Additional Notes

  • Both the A4 Cabriolet 2.0 quattro (147 kW) and the 3.2 quattro (188 kW) share an identical automatic transaxle initial fill capacity of 9.8 liters across the 2005-2008 model years, meaning the displacement difference between the two engines does not produce a variation in fluid volume for the transmission system.
  • The 9.8-liter figure is listed as an initial fill, which refers to the quantity of fluid introduced when the transmission is filled from a dry or overhauled state, rather than the smaller top-up volume typically associated with a routine fluid level service.
  • Under normal use conditions, the fluid check interval for both the 2.0 quattro and 3.2 quattro automatic transaxle is set at 20,000 miles or 12 months, whichever comes first.
  • A separate first check only interval of 15,000 miles or 12 months applies to both configurations, establishing an earlier inspection point before the standard normal-use schedule takes over for subsequent checks.
