Understanding the nuances of Mercedes-Benz W124 side mirror compatibility can be crucial for maintenance, repair, or restoration. While the mirror glass and housing across W124 coupe, convertible, sedan, and wagon models share similarities in shape and even asymmetry, the key difference lies in their mounting bases at the doors. This variation is primarily due to the windshield angle and attachment points differing between body styles.
W124 Mirror Basics: Housing and Mounting
It’s essential to recognize that despite the shared appearance of the mirror glass and housing units, they are not universally interchangeable across all W124 variants. The crucial factor determining compatibility is the mounting base, which is specifically designed for either coupe/convertible or sedan/wagon models.
Sedan and Wagon (1986-1995) Mirror Specifications
For W124 sedans and wagons produced from 1986 up to the 1992 model year, the driver’s side mirrors were manually adjustable. These early manual mirrors are also compatible with W201 models. Passenger side mirrors with electric adjust from this period are also interchangeable with W201 models.
However, for later W124 sedan and wagon models (1993-1995 US model years), the electric adjust driver’s door mirrors became a W124-specific part, no longer shared with the W201.
Here are the specific part numbers for sedan and wagon mirrors:
- Sedan/wagon driver’s door mirror (manual adjust – 1986-1992): 124 810 49 16
- Sedan/wagon driver’s door mirror (electric adjust – 1993-1995): 124 810 77 16
- Sedan/wagon passenger door mirror: 124 810 52 16
Coupe and Convertible Mirror Specifications
The situation for coupe and convertible models is slightly different. The “coupe” style driver’s door mirrors are exclusively applicable to specific early W124 coupe models: the 124.051 (M103 engine) and 124.052 (M104 engine). The W124 convertible (124.066) also utilized the coupe mirrors, but with a VIN breakpoint that affects driver’s side mirror selection.
The passenger-side mirror, however, is universally compatible across all W124 coupe and convertible variants (124.051, 124.052, and 124.066).
Below are the part numbers for coupe and convertible mirrors:
- Coupe & early convertible (up to chassis #855528) driver’s door mirror: 124 810 57 16
- Late coupe & late convertible (from #855529) driver’s door mirror: 124 810 81 16
- Coupe & convertible passenger door mirror: 124 810 61 16
Conclusion: Ensuring Correct W124 Mirror Fitment
When sourcing replacement side mirrors for your Mercedes-Benz W124, it’s vital to identify your vehicle’s body style (sedan, wagon, coupe, or convertible) and model year. Pay close attention to whether you require a driver’s or passenger side mirror, and if your vehicle is an early or late model, especially for coupe and convertible driver’s side mirrors. Utilizing the correct part numbers ensures proper fitment and maintains the original aesthetics and functionality of your Mercedes W124.
