  • Q3 2.0 TFSI quattro (147 kW), 8UG (2014-2018)
  • Angle gearbox
  • Use: Normal
  • Capacity 0,9 liter
  • Check 20000 miles/ 24 months

Additional Notes

  • The transfer case fluid capacity for the Audi Q3 2.0 TFSI quattro (147 kW), 8UG is 0.9 liter, which represents a service fill volume typical of a compact angle gearbox or transferbox unit rather than a full overhaul drain-and-fill quantity.
  • The 0.9 liter figure applies specifically to the angle gearbox and transferbox assembly, a distinction noted in the specifications that separates this fluid system from the main transmission or differential circuits.
  • The inspection interval for transfer case fluid is set at 20,000 miles or 24 months, whichever comes first, under normal use conditions across the 2014-2018 model years.
  • The 24-month time limit paired with the 20,000-mile mileage threshold means the interval is dual-trigger, so elapsed time alone can initiate a service requirement even when mileage accumulation is low.
  • The normal use condition designation tied to the 20,000-mile/24-month interval reflects standard operating assumptions, as opposed to severe-duty cycles that would typically shorten fluid service intervals in comparable drivetrain systems.
