Additional Notes

  • The Audi S4 Cabriolet 8H / B6 (USA) with the 253 kW engine carries a manual transaxle and transferbox fluid capacity of 3.2 liters, which reflects a service fill volume rather than a full overhaul or dry fill quantity.
  • Under normal use conditions, the transaxle and transferbox fluid check interval is set at 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 3.2-liter transaxle and transferbox fill, meaning the initial inspection after a fluid service occurs earlier than subsequent normal-use checks.
  • The 253 kW S4 Cabriolet uses a combined transaxle and transferbox note for both interval entries, indicating the 3.2-liter capacity figure covers both units together rather than each as a separate service point.
  • The 5,000-mile difference between the first-check-only interval and the normal-use interval reflects a break-in period practice, where newly filled transmission fluid is inspected sooner to account for initial wear particles and settling before the standard schedule takes over.
