Audi A3, S3, RS 3, 8Y (EU)

Additional Notes

• The Audi A3 8Y (EU) manual transaxle fluid capacity is listed at either 1.7 liters or 2.4 liters depending on the engine variant, meaning the physical gearbox unit differs between configurations rather than sharing a common housing across the lineup.
• The A3 30 TFSI (81 kW) stands out with a 2.4-liter transaxle capacity, which is notably higher than the 1.7-liter figure shared by the other four variants listed, indicating a larger or differently designed manual gearbox assembly for that particular engine pairing.
• The 1.7-liter capacity recorded for the A3 30 TDI (85 kW), A3 35 TDI (110 kW), and A3 35 TFSI (110 kW) reflects a service fill level, meaning the amount of fluid required when refilling during a routine service rather than a full drain-and-rebuild overhaul figure.
• All five configurations carry a normal use condition designation, meaning the listed capacities apply to standard operating conditions rather than a severe-duty or first-change-only service scenario.
• The A3 30 TFSI (85 kW) introduced from 2024 onward shares the 1.7-liter transaxle capacity with the diesel and higher-output petrol variants, rather than matching the 2.4-liter figure of the earlier 81 kW petrol variant despite both being 30 TFSI designations.
• The diesel variants, the 30 TDI (85 kW) and 35 TDI (110 kW), both specify 1.7 liters for their manual transaxles under normal use, indicating a shared gearbox unit across those two diesel output levels within the A3 8Y range.
