Purpose and fitment

The presented door has been designed as an Audi body component, with precise fitment to the body geometry and factory mounting points. The placement on the vehicle is specified as the rear, left side, which facilitates clear identification of the correct installation location on the body.

The original Audi origin promotes the maintenance of proper structural rigidity, correct gaps between body panels, and compatibility with factory seals, hinges, and door hardware.

Characteristics of Brilliant Black Metallic - Y9B paint

The Brilliant Black Metallic - Y9B color is a distinctive metallic black used in Audi models, providing an elegant, understated look to the body. Using the original shade makes it easier to match the existing vehicle paint coating and minimizes the scope of any necessary paintwork.

The metallic structure of the paint promotes uniform light reflection, which improves the visual consistency of the entire side of the vehicle after repair. For body and paint shops, this means predictable color behavior during corrections and polishing.

Function and installation benefits

The rear left door plays a key role in protecting passengers and ensuring the lateral rigidity of the body. Replacing a damaged element with an original Audi component allows for the restoration of:

• the correct side body line,
• stable mounting of windows and seals,
• proper operation of the lock and hinges after the correct transfer of equipment.

The element from the Doors and door panels category provides a solid base for further installation of interior equipment, upholstery, and electrical wiring, in accordance with the configuration of a specific Audi A4 unit.

Used condition and practical aspects

The offered component is in used condition, which in practice means a favorable compromise between the cost of repair and maintaining the original quality of the structure. For many users and workshops, this is a sensible solution for post-accident repairs, restorations, or returning a vehicle to full operational efficiency.

Choosing used body parts helps reduce production waste and aligns with the principles of a circular economy.
