Additional Notes

  • Both the Q3 40 TFSI quattro (137 kW) and the Q3 45 TFSI quattro (170 kW) share an identical rear differential fluid capacity of 0.95 liter across the 2018-2021 model years.
  • A capacity of 0.95 liter is characteristic of a service fill, meaning the specified volume reflects the amount needed when topping up or refilling during routine maintenance rather than a full overhaul drain-and-fill of a larger housing.
  • The rear differential fluid interval for both quattro configurations is a check at 20,000 miles or 24 months, whichever comes first, under normal use conditions.
  • The interval is defined as a check rather than a mandatory replacement, indicating the service procedure involves inspecting fluid level and condition rather than an automatic fluid exchange at each interval.
  • The 24-month time component of the 20,000-mile/24-month interval means a time threshold applies independently of mileage accumulation, so low-mileage vehicles still reach a service point within two years under normal use.
  • The Audi Q3 F3 rear differential fluid specifications apply exclusively to quattro variants, as all-wheel-drive hardware is required for a rear differential to be present in the drivetrain.
