Purpose and fitment

The presented item is a rear left door designed for the Audi A4 / S4 B9 Avant estate body style. Its placement on the rear left side of the vehicle ensures a precise fit to the factory hinge mounting points, lock, and seals, which facilitates installation and subsequent adjustment.

Its original Audi origin helps maintain the correct body geometry, proper panel gaps, and compatibility with factory windows, trim, and fittings.

Color and finish Mythical Black Metallic - Y9T

The door is finished in Mythical Black Metallic - Y9T, a dark, metallic shade of black characteristic of the Audi palette. The metallic paint provides depth and an attractive light-reflecting effect, making it easier to visually match the existing vehicle paintwork.

In many cases, using a component in the same paint code allows for limiting bodywork to minor touch-ups and polishing, which reduces repair time and costs while maintaining a consistent look across the entire side of the vehicle.

Technical characteristics and installation

The door belongs to the Doors and door panels group, meaning it is a key structural element of the side body. The design provided by the vehicle manufacturer ensures appropriate rigidity, compatibility with factory hinge mounting points, and proper operation of the window and seals.

The component is prepared for installation on the rear left side of the vehicle, which allows for:

• maintaining the correct geometry of the door opening,
• proper operation of the lock and closing mechanism,
• consistent connection with the sill, pillar, and rear fender.

As a used part, the door is a cost-effective solution for post-accident repairs or replacing corroded components, allowing for high quality at a reasonable budget.

Benefits of using original Audi doors

Using original doors in Mythical Black Metallic - Y9T for the Audi A4 / S4 B9 Avant offers a range of practical benefits:

• Factory fitment – maintaining body lines, panel gaps, and mounting points consistent with the manufacturer's design.
• Color consistency – compliance with the Y9T paint code makes it easier to achieve a uniform side surface without visible shade differences.
• Repair cost optimization – a used body component often reduces the scope of body and paint work compared to repairing heavily damaged doors.
• Seamless integration – the ability to use existing vehicle components mounted in the door (depending on the specific car configuration).
