Additional Notes

  • All rear differential entries across the TT, TTS, and TT RS Roadster 8J9 lineup share a capacity of either 0.95 liter or 1 liter, which are typical service fill volumes for a compact rear differential unit rather than a full overhaul or dry-fill quantity.
  • The Audi TT Roadster 2.0 TFSI quattro at 155 kW (2010-2014) is the only configuration in the lineup specifying a rear differential capacity of 1 liter, setting it apart from all other variants, which are rated at 0.95 liter.
  • The TT Roadster 2.0 TFSI quattro at 147 kW covers 2008-2010, while the 155 kW version covers 2010-2014, reflecting a power output change at the 2010 model year boundary that also corresponds to the slight capacity difference between the two.
  • The TTS Roadster 2.0 TFSI quattro appears in two output ratings, 195 kW and 200 kW, both spanning 2008-2014, and both share the same 0.95 liter rear differential capacity under normal use conditions.
  • The TT RS Roadster 2.5 TFSI quattro (2009-2014) and the TT RS Roadster plus 2.5 TFSI quattro (2011-2014) are the only configurations in the lineup that carry an explicit service interval specification, with a check interval of 24 months or 30,000 km under normal use conditions alongside the 0.95 liter capacity.
  • The TT Roadster 2.0 TDI quattro appears across two overlapping year ranges, 2008-2010 and 2010-2014, both listing a rear differential capacity of 0.95 liter with no interval specification, suggesting a generational or emissions-regulation variant distinction rather than a capacity change.
  • The TT Roadster 3.2 quattro (2007-2010) carries the same 0.95 liter rear differential capacity as the four-cylinder variants despite housing a larger displacement engine, indicating the rear differential unit itself was not upsized for the V6 application in the 8J9 body.
