The Audi TT, like most modern vehicles, is OBD2 compliant. However, the specific model year determines the extent of its compliance. This article clarifies which Audi TT models are OBD2 compliant and provides information on OBD2 compliance in various regions.
OBD2 Compliance in the Audi TT
All Audi TT models sold in the United States from 1996 onwards are fully OBD2 compliant. This is due to federal regulations mandating OBD2 compliance for all vehicles sold in the US after that year.
For Audi TT models sold in the European Union, the compliance year depends on the fuel type:
- Petrol (Gasoline) Engines: Full OBD2 compliance began in 2001 for all models and 2000 for new types.
- Diesel Engines: Full OBD2 compliance started in 2004 for all models and 2003 for new types.
