Additional Notes

  • The Audi A5 2.0 TFSI quattro (155 kW) and A5 3.2 FSI quattro (195 kW) share an identical transaxle and transferbox combined fluid capacity of 4.8 liters, which is notably higher than the 3.8-liter figure specified for S5 variants across all listed configurations.
  • A capacity labeled as "Initial fill" reflects the volume used when fluid is introduced into a dry or newly assembled unit, as opposed to a service refill following a partial drain. The 4.8-liter initial fill applies to the A5 2.0 TFSI quattro (155 kW) for 2008-2013, and the same designation appears on the S5 4.2 FSI quattro (260 kW) at 3.8 liters.
  • A "first check only" interval is a one-time early inspection performed shortly after a new or freshly serviced unit enters service, intended to catch any early fluid contamination or level irregularities before the standard recurring schedule takes over. For the A5 2.0 TFSI quattro (155 kW), the first check only interval is set at 15,000 miles or 12 months, compared to the normal recurring interval of 20,000 miles or 12 months.
  • The A5 3.2 FSI quattro (195 kW) appears in two separate year range entries, 2007-2009 and 2009-2010, both carrying identical capacity and interval specifications of 4.8 liters with a normal check at 20,000 miles or 12 months and a first check only at 15,000 miles or 12 months.
  • The S5 4.2 FSI quattro (260 kW) similarly spans two consecutive entries covering 2007-2009 and 2009-2012, both specifying a 3.8-liter initial fill capacity with a normal interval of 20,000 miles or 12 months and a first check only interval of 15,000 miles or 12 months.
  • The S5 3.0 TFSI quattro (245 kW) carries a notably longer time-based interval than other listed configurations. Where most entries specify a 12-month time limit alongside the 20,000-mile distance trigger, the S5 3.0 TFSI quattro (245 kW) for both 2012-2013 and 2013-2017 specifies 24 months, doubling the calendar-based check frequency.
  • No first check only interval is listed for the S5 3.0 TFSI quattro (245 kW) in either the 2012-2013 or 2013-2017 entries, in contrast to the S5 4.2 FSI quattro (260 kW) and both A5 variants, which each carry a dedicated early-inspection interval alongside the normal schedule.
  • The S5 3.0 TFSI quattro (245 kW) and S5 4.2 FSI quattro (260 kW) share the same 3.8-liter capacity figure, despite differing in engine displacement, power output, and service interval structure, indicating the transaxle and transferbox assembly volume remained consistent across those two S5 powertrains.
