Find Your Mercedes Engine Number

All Mercedes vehicles made since 1959 come with a number stamped onto their engine block that will tell you just about everything you need to know about the car (this number matches the VIN).

How to Read Mercedes Engine ID Numbers

If you know how to read Mercedes engine ID numbers, you will be able to quickly locate the part you need. Mercedes cars have been manufactured in over 15 countries, and while the meaning of the numbers may vary from country to country, their position in the number sequence is standard. Knowing what part of the engine ID number to enter into a parts search engine is half the battle to finding the correct piece for your engine.

Open the hood of your Mercedes. Locate the stamped engine ID number on the top or side of the engine block, towards the rear of the engine.

The letter or letters that begin the engine ID number indicate the style of motor (sedan, touring, roadster and so on). See the chart listed in the resources below for a comprehensive definition of the letters and their meaning.

The first three numbers correspond to the type of engine that you have (diesel, oil and such). For example, an M116 type engine would have an engine ID number that begins with "116" and an M114 type engine would begin with "114."

The next three numbers indicate what version of motor it is (i.e. 2.2 lt, 2.3, 6 cyl, 8 cyl and so on). One type of motor may have many different possible versions.

The next two numbers will tell you where the engine was installed, what side driving it was for (left or right) and the type of transmission associated with it. After 1983, the second number in this set was replaced with a letter. A series of letters (like A,B,C,D,E) was assigned to each factory.

The remaining set of numbers is the specific serial number of your engine.

Tip: always verify that the number stamped on the engine block matches the VIN number attached to the frame of the car. If the engine has been replaced with a different model and you just refer to the VIN, you could waste time and money getting parts that will not work.
