The engine number (Code letters and Serial number) can be found on the flange between engine/transmission.

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 letters/numbers), 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 by a letter.

Additionally there is a sticker on the toothed belt guard containing the engine code and serial number.

The engine code is also included on the vehicle data plate.
