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

Brake fluid capacity & service interval

Audi A3, S3, RS 3, 8Y (EU) models require 1,15 liters of brake fluid. The service interval for fluid replacement is 24 months. The data covers 2 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

TypeSpecifications
S3 2.0 TFSI quattro (245 kW) (2024- )
  • Use: Normal
  • Capacity 1,15 liter
  • Change 24 months
S3 2.0 TFSI quattro (228 kW) (2020-2024)
  • Use: Normal
  • Capacity 1,15 liter
  • Change 24 months

Additional Notes

  • The Audi S3 2.0 TFSI quattro at 228 kW, covering 2020-2024, carries a brake fluid capacity of 1.15 liters for the hydraulic brake system, which is a typical reservoir and line fill volume for a passenger car of this class.
  • The 245 kW variant introduced from 2024 onward shares the same 1.15-liter brake fluid capacity, indicating no change to the hydraulic brake system volume despite the increase in output over the 228 kW version.
  • Both the 228 kW and 245 kW S3 configurations specify a 24-month change interval under normal use conditions, meaning brake fluid replacement is time-based rather than mileage-based in standard driving circumstances.
  • A 24-month brake fluid service interval reflects the hygroscopic nature of brake fluid, which absorbs moisture over time and lowers its boiling point regardless of how many kilometers have been driven.
