Additional Notes

  • The Audi A6 Allroad 4B (USA) manual transaxle fluid capacity is listed as a range of 2.3 to 3.6 liters across all covered configurations, which reflects an initial fill specification rather than a fixed single volume. A range of this width typically accounts for variation in fluid level at the time of service, with the lower value representing a minimum acceptable level and the upper value representing a full fill.
  • The 169 kW Bi Turbo 2.7 5V quattro variant, covering 2002-2005, carries an explicit "Initial fill" label alongside the 2.3-3.6 liter capacity figure, indicating the specification applies to a first-time fluid fill rather than a routine top-up or drain-and-refill service.
  • Under normal use conditions, the manual transaxle check interval for all listed configurations is 20,000 miles or 12 months, whichever comes first. The dual-trigger format means the time-based threshold of 12 months applies even when mileage accumulation is low.
  • A separate "first check only" interval of 15,000 miles or 12 months is specified for all configurations. A first-check interval of this type is typically intended to catch early fluid contamination or level changes that can occur during the break-in period of a new or freshly serviced transmission.
  • The 187 kW Bi Turbo 2.7 5V quattro appears across two distinct year ranges in the specifications: 2000-2002 and 2002-2004. Both ranges share identical capacity figures and check intervals under both normal and first-check-only conditions, meaning no specification difference exists between the two production periods for this output variant.
  • All six specification rows reference a transaxle rather than a standalone gearbox, which is consistent with the quattro all-wheel-drive layout where the transmission and front differential share a common housing, influencing the fluid volume range cited.
