Volkswagen Workshop Service and Repair Manuals

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.

→ The engine number ("Code letters" and "Serial number") can be found on the front of the cylinder block at the gearbox end below the thermostat housing.

Additionally there is a sticker on the toothed belt guard with "Engine code" and "Serial number".

The engine code is also on the vehicle data plate and on the crankcase above the gearbox.
