Audi Q7, SQ7, 4MB / 4MG (USA)

Additional Notes

• The front differential dry fill capacity across all Q7 and SQ7 configurations listed is 1 liter. Dry fill refers to the total fluid volume required when a differential housing is completely empty, such as after a full rebuild or replacement, rather than a routine top-up or fluid exchange.
• Front differential refill capacity differs between configurations. The Q7 2.0 T quattro (185 kW) and Q7 3.0 T quattro (245 kW) for 2016-2018, along with the Q7 45 TFSI quattro variants and the Q7 55 TFSI quattro (245 kW) for 2018-2019, all share a 0.8 liter refill figure. The Q7 55 TFSI quattro (250 kW) from 2019 and the Audi SQ7 4.0 TFSI quattro (373 kW) from 2019 both specify a slightly higher 0.9 liter refill capacity for the front differential.
• The rear differential initial fill capacity for most Q7 configurations is 0.85 liter. An initial fill value represents the amount of fluid needed when filling a unit that has been drained or is new, and the 0.85 liter figure applies consistently across the Q7 2.0 T quattro, Q7 3.0 T quattro, and all Q7 45 TFSI and 55 TFSI variants in the specifications.
• The SQ7 4.0 TFSI quattro (373 kW) rear differential specifications include a notably larger initial fill capacity of 1.5 liters for one rear differential section, compared to the 0.85 liter figure seen across Q7 variants. A separate outer sections entry for the same SQ7 rear differential lists a 1.2 liter initial fill, indicating a multi-section rear differential assembly with distinct fluid compartments.
• The SQ7 4.0 TFSI quattro (373 kW) is the only configuration in the specifications that carries a defined fluid change interval. Both the rear differential and the rear differential outer sections entries specify a change at 60,000 miles under normal use conditions. No equivalent change interval appears in any Q7 variant listed.
• All configurations across the full 2016-2022 range share a uniform fluid check interval of 20,000 miles or 24 months, whichever comes first, under normal use conditions. Both the mileage and time thresholds apply together, meaning the earlier of the two triggers the check.
• The Q7 45 TFSI quattro (185 kW) spans three separate year groupings in the specifications: 2018-2020, 2020-2022, and a 195 kW variant from 2022. The 185 kW and 195 kW versions share identical front and rear differential capacities and check intervals, with the output increase being the only distinguishing factor between those two entries.
• The Q7 55 TFSI quattro appears in two distinct power outputs across the specifications. The 245 kW version covers 2018-2019 and carries a 0.8 liter front differential refill figure, while the 250 kW version from 2019 onward lists a 0.9 liter front differential refill. Rear differential capacity remains at 0.85 liter for both output levels.
