Additional Notes

  • Across all Audi Q5 and SQ5 FY/FYG configurations covered, the cooling system capacity is uniformly 10 liters. A figure at this level is typical of a full cooling system fill, accounting for the radiator, engine block passages, heater core circuit, and expansion reservoir combined.
  • The Audi Q5 2.0 TFSI quattro ultra at 185 kW, covering model years 2017-2018, shares the same 10-liter cooling system capacity as later and higher-output variants, indicating no meaningful change in cooling circuit volume across the generation's engine lineup.
  • The Q5 45 TFSI quattro ultra appears in two distinct power outputs: 185 kW for 2018-2021 and 195 kW from 2021 onward. Despite the output difference, both share the identical 10-liter capacity and the same 20,000-mile or 24-month check interval.
  • The Q5 55 TFSI e quattro at 270 kW is a plug-in hybrid configuration. Even with the added thermal management demands of a hybrid powertrain, the specified cooling system capacity remains at 10 liters, consistent with all other variants in the lineup.
  • The SQ5 3.0 TFSI quattro at 260 kW is listed under two separate entries: one covering 2017-2018 and another starting from 2018. Both carry the same 10-liter capacity and 20,000-mile or 24-month check interval, with no specification difference between the two entries.
  • The check interval of 20,000 miles or 24 months applies under normal use conditions across every configuration listed. In coolant service contexts, a check interval is distinct from a full drain-and-fill interval, referring specifically to inspecting concentration, level, and condition rather than replacing the fluid.
  • The dual-format interval of 20,000 miles or 24 months means whichever threshold arrives first triggers the check. For lower-mileage vehicles, the 24-month time limit would typically govern, while higher-mileage use would reach the distance threshold sooner.
