Additional Notes

  • The Audi TT and TTS 8J manual transaxle capacity is listed at 2.3 liters across all covered configurations, applying equally to both the 2.0 TFSI quattro (147 kW) and the 3.2 quattro (184 kW) Roadster variants for 2006-2009.
  • A 2.3-liter figure for a manual transaxle represents a service fill volume, meaning the amount of fluid needed to bring the unit to the correct operating level rather than a full overhaul or dry-fill quantity.
  • The normal-use check interval for the manual transaxle is set at 20,000 miles or 12 months, whichever comes first, and applies to both the 2.0 TFSI quattro (147 kW) and the 3.2 quattro (184 kW) Roadster.
  • A separate first-check-only interval of 15,000 miles or 12 months is specified for both Roadster configurations, meaning the initial fluid inspection occurs earlier than subsequent normal-use intervals.
  • The 5,000-mile difference between the first-check-only interval (15,000 miles) and the normal recurring interval (20,000 miles) reflects a standard break-in practice, where early fluid inspection accounts for metal particles and contamination generated during initial gear wear.
  • Despite the significant power difference between the 147 kW 2.0 TFSI and the 184 kW 3.2 engine, the manual transaxle fluid capacity and both check intervals are identical across the two variants.
