Additional Notes

  • The Audi Q3 F3 (USA) brake system capacity is 1 liter across all listed configurations, covering both the 40 TFSI quattro (137 kW) and 45 TFSI quattro (170 kW) variants. In brake fluid servicing, a 1-liter figure typically represents the total system fill volume, accounting for the master cylinder reservoir and the fluid distributed through the hydraulic lines to each caliper.
  • The check interval for the brake system is set at 10,000 miles or 12 months, whichever comes first, under normal use conditions. A mileage-and-time dual trigger like this reflects the hygroscopic nature of brake fluid, which absorbs moisture from the atmosphere over time regardless of how much the vehicle has been driven.
  • The change interval is specified at 24 months under normal use conditions for all four listed configurations. A time-based change interval independent of mileage is standard practice for brake fluid because moisture absorption degrades the fluid's boiling point over time, not solely through mechanical wear.
  • Both the 40 TFSI quattro (137 kW) and the 45 TFSI quattro (170 kW) share identical brake system specifications, including the 1-liter capacity, the 10,000-mile or 12-month check interval, and the 24-month change interval. The difference in output between the two engine variants, 137 kW versus 170 kW, does not correspond to any variation in brake fluid service requirements across the listed rows.
  • The 2018-2021 and 2021-onward entries for each engine variant carry the same brake system specifications. The presence of separate rows for the 2021 starting year indicates a production distinction recognized in the specification data, yet no difference in brake fluid capacity or service intervals is recorded between the two date ranges for either the 40 TFSI or 45 TFSI configurations.
