VW Part Numbers Explained

This blog attempts to explain the VW Group part number system. The system used dates back to the 1930s and the original designs created by Ferdinand Porsche. It may look scary, but once you learn the basics, you’ll find that the system is quite consistent and makes things easier to understand.

In addition to VW, this part numbering system is applicable to the entire Volkswagen Group, which includes SEAT, Skoda and Audi, as well as other brands such as Bentley, Bugatti, Lamborghini and Porsche.
