Additional Notes

  • The Audi A4, S4, 8W (USA) semi-automatic transmission specifications are divided into two separate fluid circuits: a clutch part and a transmission part, each with distinct capacity values and service requirements.
  • The clutch part of the semi-automatic transmission carries a dry fill capacity of 4.35 liters across all A4 configurations from 2016 onward, while the service fill — the amount used when fluid is replaced without a full disassembly — is 3.5 liters, reflecting the roughly 0.85-liter volume that remains in the unit during a routine drain.
  • The transmission part of the semi-automatic unit holds 3.8 liters, a figure that appears consistently across the 140 kW, 185 kW, and 195 kW A4 variants spanning 2016-2021, with no separate service fill value listed, indicating the full 3.8 liters applies to both dry and service conditions in that circuit.
  • A fluid change interval of 40,000 miles is specified for the clutch part under normal use conditions, while the transmission part carries only a check interval of 20,000 miles or 24 months with no corresponding change interval listed in the specifications.
  • The check interval of 20,000 miles or 24 months applies uniformly to both the clutch part and the transmission part across all A4 semi-automatic configurations in the 2016-2021 range, combining a distance threshold and a time threshold under normal use.
  • The S4 3.0 TFSI quattro (260 kW) uses a conventional automatic transmission rather than the semi-automatic unit found in A4 variants, and the dry fill capacity of 8.6 liters for the S4 is substantially higher than the combined clutch and transmission part volumes of the A4 semi-automatic system.
  • The S4 automatic transmission service fill is specified as a range of 3.6 to 4.0 liters, which reflects the variability in residual fluid volume that remains in the torque converter and passages after a drain, making an exact refill quantity dependent on how thoroughly the system was emptied.
  • The S4 3.0 TFSI quattro specifications for both the 2016-2018 and 2018 onward entries share identical capacity values of 8.6 liters dry fill and 3.6-4.0 liters service fill, with a check interval of 20,000 miles or 24 months under normal use and no fluid change interval listed for either entry.
  • The A4 45 TFSI quattro at 185 kW covers 2018-2020, while the A4 45 TFSI quattro at 195 kW starts from 2020, with both sharing the same clutch part capacity of 4.35 liters dry fill and 3.5 liters service fill, and the same transmission part capacity of 3.8 liters.
  • The A4 40 TFSI at 140 kW covers 2018-2020 as a front-wheel-drive configuration, whereas the A4 40 TFSI quattro at 150 kW starts from 2020 as the all-wheel-drive variant, and both share the same semi-automatic transmission fluid capacities of 4.35 liters dry and 3.5 liters service fill for the clutch part, and 3.8 liters for the transmission part.
