Additional Notes
- Both the Q5 Sportback 45 TFSI quattro ultra (185 kW) and the SQ5 Sportback 3.0 TFSI quattro (260 kW) share a brake fluid capacity of 1 liter, which is a typical reservoir fill volume for passenger vehicle brake systems rather than a full hydraulic circuit overhaul figure.
- The 1-liter capacity reflects the amount of fluid held in the master cylinder reservoir, the point from which fluid level is monitored and topped off during routine service.
- A check interval of 10,000 miles or 12 months, whichever comes first, applies to both configurations under normal use conditions, meaning the fluid level and condition are assessed at each of those service visits.
- The change interval of 24 months is independent of mileage for both configurations, meaning elapsed time alone triggers a fluid replacement regardless of how many miles have accumulated.
- Brake fluid absorbs moisture over time through a process called hygroscopic absorption, which lowers the fluid's boiling point and reduces braking effectiveness, making a time-based change interval the standard approach across both the 185 kW and 260 kW variants.
- Despite the significant power difference between the 45 TFSI quattro ultra at 185 kW and the SQ5 Sportback 3.0 TFSI at 260 kW, both share identical brake fluid service specifications, including capacity, check frequency, and change interval.
