Purpose and fitment

The presented door is a factory Audi body component, designed to function in the front, left part of the vehicle. The OEM construction ensures proper window guidance, correct hinge positioning, and compatibility with factory locks, seals, and fittings characteristic of this generation of Audi A4.

The placement on the vehicle defined as front – left side ensures that the geometry of the panel, the character line, and the shape of the window frame are consistent with the manufacturer's factory specifications, which facilitates precise fitting with the fender, rocker panel, and A-pillar.

Brilliant Black Metallic - LY9B color

The door is finished in Brilliant Black Metallic - LY9B, a popular metallic black used in many Audi A4 units. Thanks to this, in many cases, post-accident repair is possible with a limited scope of painting, which shortens vehicle downtime and reduces the cost of the entire operation.

Metallic black provides an aesthetic, understated look to the body, masks minor dirt well, and is easy to maintain with proper care of the paint coating. For body and paint shops, this means predictable paint behavior during any potential blending of adjacent elements.

Component characteristics and service application

As an item from the Doors and door panels category, the product is a key component of the side body structure, responsible for properly closing the door opening, cabin tightness, and correct window operation. Using the original Audi construction reduces the risk of problems with lock adjustment, leaks, or improper operation of internal mechanisms.

The used door is particularly useful for post-accident repairs when the priority is to maintain factory body geometry and reduce costs compared to new components. In workshop practice, such a solution allows for:

• shortening repair time thanks to the ready-made panel structure,
• easier alignment with factory mounting points,
• limiting the scope of bodywork to the necessary minimum.

Used condition and economic benefits

The item is offered in used condition, which is a reasonable compromise between cost and functionality. In many cases, this allows for restoring full efficiency and aesthetics of the side body part without the need to invest in a new component. For the user, this means real savings while maintaining the original Audi construction.

Choosing a used door is particularly beneficial for repairing vehicles a few years old, where it is crucial to match the quality of the repair to the current market value of the car, while maintaining safety and the correct operation of body components.
