Additional Notes

  • The manual transaxle capacity across all listed configurations is 3.2 liters, a figure consistent with a transaxle unit that integrates the transmission and differential into a single housing, requiring a larger fluid volume than a standalone gearbox.
  • The Audi RS 4 Cabriolet (309 kW) and S4 Cabriolet (253 kW) share an identical 3.2-liter transaxle fluid capacity, indicating the same manual transaxle unit is used across both power outputs.
  • Under normal use conditions, both the RS 4 Cabriolet (309 kW) and S4 Cabriolet (253 kW) carry a fluid check interval of 20,000 miles or 12 months, whichever comes first.
  • A separate first-check-only interval of 15,000 miles or 12 months applies to both the RS 4 Cabriolet (309 kW) and S4 Cabriolet (253 kW), reflecting an earlier inspection point during the initial break-in period of the transaxle fluid.
  • The first-check-only interval is 5,000 miles shorter than the standard normal-use interval, meaning the transaxle fluid condition is evaluated sooner during early service life before the longer recurring schedule takes effect.
  • The RS 4 Cabriolet (309 kW) specifications cover model years 2007-2009, while the S4 Cabriolet (253 kW) specifications cover 2006-2008, representing a partial overlap in production years between the two variants.
