Alphanumeric Volkswagen Engine Codes were stamped on VW Engine cases at time of car manufacture to convey information about the size and specs of the engine. Because VW offered multiple engine sizes and made changes to their engines independently of model changes, they used Engine Codes instead of relying on VIN numbers for this purpose. There is some engine information that can be derived from VW VIN Numbers for pre-1968 vehicles.
From the first 1 or 2 digits of a Volkswagen Engine Code you can derive the approximate year and engine size. The remainder of a VW Engine Code is essentially a serial number.
