Audi Q5, SQ5, FY / FYG (USA)

Additional Notes

• The semi-automatic transmission in the Audi Q5 FY is treated as two separate fluid circuits: a clutch part and a transmission part. Each carries its own capacity figure and, in the case of the clutch part, its own drain-and-fill interval.
• An initial fill of 4.35 liters applies to the clutch part across the Q5 2.0 TFSI quattro ultra (185 kW), Q5 40 TFSI quattro (150 kW), Q5 45 TFSI quattro ultra (185 kW), and Q5 45 TFSI quattro ultra (195 kW). The refill capacity of 3.5 liters for the same clutch part reflects the volume retained in the circuit after a drain, which is always lower than the factory-fill figure used during assembly or overhaul.
• The transmission part of the semi-automatic unit carries a 3.8-liter initial fill across all four TFSI quattro variants listed. No refill capacity is specified for the transmission part, and no fluid change interval is listed for it — only a check interval of every 20,000 miles or 24 months applies.
• The clutch part fluid change interval is set at 40,000 miles for all four TFSI quattro ultra and TFSI quattro configurations. The accompanying check interval of 20,000 miles or 24 months means the fluid condition is assessed at the halfway point before each scheduled change.
• The SQ5 3.0 TFSI quattro (260 kW) uses a conventional automatic transmission rather than the semi-automatic unit found in the Q5 TFSI variants. The fluid system is a single circuit rather than a split clutch-and-transmission arrangement.
• The SQ5 3.0 TFSI quattro initial fill of 8.6 liters is substantially higher than the Q5 semi-automatic clutch and transmission part figures combined. A large initial fill in a conventional automatic transmission typically accounts for fluid held in the torque converter, valve body, and cooler lines in addition to the sump.
• The SQ5 refill capacity is listed as a range of 3.6 to 4.0 liters rather than a fixed value. A variable refill range in an automatic transmission is common when the exact amount of fluid retained after draining depends on whether the torque converter is also drained or only the pan is dropped.
• The SQ5 3.0 TFSI quattro (260 kW) specifications cover two separate production entries: one for 2017-2018 and one starting from 2018. Both entries carry identical capacity and check interval figures.
• No fluid change interval is listed for the SQ5 automatic transmission, only the 20,000-mile or 24-month check interval. In contrast, the Q5 semi-automatic clutch part carries an explicit 40,000-mile change interval under normal use conditions.
• All configurations across the Q5 and SQ5 entries are specified under normal use conditions. The check interval of 20,000 miles or 24 months applies uniformly to every listed variant regardless of transmission type.
