Additional Notes
- All three configurations in the Audi A5, S5, RS 5 Sportback F5A / F5F lineup share a brake fluid capacity of 1 liter, which reflects a service fill volume for the hydraulic brake circuit rather than a full system overhaul quantity.
- The RS 5 Sportback 2.9 TFSI quattro (331 kW) specification identifies the system explicitly as a hydraulic brake system, while the A5 Sportback 40 TFSI quattro (150 kW) and A5 Sportback 45 TFSI quattro (195 kW) entries reference it simply as the brake system.
- Across all three configurations, the brake fluid change interval is set at 24 months under normal use conditions, meaning time elapsed is the governing factor rather than mileage accumulation.
- The check interval for all three configurations is 10,000 miles or 12 months under normal use, whichever comes first, placing fluid inspection on a more frequent cycle than the fluid change itself.
