BMW 3 Series F31 F31N LCI Sound Insulation Trunk Rear Right O/S 7234602

The BMW F31 F31N LCI Insulation Sound Deadening Mat Right Rear Trunk Trim Panel is an original soundproofing component designed for the right rear section of the trunk in the 3 Series Touring body style. Engineered to fit the specific interior geometry, this mat helps reduce road noise, suspension operation sounds, and vibrations transmitted from the wheel arch into the cabin. This enhances acoustic comfort and the overall refinement of the vehicle's operation, especially when driving with a loaded trunk.

Application and Function in BMW F31 Body Style

The presented sound deadening mat is dedicated to the rear right trunk trim panel in BMW 3 Series Touring models of the F31 / F31 LCI generation. Its placement in the wheel arch and trunk side trim area effectively dampens:

• tire noise and rear wheel rolling sounds,
• suspension operation sounds and mounting component noises,
• resonances of the body panels in the rear section of the vehicle.

Thanks to its precise fit for the specific body style, the mat integrates with the factory upholstery panels, without interfering with mounting points, clips, or the trunk's internal systems.

Construction and Acoustic Properties

The insulation is designed as a component with specific thickness and material density, allowing for effective absorption and dissipation of sound waves within the range typical for road noise. The mat's structure is adapted for use in the rear of the vehicle, where variable loads and local temperature fluctuations occur.

Key structural advantages include:

• precise fit to the shape of the trunk's side section,
• stable support for the side upholstery,
• reduction of vibrations transmitted from the wheel arch to the interior.

This solution supports the overall acoustic integrity of the vehicle body and helps maintain the characteristic BMW level of cabin quietness.

Installation and Compatibility

The sound deadening mat is intended for installation in the rear right section of the vehicle, within the trunk's side trim area. The component's design allows for installation at the factory-provided mounting points, which simplifies service work and reduces the risk of improper placement.

When selecting insulation, it is advisable to consider:

• body style compatibility (F31 / F31 LCI),
• vehicle placement – right rear side,
• fit with existing trunk trim and upholstery.

A correctly chosen component ensures the continuity of factory soundproofing and the aesthetic finish of the trunk interior.

Characteristics of a Used Part

The offered insulation is a used part, sourced from disassembly. This type of component retains its acoustic properties while offering an economical solution for post-accident repairs, replacement of damaged soundproofing, or completing missing trunk trim elements.

Choosing an original, used mat helps maintain material consistency with other interior components and reduces the risk of fitment issues typical of universal aftermarket parts.

Integration with Other BMW Interior Elements

The rear trunk trim insulation works in conjunction with upholstery panels, accessory mounts, and body structural elements. A correctly installed mat:

• stabilizes the trunk's side panel,
• reduces creaks and rattles resulting from the movement of plastic trim,
• contributes to maintaining uniform soundproofing throughout the rear of the vehicle.

This is particularly important in vehicles used for long journeys, where cabin acoustic comfort directly impacts driver and passenger fatigue.

Technical Support and Parts Knowledge

When selecting components for advanced premium models like the BMW 3 Series, it is beneficial to utilize reliable sources of knowledge about the construction of modern vehicles. In the context of comparing technical solutions used in different brands and performance versions, it is worth familiarizing yourself with material describing the construction of powertrains, braking systems, and chassis – a good starting point would be the article Audi RS vs. Other Models – What Lies Under the Hood and Chassis?, which illustrates how manufacturers differentiate equipment and components based on the version.
