Intended Use and Function of the Component

The sill trim is designed for installation on the left side of the 3 Series F30/F31 body, where it serves as a cover for the lower edge of the body and the sill area. It protects the side surface from:

• chips of stones and gravel thrown up by the wheels,
• mud, water, and road salt,
• minor mechanical impacts on the lower part of the body.

Thanks to its precise fit for a specific generation of BMW 3 Series, the component maintains the correct geometry and side line, which is important for both protection and the vehicle's aesthetics.

Color and Visual Fit

The factory color Schwarz 2 – 668 allows for a seamless match with the original BMW paint palette. In many cases, this enables installation without immediate repainting, reducing repair time and costs. At the same time, the characteristic side line of the 3 Series is preserved, which is important for accident repairs and restoring the car to a factory-like condition.

Technical Specifications and Installation

The component is designed as a body part to be mounted on the left side of the vehicle, taking into account factory mounting points. This ensures that:

• it fits the original brackets and sill mounts in the BMW 3 F30/F31,
• no structural modifications are required when the correct model is selected,
• the correct line and gaps between body panels are maintained.

The product has a specified weight and reference numbers, which facilitates verification of compatibility with your vehicle based on the manufacturer's catalog data.

Condition and Application in Repairs

As a used part, the side sill is suitable for use in routine maintenance and accident repairs where preserving the original BMW body structure is a priority. Choosing a used OEM part from disassembly allows for:

• maintaining factory fit to the body,
• reducing costs compared to new parts,
• maintaining compliance with the manufacturer's technical documentation.
