Engine number
WARNING: This page does not describe the selected car, but rather 20 other vehicles, including the 2009 Volkswagen Golf, 2008 Volkswagen Golf, 2007 Volkswagen Golf, 2006 Volkswagen Golf, and 2005 Volkswagen Jetta. However, it is still accessible from the selected car via links, so may be relevant.
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.
