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
The engine number (engine code and serial number) are located next to the vibration damper on the cylinder block.
The engine number consists of up to nine characters (alphanumeric). The first part (maximum 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.
Additionally there is a sticker on the intake manifold with the engine code and serial number.
The engine code is also included on the vehicle data plate.
