Additional Notes

  • Across all listed configurations of the Audi A5, S5, and RS 5 in the F5/F53/F5P generation for the USA market, the cooling system capacity is uniformly specified at 10 liters. A 10-liter figure represents a full system fill, accounting for the radiator, engine block passages, heater core, and expansion tank combined.
  • The 10-liter cooling system capacity applies equally to the four-cylinder 2.0 TFSI variants and the six-cylinder engines found in the S5 Coupé 3.0 TFSI and RS 5 Coupé 2.9 TFSI, indicating no variation in total coolant volume across displacement levels within this generation.
  • The RS 5 Coupé 2.9 TFSI quattro at 331 kW carries the same 10-liter cooling system capacity as the lower-output A5 variants. The 2.9 TFSI is a twin-turbocharged V6, which typically involves a more complex cooling circuit, yet the total specified fill volume remains consistent with the rest of the lineup.
  • The A5 45 TFSI quattro appears in two distinct output ratings across the 2018-2020 period: 185 kW and 195 kW. Both share the same 10-liter cooling system capacity and the same 20,000-mile or 24-month check interval under normal use conditions.
  • The coolant check interval across all listed configurations is set at 20,000 miles or 24 months under normal use conditions. A time-based interval running alongside a mileage-based one means whichever threshold is reached first triggers the service, which is standard practice for vehicles that may accumulate low annual mileage.
  • The A5 40 TFSI quattro ultra at 150 kW, introduced from 2020 onward, shares the same 10-liter capacity and 20,000-mile/24-month check interval as the higher-output A5 45 TFSI quattro variants, despite the difference in power output between the two four-cylinder configurations.
  • The S5 Coupé 3.0 TFSI quattro at 260 kW is listed across two separate entries covering 2017-2018 and from 2018 onward. Both entries carry identical specifications of 10 liters capacity and a 20,000-mile or 24-month check interval under normal use conditions.
