Additional Notes

  • The Audi S4 Cabriolet (253 kW) carries a 9.8-liter automatic transaxle initial fill capacity, which reflects the volume required when filling a dry or fully drained unit rather than a partial service top-up.
  • Under normal use conditions, the automatic transaxle on the S4 Cabriolet (253 kW) is subject to a 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 the same 2003-2005 S4 Cabriolet transaxle, meaning the initial inspection after a fill is scheduled earlier than subsequent normal-use checks.
  • Both the normal and first-check-only intervals share the same 9.8-liter initial fill figure, confirming the capacity value is consistent regardless of which service interval schedule is being followed.
  • The 12-month time component appears in both interval entries for the 2003-2005 S4 Cabriolet, indicating that elapsed time carries equal weight alongside mileage as a trigger for the transaxle check.
