Additional Notes

  • The Audi RS 3 2.5 TFSI quattro, introduced in 2021, carries a transfer case refill capacity of 0.8 liter. A refill figure represents the serviceable fluid volume returned during a drain-and-fill procedure, as opposed to a total overhaul or dry-fill capacity, which would account for all internal passages and cavities in a fully disassembled unit.
  • The 0.8 liter refill specification applies under normal use conditions, meaning standard driving environments without the added mechanical stress associated with severe-duty classifications such as towing, off-road operation, or repeated short-trip cycles.
  • The transfer case in question is identified specifically as an angle gearbox or transferbox, a unit that redirects drivetrain torque to the rear axle as part of the quattro all-wheel-drive system. The 0.8 liter figure is tied directly to that component and is distinct from any front or rear differential fluid capacities.
