Additional Notes
- Across all listed Audi A5, S5, and RS 5 Sportback configurations spanning the 2.0 TFSI, 2.9 TFSI, and 3.0 TFSI engine families, the cooling system capacity is uniformly 10 liters. A 10-liter figure represents a full system fill, accounting for the radiator, engine block passages, heater core, and expansion reservoir combined.
- The 10-liter capacity remains consistent regardless of output differences between configurations, from the A5 Sportback 40 TFSI quattro at 150 kW to the RS 5 Sportback 2.9 TFSI quattro at 331 kW.
- All listed configurations carry a normal use condition, meaning the 20,000-mile or 24-month check interval applies to standard operating environments rather than severe-duty cycles such as extended idling, towing, or extreme temperature exposure.
- The check interval of 20,000 miles or 24 months is a condition inspection interval, not a full coolant replacement interval. Coolant checks at this frequency typically involve verifying concentration, pH level, and visual condition rather than draining and refilling the system.
- The A5 Sportback 2.0 TFSI quattro at 185 kW covers 2017-2018, while the A5 Sportback 45 TFSI quattro carries the same 185 kW output for 2018-2020. Both share the 10-liter capacity and identical check interval, despite the nomenclature change between model year cycles.
- The A5 Sportback 45 TFSI quattro was later revised to 195 kW from 2020 onward. The cooling system capacity and check interval remain unchanged at 10 liters and 20,000 miles or 24 months relative to the earlier 185 kW variant of the same designation.
- The S5 Sportback 3.0 TFSI quattro at 260 kW appears across two separate row entries, one covering 2017-2018 and another starting from 2018. Both entries share identical cooling system specifications, with 10 liters capacity and a 20,000-mile or 24-month check interval under normal use conditions.
