Additional Notes

  • Across all listed configurations, the Audi A5, S5, RS 5 transfer case carries an initial fill capacity of 1 liter, which represents the total fluid volume required when filling a dry or overhauled unit from empty.
  • The refill capacity of 0.8 liters applies to all four configurations and reflects the working volume used during a standard service drain-and-fill, accounting for residual fluid that remains in the unit.
  • The 0.2-liter difference between the initial fill and refill figures is consistent across both the RS 5 Coupé 2.9 TFSI quattro and the S5 Coupé 3.0 TFSI quattro, indicating a shared transfer case design between the two powertrains.
  • The RS 5 Coupé 2.9 TFSI quattro (331 kW) covering model years 2017-2018 carries a fluid check interval of every 20,000 miles or 24 months under normal use conditions.
  • The S5 Coupé 3.0 TFSI quattro (260 kW) specifies the same 20,000-mile or 24-month check interval under normal use conditions for both the 2017-2018 entry and the entry starting from 2018.
  • The RS 5 Coupé 2.9 TFSI quattro entry starting from 2018 lists no check interval in the specifications, whereas the 2017-2018 entry for the same model specifies a 20,000-mile or 24-month interval.
  • The RS 5 Coupé 2.9 TFSI quattro is noted specifically as drawing transfer case fluid from the automatic transmission, a detail that distinguishes how fluid supply is sourced in the drivetrain layout.
