Purpose and function of the component

The presented roof trim is dedicated for installation on the left side of the BMW F30 series body, in the roof area. It is responsible for the aesthetic finish of the roofline and is part of the roof rail system, which can be compatible with transport accessories intended for this model. Thanks to the preservation of the original geometry, it ensures proper adhesion to the roof panel and compatibility with factory mounting points.

Liquid Blue Metallic B40 color scheme

The finish in the Liquid Blue Metallic – B40 shade allows for maintaining a uniform body appearance without the need for additional painting when matching vehicles with the same paint code. This solution is particularly beneficial when replacing a damaged roof rail, as it helps reduce repair time and maintains visual consistency with other body components.

Installation characteristics

The roof trim has been designed as a component compliant with BMW factory specifications, which facilitates installation in place of the original part. Proper fitment to the roof edge and correct positioning on the vehicle's left side promotes the maintenance of tightness and the proper operation of seals in this area. When replacing, it is recommended to use appropriate fasteners consistent with the vehicle manufacturer's solutions.

Condition and service application

The component comes from the secondary market, making it an attractive alternative for post-accident repairs, body visual corrections, or restoring the vehicle to a factory-like condition. It can be used both in body and paint repairs and when replacing individual roof rail components if the original part has suffered mechanical damage or operational wear.

Integration with other BMW protective and decorative trims
