| The engine number (“engine code” and “serial number”) is engraved on the front of the engine block, gearbox side, below the thermostat housing. |
| The engine number consists of up to nine characters (alphanumeric). The first part (maximal 3 characters) makes up the “engine code”, and the second part (6 characters), the “serial number”. If more than 999,999 engines with the same engine code are produced, the first of the six characters is replaced with a letter. |
