Additional Notes

  • The Audi TT Roadster 3.2 quattro (184 kW) carries the largest cooling system capacity in the lineup at 12.7 liters. By comparison, all 2.0 TFSI variants in the TT Roadster range hold 9 liters, reflecting the greater thermal mass and larger engine displacement of the 3.2-liter VR6 unit.
  • The TTS Roadster 2.0 TFSI quattro (195 kW) produced from 2008-2010 and 2010-2013 holds 8.6 liters of coolant, which is the smallest capacity across all configurations listed. Despite sharing the same 2.0 TFSI displacement as the standard TT Roadster, the TTS variant uses a different cooling system volume in those model year ranges.
  • The TTS Roadster 2.0 TFSI quattro (195 kW) for 2013-2015 shows a capacity increase to 10 liters, up from the 8.6 liters specified for the same engine in the 2008-2013 period. This represents a notable change within the same model and power output across production years.
  • All configurations from 2006-2010 carry a 12-month time limit on coolant checks regardless of mileage interval. Configurations from 2010 onward extend the time-based interval to 24 months, applying to both the normal and first check only service conditions.
  • Under normal use conditions, the coolant check interval is 20,000 miles across all listed configurations. The first check only condition reduces the mileage trigger to 15,000 miles, with the same time-based limit applying as in the corresponding normal use row for that configuration.
  • The 2.0 TFSI TT Roadster (147 kW) and the quattro variant of the same power output share identical cooling system capacities and service intervals across their respective model years, with both holding 9 liters and following the same mileage and time schedules.
  • The shift from a 12-month to a 24-month time-based interval occurs at the 2010 model year boundary for the TT Roadster 2.0 TFSI quattro (155 kW) and the TTS Roadster 2.0 TFSI quattro (195 kW). Both the normal and first check only conditions adopt the extended 24-month window from that point forward.
