Additional Notes

  • The rear differential on the Audi Q5 2.0 TFSI quattro ultra (185 kW) carries 1.3 liters, a figure that represents a service fill capacity for the rear axle unit.
  • Several Q5 variants — the 40 TFSI quattro (150 kW), the 45 TFSI quattro ultra (185 kW and 195 kW), and the 55 TFSI e quattro (270 kW) — each list two separate rear differential capacities: 1.3 liters and 0.96 liters. The presence of two values for a single differential position typically reflects different axle hardware variants fitted across production, rather than a fill-versus-refill distinction.
  • The plug-in hybrid Q5 55 TFSI e quattro (270 kW), introduced from 2019, shares the same 1.3-liter and 0.96-liter rear differential capacity figures as the non-hybrid quattro ultra variants, indicating the rear axle assembly is not unique to the hybrid drivetrain.
  • The SQ5 3.0 TFSI quattro (260 kW) is the only configuration in these specifications to carry a front differential, with an initial fill of 1.0 liter and a refill capacity of 0.9 liters. The distinction between initial fill and refill reflects the volume difference when a filter or housing retains residual fluid during a service drain.
  • The SQ5 3.0 TFSI quattro (260 kW) rear differential is listed with three separate capacity entries: 0.85 liter, 0.95 liter, and 0.93 liter for the outer sections. The outer sections designation refers to the side chambers of a rear differential housing that are sealed separately from the central gear cavity, each requiring independent fluid servicing.
  • All SQ5 3.0 TFSI quattro (260 kW) differential capacities are marked as initial fill values, meaning the figures apply to a dry or fully drained assembly rather than a partial drain-and-refill procedure.
  • The SQ5 3.0 TFSI quattro (260 kW) entries appear under two overlapping year designations — 2017-2018 and 2018 onward — with identical capacity and interval specifications across both, indicating no change in differential fluid requirements at that model year boundary.
  • A check interval of 20,000 miles or 24 months applies uniformly across all configurations and differential positions in these specifications, under normal use conditions. The dual-unit interval means whichever threshold is reached first triggers the service check.
