Additional Notes

  • The Audi A6 Allroad 4B (USA) carries a 9-liter initial fill capacity across all listed automatic transmission configurations, a figure that reflects a full overhaul or dry-fill scenario where the torque converter, valve body, and transmission pan are all emptied before fluid is introduced.
  • Refill capacity, which applies to a partial fluid exchange rather than a complete overhaul, varies by engine variant. The 4.2 5V quattro (221 kW) covering 2003-2005 specifies a refill range of 2.6 to 4 liters, while the Bi Turbo 2.7 5V quattro (169 kW) covering 2002-2005 specifies a fixed 2.6-liter refill, and both 187 kW Bi Turbo variants specify a refill range of 3.5 to 4 liters.
  • The use of a range rather than a fixed refill value for the 4.2 5V quattro and the 187 kW Bi Turbo variants indicates that the actual fluid recovered during a drain can vary, so the refill quantity is adjusted accordingly to reach the correct operating level.
  • Under normal use conditions, the automatic transmission fluid check interval for all listed configurations 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 is specified for every listed configuration. A first check only interval is an earlier one-time inspection point, typically used to verify fluid condition and level after initial break-in before returning to the standard recurring interval.
  • The 187 kW Bi Turbo 2.7 5V quattro appears across two distinct year ranges, 2000-2002 and 2002-2004, both sharing identical capacity and interval specifications, meaning the same service parameters apply despite the separate production period entries.
  • The 169 kW and 187 kW variants of the Bi Turbo 2.7 5V quattro differ in their refill capacities despite sharing the same displacement and cylinder configuration. The 169 kW version lists 2.6 liters as a fixed refill, whereas the 187 kW version lists a range of 3.5 to 4 liters, pointing to a difference in transmission hardware or fluid circuit volume between the two power outputs.
