Additional Notes

  • The Audi S5 Cabriolet 3.0 TFSI quattro (260 kW) transfer case carries an initial fill capacity of 1 liter, which represents the total fluid volume required when the unit is dry, such as after a complete overhaul or replacement.
  • The refill capacity for the same transfer case is 0.8 liters, reflecting the smaller volume needed during a routine fluid change when residual fluid remains in the unit after draining.
  • The 0.2-liter difference between the initial fill and refill figures is a meaningful distinction for service accuracy, as underfilling a transfer case can lead to inadequate lubrication of internal components.
  • The specified check interval for the S5 Cabriolet 3.0 TFSI quattro transfer case is every 20,000 miles or 24 months under normal use conditions, whichever comes first.
  • Both the 2017-2018 and 2018-started production entries for the S5 Cabriolet 3.0 TFSI quattro share identical capacity and interval specifications, indicating no change in transfer case service requirements across the two listed configurations.
