The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

TypeSpecifications
  • RS 5 Sportback 2.9 TFSI quattro (331 kW) (2018- )
  • From automatic
  • Use: Normal
  • Capacity 1 liter (Initial fill)

Additional Notes

  • The Audi RS 5 Sportback 2.9 TFSI quattro (331 kW) transfer case carries an initial fill capacity of 1 liter, which reflects 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, representing the lesser volume needed during a standard drain-and-fill service, as some residual fluid remains in the unit.
  • The 0.2-liter difference between the initial fill and refill figures is a direct consequence of fluid retained in internal passages and cavities that do not fully drain during a conventional service procedure.
  • The transfer case specification for the RS 5 Sportback 2.9 TFSI quattro applies under normal use conditions, meaning the listed capacities are associated with standard operating circumstances rather than severe or first-change-only intervals.
  • The specification note identifies the transfer case as sourced from an automatic transmission application, which is relevant context for fluid compatibility and servicing procedures tied to that unit's design.
