Volkswagen Group vehicles — including VW, Skoda, Audi, and SEAT — share a common electronic architecture based on VW’s proprietary VAG-COM protocol. To diagnose a Volkswagen Taigun, Virtus, Polo, or Tiguan properly, you need a scanner with deep VAG protocol support — otherwise you will miss the majority of fault codes that exist outside standard OBD2.
