Additional Notes

  • The Audi TT Roadster 8N (USA) 1.8 5V T (132 kW) front-wheel-drive variant carries a transaxle manual fluid capacity of 2 liters, a notably lower figure compared to the quattro configurations, which reflects the absence of an all-wheel-drive drivetrain adding to the fluid volume requirement.
  • Across the 1.8 5V T quattro (132 kW) variants from 1999-2002, both the 5-speed and 6-speed transaxles share an identical initial fill capacity range of 2.3-2.6 liters, meaning the gear count alone does not shift the specified fill volume for either configuration.
  • The initial fill designation on the 132 kW quattro transaxles indicates a factory or overhaul fill quantity rather than a routine service top-up, which is why a range of 2.3-2.6 liters is given rather than a fixed single value.
  • The 1.8 5V T quattro (165 kW) 6-speed transaxle specifies a fixed capacity of 2.6 liters rather than a range, in contrast to the 132 kW quattro variants, suggesting a more precisely defined fill volume for the higher-output engine's transmission.
  • The 165 kW quattro 6-speed specification appears across two separate production periods, 2000-2002 and 2002-2006, with both periods carrying identical capacity and interval figures of 2.6 liters and a 20,000-mile or 12-month check interval under normal use conditions.
  • All configurations across the 1999-2006 Audi TT Roadster 8N (USA) manual transaxle specifications share a standard check interval of every 20,000 miles or 12 months under normal use conditions.
  • A separate first-check-only interval of 15,000 miles or 12 months applies to every listed configuration, occurring earlier than the recurring normal interval and serving as a break-in inspection point for the transaxle fluid following initial operation.
  • The front-wheel-drive 1.8 5V T (132 kW) model carries the same first-check-only interval of 15,000 miles or 12 months as all quattro variants, indicating a consistent early inspection schedule regardless of drivetrain layout.
