generations, and variants they produce. Each component, from engine parts to electronic systems, has its own unique OE number to ensure compatibility with specific models. While it's difficult to pinpoint an exact number of OE numbers since it continuously grows with new models and updates, here’s a rough breakdown: 1. Engine Parts Thousands of OE numbers cover parts like pistons, gaskets, fuel injectors, turbochargers, etc., each specific to engine variants (e.g., M274, OM642). 2. Transmission and Drivetrain Each transmission type (e.g., 7G-Tronic, 9G-Tronic) and related parts (clutch, driveshafts) have their own OE numbers. 3. Electrical Components Complex systems like ECUs, sensors, wiring harnesses, and lighting systems contribute thousands more OE numbers. 4. Suspension and Braking Systems OE numbers for shock absorbers, control arms, brake pads, and discs, covering models like the G-Class, E-Class, S-Class, etc. 5. Body Parts and Interior Components Doors, mirrors, dashboards, and infotainment systems are all categorized under separate OE numbers. In total, the number of Mercedes-Benz OE numbers could easily reach tens of thousands, considering each specific model (e.g., C-Class, E-Class, S-Class, G-Class) and the unique configurations (AMG models, engine sizes, etc.). These OE numbers are essential for ensuring that replacement parts match the exact specifications of the vehicle. |
