Additional Notes

  • The angle gearbox, also referred to as a transferbox, is the component in a quattro all-wheel-drive system that redirects torque from the transversely mounted drivetrain to the rear axle. All Audi TT and TTS Roadster quattro configurations covered here share a uniform transfer case fluid capacity of 0.9 liter, which is consistent with a service fill rather than a full overhaul volume.
  • Every configuration carries two distinct check intervals tied to use condition. The first check only interval is set at 15,000 miles, while the normal use interval is set at 20,000 miles. The first check only interval applies exclusively to the initial service event, after which the standard 20,000-mile normal interval governs subsequent checks.
  • For the TT Roadster 2.0 TFSI quattro (147 kW) covering 2007-2009 and 2009-2010, both the normal and first check only intervals carry a 12-month time limit alongside the mileage trigger, meaning whichever threshold is reached first determines when the check is due.
  • The TT Roadster 3.2 quattro (184 kW) from 2006-2009 follows the same 12-month time-based interval structure as the 147 kW 2.0 TFSI variants of the same era, with a normal check at 20,000 miles or 12 months and a first check only at 15,000 miles or 12 months.
  • Starting with the TT Roadster 2.0 TFSI quattro (155 kW) from 2010 onward, the time-based component of the service interval extended from 12 months to 24 months for both the normal and first check only conditions. The TTS Roadster 2.0 TFSI quattro (195 kW) adopted the same 24-month interval structure from 2010 onward as well.
  • The TTS Roadster 2.0 TFSI quattro (195 kW) from 2008-2010 retains the 12-month interval structure, placing it in the same service cadence as the lower-output 147 kW TT Roadster variants of the overlapping period, despite the difference in power output.
  • Across all configurations from 2010-2013 and 2013-2015, whether TT or TTS, the transfer case fluid capacity remains at 0.9 liter and the check intervals remain at 20,000 miles or 24 months for normal use and 15,000 miles or 24 months for the first check only, indicating no specification change between those two consecutive production periods.
