Additional Notes

  • The Audi A6 2.7 5V Bi Turbo quattro (169 kW) carries a manual transaxle and transferbox fluid capacity of 2.3 liters, which represents a service fill figure for a combined transaxle and transferbox assembly rather than a full overhaul drain-and-fill of separate units.
  • For the 169 kW variant covering 2002-2004, the first check only interval is set at 15,000 miles or 12 months, while the normal use interval extends to 20,000 miles or 12 months, meaning the initial service occurs earlier to account for break-in contamination before settling into the standard schedule.
  • The 187 kW A6 2.7 5V Bi Turbo quattro lists a capacity range of 2.3-3.6 liters rather than a fixed value, reflecting variation between the transaxle and transferbox fill levels depending on the specific unit or fill method used during service.
  • Both the 1999-2002 and 2002-2004 production spans of the 187 kW variant share identical specifications, with a 2.3-3.6 liter capacity and a 10,000 mile or 12 month check interval under normal use conditions.
  • The 187 kW variant's check interval of 10,000 miles or 12 months is notably shorter than the 20,000 mile normal interval assigned to the 169 kW variant, indicating a more frequent service schedule despite both being classified under normal use conditions.
  • The A6 2.8 5V (142 kW) in both front-wheel-drive and quattro configurations from 1997-2001 share a fixed transaxle and transferbox capacity of 2.75 liters, a value that falls between the lower and upper bounds of the 187 kW variant's range.
  • The 2.8 5V and 2.8 5V quattro variants carry the same 10,000 mile or 12 month check interval under normal use, aligning with the 187 kW 2.7 Bi Turbo schedule rather than the longer interval seen on the 169 kW version.
