Additional Notes

  • The Audi Q5 3.2 FSI quattro (199 kW) produced in 2008-2010 carries a transfer case capacity of only 0.5 liter, which is half the 1 liter figure listed for every other configuration in this dataset. The same engine in the 2010-2012 production range lists a full 1 liter capacity, indicating a specification change between those two production periods.
  • The 2012-2013 and 2013-2017 Q5 2.0 TFSI Hybrid quattro configurations are the only ones in this group to distinguish between an initial fill capacity of 1 liter and a refill capacity of 0.8 liters. The lower refill figure reflects that a partial drain during a fluid check or top-up does not empty the housing completely, so less fluid is needed to restore the correct level compared to a dry fill after a full overhaul or unit replacement.
  • All non-hybrid configurations across the 2008-2017 range list a single capacity value of either 0.5 or 1 liter without a separate refill figure, meaning the specification applies uniformly regardless of whether the housing was fully drained or only partially serviced.
  • A "first check only" interval of 15,000 miles appears alongside a standard "normal" interval of 20,000 miles for every configuration listed. The shorter 15,000-mile interval applies exclusively to the initial service event, after which the standard 20,000-mile cadence takes over.
  • Configurations from 2008-2012 pair the 20,000-mile or 15,000-mile distance intervals with a 12-month time limit, while configurations from 2013 onward extend the time component to 24 months. This shift from annual to biennial time-based intervals applies across the 2.0 TFSI, 3.0 TDI, 3.0 TFSI, and SQ5 3.0 TFSI variants introduced or continued from 2013.
  • The Q5 2.0 TFSI quattro at 155 kW covers two overlapping production ranges, 2010-2012 and 2012-2013, both with identical 1-liter capacity and 12-month time intervals. The 162 kW variant introduced for 2013-2017 retains the 1-liter capacity but moves to the 24-month time interval seen across all later configurations.
  • The SQ5 3.0 TFSI quattro at 260 kW shares the same 1-liter transfer case capacity and 20,000-mile / 24-month service interval structure as the Q5 3.0 TFSI at 200 kW for the same 2013-2017 production range, despite the significant difference in output between the two engines.
  • All configurations in this group are noted as sourcing the transfer case from an automatic transmission assembly. The Q5 3.0 TDI quattro (176 kW) for 2013-2017 is listed without the "from automatic" qualifier, distinguishing its transfer case notation from the majority of entries.
