Additional Notes

  • The Audi A4 Allroad 8K / 8KH (USA) carries a 1-liter differential fluid capacity across both the front differential (sourced from the automatic transmission) and the rear differential, applying equally to the 155 kW variant from 2012-2013 and the 162 kW variant from 2013-2016.
  • A 1-liter capacity for a differential is a relatively modest fill volume, consistent with compact rear and front differential housings typical of all-wheel-drive passenger cars rather than larger truck-based units.
  • Under normal use conditions, the differential fluid check interval is set at 20,000 miles or 24 months, whichever comes first, for both the front and rear differentials across all configurations in the 2012-2016 range.
  • A first-check-only interval of 15,000 miles or 24 months applies to both the front and rear differentials, meaning the initial inspection after a fluid fill or service occurs earlier than subsequent normal-use checks.
  • The 5,000-mile difference between the first-check-only interval (15,000 miles) and the normal interval (20,000 miles) reflects a break-in verification practice, where newly serviced differentials are inspected sooner to confirm fluid condition before returning to the standard cadence.
  • The front differential fluid specification is noted as sourced from the automatic transmission, indicating the front differential shares its fluid supply or housing with the automatic gearbox rather than operating as a fully independent unit.
  • Both the 155 kW (8KH) and 162 kW (8K) engine variants share identical differential fluid capacities and check intervals, meaning the power output difference between the two configurations does not affect differential service specifications.
