Additional Notes

  • The rear differential fluid capacity across all Audi TT and TTS Roadster quattro configurations covered in these specifications is 0.95 liter. A sub-liter capacity is characteristic of a compact rear differential unit, as found in Haldex-based all-wheel-drive systems used in transverse-engine quattro applications of this generation.
  • Every configuration listed carries two distinct check intervals tied to use condition. The first-check-only interval is set at 15,000 miles, while the normal ongoing interval is set at 20,000 miles. The shorter first-check interval reflects standard break-in practice for differential fluid, where initial gear wear particles are expected to contaminate the fluid earlier in the service life.
  • For the 2.0 TFSI quattro at 147 kW (2007-2009) and 184 kW 3.2 quattro (2006-2009), both the normal and first-check-only intervals carry a 12-month time limit alongside the mileage figure. Whichever threshold is reached first would trigger the service, meaning low-mileage vehicles driven infrequently are still subject to an annual check.
  • Beginning with the 2.0 TFSI quattro at 155 kW (2010-2013), the time-based component of the check interval extends from 12 months to 24 months. The same 24-month time limit applies to the TTS Roadster 2.0 TFSI quattro at 195 kW from 2010 onward, representing a notable shift in the calendar-based service cadence relative to earlier model years.
  • The mileage figures for both the normal and first-check-only intervals remain unchanged across all model years and power outputs listed. The 20,000-mile normal interval and 15,000-mile first-check interval are consistent whether the engine is the 147 kW, 155 kW, 184 kW, or 195 kW variant.
  • The TTS Roadster 2.0 TFSI quattro at 195 kW shares identical rear differential fluid capacity and interval specifications with the TT Roadster 2.0 TFSI quattro at 155 kW across the overlapping 2010-2013 and 2013-2015 periods, despite the meaningful difference in power output between the two variants.
