Purpose and function of the component

The fuel filler flap plays an important protective and aesthetic role in the rear fender area. It protects the filler neck from external contaminants, ensures the tightness of the filler area, and contributes to the consistent look of the vehicle's side profile. In the event of mechanical damage, corrosion, or paint loss, using an original salvaged flap allows you to restore the vehicle's factory appearance while maintaining correct geometry and fitment.

Color and paint matching

The presented component is factory-painted in the Hainan Blue – X5K shade, used in selected Audi Q3 8U configurations. This ensures that:

• it is possible to maintain a uniform body color without additional paint work (subject to paint code compatibility),
• you reduce the risk of shade differences resulting from individual color matching in a paint shop,
• you maintain a consistent, factory-finish surface character.

To confirm color compatibility, it is recommended to compare the vehicle's paint code with the code assigned to this flap.

Technical characteristics and installation

The flap has been designed as a body component dedicated to the Audi Q3 8U generation, which means it maintains the correct geometry, mounting points, and compatibility with the factory hinge mechanism and opening limiter. Its original Audi origin ensures:

• proper fitment with the bodywork without the need for modifications,
• maintenance of correct gaps between body panels,
• stable operation of the flap during opening and closing of the filler.

The component is a salvaged part, which in practice means a beneficial combination of original manufacturing quality and an attractive price compared to a new part.

Use in service and repairs

The fuel filler flap in Hainan Blue is particularly useful in situations where there has been:

• mechanical damage to the flap (cracks, dents, scratches),
• local corrosion or paint peeling around the filler area,
• a need to replace the component after a collision or body repair.

Using an original flap from the same model generation allows you to reduce repair time and avoid problems with fitting aftermarket parts of uncertain specifications.

Technical support and selection by part numbers

Selecting the correct fuel filler flap for an Audi Q3 8U should be based on vehicle data and catalog numbers, which minimizes the risk of purchasing an incompatible part. If you have any doubts regarding compatibility, information from service documentation or a consultation with a technical advisor may be helpful.
