Additional Notes

  • All capacities listed are designated as initial fill values, meaning the fluid quantity reflects what is added during a factory or service fill rather than a full drain-and-refill overhaul measurement.
  • The Audi A4 2.0 TFSI quattro (155 kW) transaxle combined with the transfer box carries a 4.8-liter initial fill capacity, which is notably higher than the 3.8-liter figure specified for the S4 (245 kW) across all listed years.
  • The 4.8-liter capacity applies equally to both the sedan and Avant (wagon) body styles of the 155 kW quattro variant, covering the 2008-2010 and 2010-2013 production periods without distinction between the two configurations.
  • Under normal use conditions, the check interval for the A4 2.0 TFSI quattro transaxle and transfer box is set at 20,000 miles or 12 months, whichever comes first, across both the 2008-2010 and 2010-2013 model ranges.
  • A separate first-check-only interval of 15,000 miles or 12 months is specified for the A4 2.0 TFSI quattro variants, applying an earlier inspection point during the initial service period compared to the ongoing normal-use schedule.
  • The S4 (245 kW) covering 2009-2013 shares the same interval structure as the A4 quattro variants, with a normal check at 20,000 miles or 12 months and a first-check-only interval at 15,000 miles or 12 months.
  • For the S4 (245 kW) from 2013-2016, the time-based component of the check interval doubles from 12 months to 24 months under both normal and first-check-only conditions, while the mileage thresholds of 20,000 and 15,000 miles respectively remain unchanged.
  • The extended 24-month time interval introduced for the 2013-2016 S4 represents a meaningful departure from the 12-month ceiling applied to all earlier configurations in the dataset, affecting both the standard and first-check service schedules simultaneously.
