medium between individual system components. The design, adapted for the LCI version, allows for:

• maintaining the correct hose routing relative to body and suspension elements,
• reducing stresses resulting from body flex and temperature changes,
• proper connection with factory connectors and mounting brackets.

Appropriate dimensional and shape conformity promotes system sealing and minimizes the risk of collision with other components in the rear of the vehicle.

Benefits of Using an Original BMW Part

Using a heater hose specifically designed for the BMW 3 Series E93 LCI allows for the preservation of the heating system's original operating parameters. The factory geometry and mounting points facilitate installation and reduce the need for modifications, which is important for both service repairs and restoring the configuration after a collision or intervention in the rear of the body. A used OEM part also offers a favorable compromise between quality and cost, while maintaining compliance with the manufacturer's technical documentation.

Condition and Service Application

The hose is a used part, making it an attractive solution for operational repairs where maintaining the vehicle's original specifications is a priority. It can be used as a replacement for a damaged or leaking hose in the rear right section of the heating system, restoring proper heating medium circulation in the vehicle.
