Additional Notes

  • Across all front-wheel-drive configurations in the Audi A4 B5 (USA), the manual transmission fluid capacity is 2.25 liters. This figure represents a service fill volume, meaning the amount required when draining and refilling the transmission during routine maintenance rather than a full overhaul with complete disassembly.
  • All quattro variants carrying a manual transmission are specified at 2.75 liters, which is 0.5 liters more than the front-wheel-drive equivalent. The additional volume accounts for the transfer box integrated into the drivetrain, as the specification note explicitly covers both the transmission and transferbox as a combined system.
  • The S4 2.7 Bi-turbo V6 quattro (187 kW), produced from 1999-2001, carries a distinct 2.3-liter capacity for its manual transaxle and transferbox. The use of the term "transaxle" in the specification note, rather than "transmission," reflects a layout where the transmission and differential are housed in a single combined unit.
  • The 1.8 T 5V configurations from 1997-2001 are assigned a check interval of 10,000 miles or 12 months under normal use conditions, whichever comes first. This is a shorter mileage interval than the one applied to the V6 and S4 configurations.
  • All V6 A4 variants, spanning both the 128 kW (1996-1997) and 142 kW (1997-2001) output levels, share a 15,000-mile or 12-month check interval under normal use conditions. The same interval applies regardless of whether the configuration is front-wheel drive or quattro.
  • The A4 2.8 V6 was available in two distinct power outputs across the B5 generation. The 128 kW version covers 1996-1997, while the 142 kW version spans 1997-2001, with both sharing identical fluid capacity and check interval specifications despite the difference in output.
  • The S4 2.7 Bi-turbo V6 quattro shares the 15,000-mile or 12-month check interval with the V6 A4 configurations, applied under normal use conditions. All intervals listed across the entire model range include a time-based component of 12 months, meaning the interval is triggered by whichever threshold is reached first.
