Additional Notes

  • The Audi SQ5 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 direct result of fluid retained in internal passages and components that does not fully drain during a standard service procedure.
  • The transfer case fluid check interval for the SQ5 3.0 TFSI quattro (260 kW) is set at 20,000 miles or 24 months under normal use conditions, whichever comes first.
  • Both the 2017-2018 and the 2018- production variants of the SQ5 3.0 TFSI quattro (260 kW) share identical transfer case capacities and check intervals, indicating no specification change was introduced between those two entries.
