Additional Notes

  • The Audi A5 2.0 TFSI quattro (185 kW) covering 2017-2018 carries a rear differential capacity of 0.67 liter, a relatively small figure consistent with a compact rear differential unit in an all-wheel-drive passenger car application.
  • The A5 40TFSI quattro ultra (150 kW) from 2021 onward lists two separate rear differential capacities: 0.96 liter and 0.67 liter. The presence of two distinct values for the same model indicates two different differential assemblies are fitted across production variants of that configuration.
  • The same dual-capacity pattern appears on the A5 45 TFSI quattro (195 kW) from 2020 onward, where rear differential capacities of 0.96 liter and 0.67 liter are both specified. By contrast, the earlier 185 kW version of the 45 TFSI quattro (2018-2020) lists only the single 0.67 liter figure.
  • All A5 rear differential entries across every configuration and model year share an identical check interval of 20,000 miles or 24 months under normal use conditions. No fluid change interval is specified for any A5 variant.
  • The RS 5 Coupé 2.9 TFSI quattro (331 kW) introduces a third differential location not present in A5 entries: the differential sourced from the automatic transmission. For both the 2017-2018 and 2018 onward production ranges, the initial fill capacity for that unit is 1.0 liter, while the refill capacity is 0.9 liter. The 0.1 liter difference between initial fill and refill reflects fluid retained within the unit during a partial drain rather than a full overhaul.
  • The RS 5 Coupé rear differential is specified with two capacity values, 0.95 liter and 0.85 liter, across both the 2017-2018 and 2018 onward entries. As with the A5 dual-capacity entries, these figures correspond to different differential assemblies used within the same model designation.
  • Unlike the A5 and S5 rear differential entries, the RS 5 Coupé 2.9 TFSI quattro rear differential carries a mandatory fluid change interval of 60,000 miles in addition to the standard 20,000-mile or 24-month check. A fluid change interval at 60,000 miles under normal use conditions reflects a more demanding duty cycle associated with the higher-output RS variant.
  • The S5 Coupé 3.0 TFSI quattro (260 kW) shares the same differential-from-automatic initial fill of 1.0 liter and refill of 0.9 liter seen on the RS 5 Coupé, across both the 2017-2018 and 2018 onward entries. The rear differential capacities of 0.95 liter and 0.85 liter also mirror the RS 5 Coupé figures exactly.
  • The S5 Coupé rear differential entries do not include a 60,000-mile change interval, unlike the RS 5 Coupé entries that share otherwise identical capacity values. Both models specify only the 20,000-mile or 24-month check interval for the rear differential under normal use conditions.
