Purpose and Fitment

The presented part is a complete door panel intended for the front, left side of the vehicle, dedicated to the Audi A4 B8 generation. Its original construction ensures proper window operation, correct hinge positioning, and compatibility with factory seals and hardware, facilitating installation and subsequent adjustments.

Body Color and Finish

The door is in the factory color Lava Grey Pearl Effect – Z7L, a pearlescent shade of grey characteristic of Audi's palette. This type of pearl paint effectively masks minor dirt while accentuating the vehicle's body lines in varying light conditions. For body and paint shops, this means the possibility of precise shade matching when blending adjacent panels.

Technical Characteristics and Installation

As a component from the Doors and Door Panels category, this product is a crucial part of the vehicle's side structure, responsible for proper closing, sealing, and user safety. The design for the left side of the body allows for the retention of factory mounting points for hinges, the lock, and the door stop, simplifying the alignment of the door line with the fender, sill, and pillar.

This door comes from a used vehicle, making it an economical solution for repairs where maintaining the original geometry and panel rigidity is essential. In practice, this translates to:

• easier alignment of gaps between body panels,
• preservation of the original crease lines,
• the ability to utilize existing mounting points for accessories.

Application in Body Repairs

The left front door for Audi A4 B8 in Lava Grey Pearl Effect Z7L is suitable for both post-accident repairs and the replacement of corroded or mechanically damaged panels. Choosing an original panel helps reduce fitting time and minimizes the risk of issues with door closure, wind noise, or leaks around the seals.
