Additional Notes

  • The Audi A4 Allroad 8K / 8KH (USA) transfer case holds 1 liter of fluid across all listed configurations, spanning both the 155 kW and 162 kW variants of the 2.0 TFSI engine.
  • A 1-liter transfer case capacity is a relatively small fill volume, consistent with compact, single-speed transfer units commonly found in transverse all-wheel-drive platforms rather than larger, gear-driven units used in body-on-frame vehicles.
  • The 155 kW 2.0 TFSI in the 8KH body (2012-2013) carries a normal-use transfer case check interval of 20,000 miles or 24 months, whichever comes first.
  • For the same 155 kW 8KH configuration, a shortened first-check-only interval of 15,000 miles or 24 months applies, meaning the initial inspection occurs earlier than all subsequent ones.
  • The 162 kW 2.0 TFSI in the 8K body (2013-2016) shares the same normal-use check interval of 20,000 miles or 24 months as the earlier 155 kW variant.
  • The 162 kW 8K configuration also carries a first-check-only interval of 15,000 miles or 24 months, identical in structure to the one specified for the 155 kW 8KH model.
  • The first-check-only interval, set at 15,000 miles, is 5,000 miles shorter than the recurring 20,000-mile normal-use interval, reflecting a common practice of inspecting a newly filled or recently serviced unit before committing to the standard schedule.
  • Both the 24-month time limit on the normal-use interval and the 24-month limit on the first-check-only interval are identical, meaning the calendar-based trigger does not differ between the two conditions despite the mileage difference.
