The following overview of Diagnostic Trouble Codes (DTC) applies to vehicles from the VAG group, including Volkswagen, Audi, SEAT, and Škoda.
The fault codes listed are based on the VAG standard and general SAE (OBD-II) codes, making them useful for reading errors using dedicated VAG-COM/VCDS interfaces as well as universal OBD-II scanners.
Each entry may end with a letter indicating the rules for MIL (Malfunction Indicator Lamp) activation:
MIL Activation Rules:
- A = MIL activated on first occurrence
- B = MIL activated on second occurrence
- C = Fault related to non-emission system – only service light
- D = Non-emission fault – no service light
