Purpose and function of the fuel filler flap

The presented fuel filler flap is dedicated to the rear body section of the BMW 4 Series Gran Coupe F36. This component is responsible for the mechanical protection of the fuel filler against dirt, moisture, and mechanical damage, while simultaneously completing the side line of the vehicle, contributing to aerodynamics and visual consistency of the bodywork.

Its placement in the rear zone of the body requires maintaining appropriate rigidity and mounting stability so that the flap operates correctly with every opening and closing. The original design ensures proper fitment with the wheel arch, bumper, and fuel filler housing, which reduces the risk of rattling, looseness, or uneven gaps.

Estoril Blue Metallic B45 color and visual matching

The factory color Estoril Blue Metallic B45 is a distinctive, dynamic shade of blue used on sport-styled BMW models. Using a flap in the same paint code allows for maintaining a uniform body appearance without the need for additional painting or color matching.

For users replacing a damaged component, this is a particularly beneficial solution because it:

• minimizes the risk of shade differences between the flap and the rest of the body,
• reduces the time required to restore the vehicle to its full visual condition,
• facilitates maintaining the consistent, factory character of the Estoril Blue version.

Installation and operational characteristics

The fuel filler flap from this offer comes from the Fuel filler flaps and caps group, which means it has been designed to work with the factory opening and closing mechanism in the BMW F36 Gran Coupe. The design is intended for installation in the original mounting points, without the need for body modifications.

The used nature of the part allows for an economical replacement of a damaged element while maintaining the original manufacturer's specifications. This is a practical solution for users who want to restore the full functionality and aesthetics of the vehicle after a minor collision, act of vandalism, or local corrosion around the flap area.

Benefits of using an original BMW flap

Using an original fuel filler flap on a BMW F36 Gran Coupe brings a number of practical benefits:

• Factory fitment – maintaining the correct geometry, gaps, and body lines, without the need to adjust a universal part.
• Color consistency – the Estoril Blue Metallic B45 paint allows for maintaining a uniform look of the entire body.
• Compatibility with the existing mechanism – the flap works with the factory hinge and opening system intended for this model.
• Reasonable repair cost – a used OEM part is a compromise between quality and budget for body repairs.
