Additional Notes

  • The Audi A5 Sportback 2.0 TFSI quattro (185 kW) lists two separate rear differential capacity values for 2017-2018: 0.96 liter and 0.67 liter, indicating the rear differential assembly has two distinct fill points or chambers rather than a single unified sump.
  • The same dual-capacity pattern of 0.96 liter and 0.67 liter carries over to the A5 Sportback 40 TFSI quattro (150 kW) from 2021 and the A5 Sportback 45 TFSI quattro (185 kW) for 2018-2020, as well as the 45 TFSI quattro (195 kW) from 2020, placing all four A5 quattro configurations on identical rear differential fill volumes.
  • Across all A5 Sportback quattro variants covered, the rear differential inspection interval is set at 20,000 miles or 24 months under normal use conditions, with no fluid change interval specified alongside the check interval.
  • The RS 5 Sportback 2.9 TFSI quattro (331 kW), introduced from 2018, carries a differential connected to the automatic transmission with an initial fill of 1.0 liter and a refill capacity of 0.9 liter. The 0.1-liter difference between initial and refill figures reflects the volume retained within the differential housing and associated passages after a drain, which is a common characteristic of gear oil servicing.
  • The RS 5 Sportback rear differential also lists two capacity values, 0.95 liter and 0.85 liter, consistent with the dual-point fill structure seen on the A5 Sportback variants, though the RS 5 figures are slightly higher in both positions.
  • Unlike the A5 Sportback configurations, the RS 5 Sportback rear differential specifies a fluid change interval of 60,000 miles in addition to the 20,000-mile or 24-month check interval under normal use, making the RS 5 rear differential the only application in the dataset with a defined drain-and-refill schedule.
  • The differential from the automatic transmission on the RS 5 Sportback carries only a check interval of 20,000 miles or 24 months, with no change interval listed, distinguishing its service schedule from the rear differential on the same vehicle.
