The Mercedes-Benz vehicle type, parts, service groups and information classifications

If you’re a relative newcomer to working on Mercedes-Benz vehicles, you may be surprised at how many numbers you run into. Besides the fact that the company uses numbers for the sales descriptions of their cars, unlike most domestic or Asian carmakers, these sales numbers are not even the ‘real’ numbers! What’s more, everything else also fits into a numbering system that gradually developed over time to encompass everything on the vehicles, one that includes within the system provision for classifying vehicle technologies not yet invented.

First are the car model numbers. These correspond to the chassis/frame construction of the vehicle, not the sales number. The sales number usually, though not always, reflects in a stylized way the displacement of the engine in liters. Since the same engines are often used in different body styles, you can find more than one kind of vehicle with, say, the number 300 in its sales designation. On the following page are the service group and parts classifications. Every part and every piece of service information fits here in the parts bin or the service literature under that number.
