Purpose and fitment for Audi bodywork

The presented door comes from the Audi manufacturer's range and is a structural body component designed specifically for A4 models. The placement on the right side of the vehicle, described in the Placement on vehicle parameter, ensures proper fitment with the fender, rocker panel, pillar, and factory seals. This makes it possible to restore the correct geometry of the side body section after a collision or corrosion without the need for universal solutions.

Structural and functional characteristics

The door from the Doors and door panels category plays a key role in the lateral rigidity of the body, passenger protection, and cabin sealing. The original construction ensures:

• correct window operation and compatibility with the lifting mechanism,
• proper alignment of hinges and the lock relative to the body pillars,
• factory-stamped contours and edges matched to the Audi A4 body line.

By maintaining OEM geometry, the door allows for precise adjustment of gaps between body panels, which translates into reduced wind noise and proper operation of seals and locks.

Brilliant Black Metallic color – benefits for repairs

The applied color Brilliant Black Metallic - LY9B is a factory shade used in the Audi paint palette. In practice, this means the possibility of:

• easier shade matching during spot painting or blending,
• maintaining visual consistency with other body panels in the same color,
• reducing the scope of paint work compared to components in a different shade.

For body and paint shops, this is a beneficial solution as it shortens the preparation time and makes it easier to achieve a uniform paint surface along the entire side of the vehicle.

Component condition and use in repairs

The door is offered as a used body component, which is an attractive cost alternative to new panels while maintaining the original construction. This type of part is particularly suitable for:

• post-accident repairs where full door functionality needs to be restored,
• vehicle restorations where the existing door has suffered from corrosion or mechanical damage,
• service projects where the priority is to maintain the factory character of the Audi A4 body.

By maintaining the original structural specification, the door can be integrated into the existing body layout without the need to modify mounts or pillar geometry.

Product identification and integration with search systems

The item has assigned technical parameters, such as SKU, OEM part number, and Interchangeable numbers, which facilitate precise matching in parts catalogs and search systems used by workshops and online stores. The use of standardized markings allows for quick compatibility checks with other Audi body components and minimizes the risk of selecting the wrong door panel.
