Additional Notes

  • The Audi A5 2.0 TFSI quattro (155 kW) carries two separate automatic transmission fluid entries for 2008-2013: one for the transaxle at 10.4 liters initial fill, and one for the transmission at 9 liters initial fill with a refill range of 3.6-4 liters. The distinction between transaxle and transmission here reflects two physically separate fluid circuits, each with its own capacity specification.
  • Initial fill values represent the total fluid volume required when a unit is dry, such as after a complete overhaul or replacement. Refill values, like the 3.6-4 liter range listed for the A5 2.0 TFSI quattro (155 kW) transmission, reflect the smaller volume needed after a routine fluid drain where residual fluid remains in the torque converter or passages.
  • The A5 2.0 TFSI quattro (162 kW) from 2013-2017 shows a reduced initial fill of 8.6 liters compared to the 9 liters specified for the earlier 155 kW variant, while the refill range of 3.6-4 liters remains unchanged across both power outputs.
  • A notable interval difference appears between the 155 kW and 162 kW A5 variants. The 155 kW model carries a 12-month time interval alongside the 20,000-mile check interval, while the 162 kW model extends the time component to 24 months, indicating a longer calendar-based service window for the later engine.
  • The A5 3.2 FSI quattro (195 kW) transaxle holds 10.4 liters at initial fill across both the 2007-2009 and 2009-2010 production periods, with check intervals of 20,000 miles or 12 months under normal use conditions in both ranges.
  • The RS 5 4.2 FSI quattro (331 kW) uses an S tronic semi-automatic transmission with two distinct fluid circuits: a clutch part and a transmission part. The clutch part carries a 7.5-liter initial fill and a 6.7-liter refill, while the transmission part holds a fixed 4.35 liters with no separate refill value listed.
  • For the RS 5 4.2 FSI quattro (331 kW) S tronic clutch part under normal use, a fluid change is specified at 40,000 miles. Under the first change only condition, that interval shortens to 35,000 miles, reflecting an earlier service requirement for the initial fluid life cycle. This pattern applies identically across both the 2012-2013 and 2013-2015 production ranges.
  • The RS 5 4.2 FSI quattro (331 kW) S tronic transmission part specifies a change interval rather than a check interval: 20,000 miles under normal use and 15,000 miles under the first change only condition. This contrasts with the clutch part, which carries both check and change intervals.
  • The S5 3.0 TFSI quattro (245 kW) S tronic clutch part shares the same 7.5-liter initial fill, 6.7-liter refill, 20,000-mile or 24-month check interval, and 40,000-mile change interval as the RS 5 4.2 FSI quattro (331 kW) across both the 2012-2013 and 2013-2017 production periods.
  • The S5 3.0 TFSI quattro (245 kW) S tronic transmission part lists a 4.35-liter capacity with a check interval of 20,000 miles or 24 months, whereas the RS 5 4.2 FSI quattro (331 kW) transmission part specifies a change interval at the same mileage point rather than a check interval.
  • The S5 4.2 FSI quattro (260 kW) transaxle carries a 10.4-liter capacity across both the 2007-2009 and 2009-2012 production periods, with no separate refill value listed. The absence of a refill figure, unlike the transmission entries for the 2.0 TFSI variants, is consistent with transaxle designs where full drain-and-fill procedures are standard practice.
  • Across the S5 4.2 FSI quattro (260 kW) transaxle entries, the first check only condition shortens the check interval from 20,000 miles to 15,000 miles while the 12-month time component remains the same. The same first-check mileage reduction of 5,000 miles appears in the A5 2.0 TFSI quattro (155 kW) and A5 3.2 FSI quattro (195 kW) transaxle and transmission entries.
