Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Engine Number/Engine Characteristics
Edition 08.2012, version 2.0
The label -arrow- on the upper toothed belt cover lists the engine code and the engine serial number.
The engine code can also be found on the vehicle data label and on the crankcase above the transmission.
The engine number consists of up to nine alphanumeric characters. The first part (maximum three letters) represents the "engine code", the second (six digit) is 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.
Vehicles with four-digit engine codes
Four-digit engine codes beginning with "C" are used. The first three digits describe the mechanical structure of the engine and are still stamped on the engine, as before. The fourth digit describes the engine output and torque and depends on the Engine Control Module -J623-. The engine codes and engine serial number are located on the type plate, the vehicle data label and on the engine control module.
