Purpose and Function of the Element

The presented liner is designed for installation in the left rear part of the trunk, in the area of the rear wheel arch. Its purpose is to:

• dampen sounds coming from the wheel and suspension area,
• protect the wheel arch panel from accidental impacts by transported cargo,
• visually organize the trunk space by covering structural elements,
• maintain a cohesive interior finish consistent with the original BMW standard.

Thanks to its dedicated shape, the liner works with the factory mounting points, which facilitates installation and allows for a stable seating of the element during vehicle operation.

Construction and Fit for BMW

The element has been specifically designed for the BMW 3 Series Touring body, which translates to appropriate profiling for the wheel arch and the side of the trunk. The construction of the liner includes:

• a shape tailored to the geometry of the left rear wheel arch,
• space for factory mountings and clips,
• a surface adapted for everyday trunk use.

This solution allows for maintaining compatibility with the original trunk setup, without the need for modifications or fitting universal soundproofing materials.

Condition and Benefits of Using a Used Part

The offered liner comes from the secondary market, which helps reduce the cost of repairing or replacing a missing part of the trunk upholstery. Choosing a used element offers:

• the possibility of restoring the completeness of the trunk interior after damage or modifications,
• maintaining a consistent appearance with other trim panels,
• an economically advantageous solution while preserving the original manufacturer's specifications.

For many users, this is a practical way to keep their car in good visual and functional condition, without the need to invest in new upholstery parts.

Part Selection by Numbers and Location

When selecting a trunk liner, it is crucial to pay attention to its placement on the vehicle – in this case, it is the left rear side of the body. Additionally, manufacturer markings and reference numbers can be helpful in verifying compatibility with a specific BMW 3 Series version. This approach minimizes the risk of purchasing an ill-fitting part and facilitates quick installation.
