Mercedes A Class w177 Seat Set AMG Performance A45

Bahia Brown Leather (8V58 / 204A) | Full Equipment Specification

This is the flagship interior configuration for the W177 A-Class, specifically the A45 and A45 S AMG. While most A45 models are found in Black/Yellow or Black/Red combinations, the Bahia Brown (204A) leather package offers a sophisticated, “Executive Sport” aesthetic. It pairs the extreme lateral support of the Recaro-designed performance shells with a premium, baseball-glove brown leather typically reserved for higher-class Mercedes-Benz models.

Key Equipment Codes & Functionality

This seat set is a “high-end” configuration, featuring several luxury technologies often omitted in track-focused A45 builds:  Mercedes A Class w177 Seat Set AMG Performance A45

• AMG Performance Seats (Code 555): These are fixed-headrest bucket seats designed for maximum lateral grip. Despite their racing look, they are fully compatible with daily driving thanks to the integrated comfort features.

• Seat Climate Control (Code 401): A rare option for the bucket seats, providing both 3-stage heating and active ventilation through the perforated Bahia Brown leather centers.

• Multicontour Seat Package (Code 409): Includes electro-pneumatically adjustable side bolsters and lumbar support. This allows you to “clamp” the seat tighter to your body for track use or relax the bolsters for long-distance cruising.

• Memory Package (Code 242/275): Both driver and passenger seats are fully electric. This system stores seat position, steering column height, and exterior mirror angles.

Technical Specifications

Interior Aesthetics: Bahia Brown

The Bahia Brown colorway provides a warm, rich contrast to the W177’s high-tech MBUX “Widescreen” dashboard.

• The Finish: A mid-tone, saturated brown leather that avoids the “orange” hues found in standard saddle leathers.

• Contrast: Often paired with black DINAMICA microfibre or black leather accents (204A) and open-pore black linden wood or AMG carbon fiber trim.

Installation & Retrofit Requirements

⚠️ Expert Note on Retrofitting:

If you are installing these into an A180, A200, or A250 that originally had manual sports seats:

• Wiring Harness: You will need a significant harness upgrade to support Code 401 (Ventilation) and Code 409 (Multicontour pumps).

• Door Modules: The memory buttons (Code 275) are located on the door panels. You must replace your door cards or install the switch blocks to control these seats.

• Airbags: Ensure the seat airbags are correctly coded to your SRS module to avoid a “Restraint System Malfunction” error.
