Diagnostic Trouble Codes vs P-Codes

A Diagnostic Trouble Code (DTC) is created and issued by the manufacturer and typically consists of 5 numerical digits. A P-Code is from the Society of Automotive Engineers (SAE) and helps further identify and add more detail to an issue. If your Volkswagen is experiencing an error and your OBD-II shows you a P-Code or DTC then this page should help.
