Purpose and Body Fitment

The presented door is designed for installation on the front right side of the Audi A4 B8 generation body. The construction is based on factory dimensions and mounting points, which allows for maintaining correct gaps between body elements, proper geometry, and correct operation of the lock and hinges after proper adjustment.

The part belongs to the Doors and Door Panels group, meaning it is intended as an external body panel responsible for protecting the side of the cabin, bearing operational loads, and cooperating with seals and the side window.

Brilliant Black Metallic - Y9B Color

The factory paint Brilliant Black Metallic - Y9B is a dark, metallic shade of black used in Audi models, providing a subtle, elegant look to the body. Using the original color over the entire surface of the door facilitates:

• limiting the scope of painting work to potential local touch-ups,
• maintaining shade consistency with other body elements,
• preserving the vehicle's original visual character.

For body and paint shops, this means the possibility of reducing repair time and easier matching of the coating to the existing paint on the car.

Technical Characteristics and Installation

The door has been prepared as a complete door panel for installation in place of the original part. The construction is designed to work with original hinges, lock, window, and seals, which allows for maintaining the factory operating parameters of the opening and closing mechanisms after proper adjustment.

During installation, it is recommended to:

• check the body geometry in the pillar and sill area,
• precisely align the door with the fender, sill, and rear door (in 4/5-door versions),
• check the seal fit and watertightness after installation.

This approach allows for proper closing, reduced wind noise, and maintained acoustic comfort inside the cabin.

Used Condition and Service Application

The part is offered as a used part, which is a cost-effective solution for accident repairs, restorations, and bringing the vehicle back to full operational condition at controlled costs. Used OEM doors are a good basis for:

• body repairs after side damage,
• replacing a part with advanced corrosion,
• restoring the vehicle's original appearance after incorrect previous repairs.

Using an original door panel allows for compliance with the factory body manufacturing technology and facilitates further service maintenance.
