Additional Notes

  • The Audi A4 2.0 T (147 kW) in front-wheel-drive form carries a manual transaxle fluid capacity of 3 liters, while both the A4 2.0 T quattro (147 kW) and A4 3.2 quattro (188 kW) share a larger 3.5-liter capacity, reflecting the additional volume required by the quattro drivetrain's transaxle layout.
  • The RS 4 4.2 V8 quattro (309 kW) and S4 4.2 V8 quattro (253 kW) both specify a 3.2-liter capacity for the manual transaxle, positioning them between the front-wheel-drive 2.0 T and the quattro four-cylinder variants in terms of fluid volume.
  • The S4 4.2 V8 quattro (253 kW) capacity of 3.2 liters is labeled as an initial fill, indicating the figure applies to a first-time factory or assembly fill rather than a routine service top-up or refill following a drain.
  • The RS 4 4.2 V8 quattro (309 kW) transaxle note specifies a combined manual/transferbox unit, meaning the 3.2-liter capacity covers a shared housing that integrates both the manual gearbox and the transfer case for the quattro system.
  • Across all configurations in the 2005-2008 range, the normal-use check interval is set at 20,000 miles or 12 months, whichever comes first, applying uniformly regardless of engine output or drivetrain type.
  • A separate first-check-only interval of 15,000 miles or 12 months is specified for every configuration listed, with the fluid capacity remaining identical to the normal-use figure for each respective variant. The earlier interval on a first-check-only basis is a common practice to catch any initial wear particles or contamination that accumulate during the break-in period of a new transmission.
  • The RS 4 4.2 V8 quattro (309 kW) shares the same 20,000-mile/12-month normal check interval and 15,000-mile/12-month first-check interval as the A4 and S4 variants, despite the higher-output engine and the combined transaxle/transferbox assembly.
