Additional Notes

  • All quattro configurations across the Audi TT, TTS, and TT RS 8J (USA) share a uniform transfer case (angle gearbox / transferbox) fluid capacity of 0.9 liter, applying equally to the 2.0 TFSI 147 kW, 155 kW, 195 kW, and 3.2 quattro 184 kW variants.
  • The 0.9 liter figure represents a service fill capacity, meaning the volume required when topping up or replacing fluid during a scheduled check rather than a full mechanical overhaul of the unit.
  • A first check only interval of 15,000 miles is specified for all listed configurations, set earlier than the standard 20,000-mile normal interval. A first check interval is typically used to assess a newly manufactured or recently serviced unit for contamination, wear particles, or seal integrity before returning to the standard schedule.
  • The normal use interval for all listed configurations is 20,000 miles, paired with either a 12-month or 24-month time limit depending on the model year group.
  • The 2.0 TFSI quattro at 147 kW (2006-2008) and the updated 147 kW variant (2008-2010) both carry a 12-month time component alongside the 20,000-mile normal interval, meaning whichever limit is reached first would trigger a check.
  • Starting with the 2.0 TFSI quattro at 155 kW (2010-2013), the time component of the normal interval extended from 12 months to 24 months, a change that also applies to the first check only interval for the same variant, which moved from 12 months to 24 months at 15,000 miles.
  • The 24-month time interval introduced with the 155 kW variant from 2010 carried forward into the 2013-2015 production period for both the 155 kW TT Coupé and the 195 kW TTS Coupé, aligning the two models on the same schedule during that period.
  • The TTS Coupé 2.0 TFSI quattro at 195 kW followed the 12-month time interval during 2008-2013, then transitioned to the 24-month time interval for 2013-2015, mirroring the pattern seen in the lower-output 2.0 TFSI variants.
  • The 3.2 quattro at 184 kW (2006-2009) retains the 12-month time component for both the normal and first check only intervals, consistent with the other configurations produced during the same period.
