Additional Notes

  • The rear differential fluid capacity across the Audi TT 8J quattro lineup holds at 0.95 liter for every configuration listed, spanning the 2.0 TFSI 147 kW, 2.0 TFSI 155 kW, 3.2 quattro 184 kW, TTS 2.0 TFSI 195 kW, and TT RS 2.5 TFSI 265 kW variants. A sub-liter capacity of this kind is characteristic of a compact rear differential unit rather than a transaxle or transfer case assembly.
  • The TT RS Coupé 2.5 TFSI quattro (265 kW) is the only configuration in the lineup carrying a front differential specification, with a capacity of 0.9 liter. All other quattro variants in the 8J range list only a rear differential, reflecting a difference in drivetrain architecture between the TT RS and the rest of the range.
  • The front differential on the TT RS 2.5 TFSI quattro holds 0.9 liter, which is 0.05 liter less than the 0.95 liter rear differential capacity on the same vehicle. Both positions share identical check intervals of 20,000 miles or 24 months under normal use conditions.
  • A first-check-only interval of 15,000 miles or 12 months applies to the rear differentials of the TT Coupé 2.0 TFSI 147 kW (2006-2010), the TT Coupé 3.2 quattro 184 kW (2006-2009), and the TTS Coupé 2.0 TFSI 195 kW (2008-2013). The first-check interval is shorter than the standard recurring check, serving as an early inspection to confirm fluid condition after initial break-in.
  • Starting with the 2.0 TFSI 155 kW variant introduced for 2010-2013, the time-based component of the check interval extended from 12 months to 24 months for both normal and first-check-only conditions. The same 24-month time interval carries through to the 155 kW (2013-2015) and TTS 195 kW (2013-2015) configurations.
  • The TTS Coupé 2.0 TFSI quattro 195 kW follows a split in service intervals across its production span. The 2008-2013 build uses a 12-month time limit alongside the mileage trigger, while the 2013-2015 build shifts to a 24-month time limit, matching the pattern seen in the later 155 kW TT Coupé variants.
  • The mileage-based check intervals remain consistent across all years and configurations: 20,000 miles for normal use and 15,000 miles for the first check only. The variation between earlier and later production years is confined entirely to the time-based component of the interval.
  • The 0.95 liter rear differential capacity figure remains unchanged across the full 2006-2015 span covered by the specifications, regardless of engine output differences ranging from 147 kW to 265 kW. Capacity figures at this level typically reflect a service fill rather than a dry-fill overhaul quantity, as overhaul fills account for additional fluid retained in bearings and passages during disassembly.
