Additional Notes

  • The Audi Q5 Sportback 45 TFSI quattro ultra (185 kW) lists two distinct rear differential capacities under normal use conditions: 1.3 liters and 0.96 liters. The presence of two separate figures for the same differential position indicates that different rear differential assemblies or variants are fitted to vehicles within the same engine and trim configuration.
  • The SQ5 Sportback 3.0 TFSI quattro (260 kW) carries specifications for both a front and a rear differential, reflecting the demands of a full quattro drivetrain with discrete front and rear axle gear units rather than a combined transaxle arrangement.
  • For the SQ5 Sportback front differential, the initial fill capacity is 1.0 liter, while the refill capacity is 0.9 liters. The distinction between an initial fill and a refill figure is common when a filter or housing retains a residual volume of fluid after a drain, meaning a service refill does not restore the full factory-fill quantity.
  • The SQ5 Sportback rear differential is listed with three separate capacity values under normal use: 0.85 liter, 0.95 liter, and 0.93 liter for the outer sections. All three are designated as initial fill figures, pointing to physically different rear differential assemblies or sub-chambers that require individual filling procedures.
  • The 0.93-liter figure for the SQ5 Sportback rear differential is specifically attributed to the outer sections, which suggests a multi-chamber rear differential design where the outer sections are serviced independently from the central housing.
  • Across all six rows in the Q5 Sportback FYT specifications, the service check interval is uniformly set at 20,000 miles or 24 months under normal use conditions, applying equally to both the 45 TFSI quattro ultra and the SQ5 Sportback 3.0 TFSI quattro configurations.
