Purpose and vehicle placement

The presented door is designed for installation on the left rear side of the body, allowing for precise reconstruction of the vehicle's side zone following a collision, corrosion, or other operational damage. The construction is based on factory mounting points, ensuring that the correct geometry of the hinges, lock, and fitment to the wheel arch and sill is maintained.

Its original Audi origin means compliance with factory dimensional tolerances, which facilitates the adjustment of gaps between body panels and reduces the need for additional bodywork.

Brilliant Black - LY9B color

The door is finished in Brilliant Black - LY9B, characteristic of many Audi A4 configurations. The paint provides color depth and an aesthetic gloss, while also serving as a good base for potential shade matching when painting adjacent elements.

For body and paint shops, this means the possibility of reducing surface preparation time and easier achievement of a consistent visual effect along the entire side of the vehicle.

Structural characteristics

As an element from the Doors and door panels group, the product serves as a complete load-bearing base for other components mounted in the door – windows, lock, wiring harness, or seals (mounted separately, according to the vehicle configuration). The rigid structure ensures proper hinge operation and correct closing, which is important for both user comfort and acoustic sealing, as well as protection against weather conditions.

The used nature of the part allows for an economical repair while maintaining original material quality and construction, which is particularly important in post-accident repairs where both cost and compliance with factory solutions matter.

OEM number selection and compatibility

The door was manufactured as an OEM component for Audi, which facilitates identification and selection for a specific body version. When matching to the car, it is worth verifying compatibility with the Vehicle Identification Number (VIN) and equipment configuration to ensure the correct transfer of accessories from the previously installed door.

Application in Audi body repairs

The door in Brilliant Black - LY9B will work well both for local repairs after minor collisions and for larger bodywork jobs where replacing the entire panel is necessary. The original construction allows for maintaining the side line of the body and also facilitates the correct installation of seals and moldings, which translates into reduced wind noise while driving.
