Additional Notes
- Across all listed Audi Q3 F3 quattro configurations, the angle gearbox and transferbox share a uniform fluid capacity of 0.9 liter, indicating a compact unit consistent with transversely mounted all-wheel-drive transfer cases of similar design.
- The 0.9 liter figure represents a service fill capacity, meaning the amount of fluid required when servicing the unit in its installed position rather than during a full bench overhaul where residual fluid retention is not a factor.
- The Q3 40 TFSI quattro at 132 kW, introduced from 2019, carries the same 0.9 liter transfer case capacity as the 140 kW variant of the same designation, despite the difference in power output between the two engine states.
- The Q3 40 TFSI quattro at 140 kW spans two separate production entries: one covering 2018-2021 and another starting from 2021, both specifying 0.9 liter for the angle gearbox and transferbox under normal use conditions.
- The Q3 45 TFSI quattro at 169 kW, listed for 2018-2020, and the 180 kW variant starting from 2021 both retain the 0.9 liter transfer case capacity, showing no change in unit size between the lower and higher output versions of the 45 TFSI engine family.
- All five configurations carry a normal use condition designation, meaning the specified 0.9 liter capacity and associated service intervals apply to standard operating environments rather than elevated-stress or severe-duty cycles.
