Audi TT, TTS, TT RS, 8J (USA)

Additional Notes

• The Audi TT 8J (USA) semi-automatic transaxle specifications list two distinct capacity figures for each configuration. The initial fill of 7 liters on the front-wheel-drive TT Coupé 2.0 TFSI (147 kW) and 6.9 liters on all quattro variants reflects the total volume required when filling a dry or fully drained unit. The refill figure of 5.5 liters, shared across every listed configuration, represents the smaller volume needed when fluid is changed without a complete drain of the torque converter or valve body passages.
• The 0.1-liter difference between the front-wheel-drive TT Coupé 2.0 TFSI (147 kW) initial fill of 7 liters and the quattro variants' initial fill of 6.9 liters corresponds to a minor difference in transaxle architecture between the two drivetrain layouts, despite both sharing the same 5.5-liter refill capacity.
• Across all configurations, the standard change interval is set at 40,000 miles, while the fluid check interval under normal use is 20,000 miles or 12 months, whichever comes first, for models produced through 2009. The 12-month time component means the interval is not purely mileage-based, and low-mileage vehicles still require periodic inspection within the calendar year.
• For the first change only condition, the check interval is shortened to 15,000 miles or 12 months, and the change interval is reduced to 35,000 miles. This earlier first-change schedule reflects the common practice of removing break-in contaminants, such as fine metallic particles generated during initial gear and clutch surface wear, before returning to the standard interval cadence.
• Beginning with the TT Coupé 2.0 TFSI quattro (155 kW) for model years 2010-2013, the time component of the fluid check interval was extended from 12 months to 24 months under both normal and first-change-only conditions. The mileage thresholds of 20,000 miles for normal use and 15,000 miles for the first change remained unchanged, meaning the revision affected only the calendar-based trigger.
• The same 24-month check interval introduced for the 155 kW quattro in 2010 carried forward to the 2013-2015 production span of both the TT Coupé 2.0 TFSI quattro (155 kW) and the TTS Coupé 2.0 TFSI quattro (195 kW). All other interval and capacity values for those later configurations remained identical to their predecessors.
• The TTS Coupé 2.0 TFSI quattro (195 kW) for 2008-2013 retains the 12-month check interval rather than the 24-month interval seen in the 155 kW quattro of the same era. Both variants share the same 6.9-liter initial fill, 5.5-liter refill, 40,000-mile change interval, and 20,000-mile check mileage threshold under normal use.
• The TT Coupé 3.2 quattro (184 kW), covering 2006-2009, carries the same 6.9-liter initial fill and 5.5-liter refill as the quattro four-cylinder variants of the same period. Interval schedules also align with those quattro configurations, with a 40,000-mile change interval and 20,000-mile or 12-month check under normal use, and a 35,000-mile first change with a 15,000-mile or 12-month check.
