Brake fluid capacity & service interval

Audi A5, S5, RS 5, 8T (USA) models require 1 liter of brake fluid. Service intervals include checks at 5000 miles or 12 months and 10000 miles or 12 months, with a fluid change required every 24 months. The data covers 16 configurations.

Additional Notes

  • A 1-liter capacity figure applies uniformly across all listed configurations of the Audi A5, S5, and RS 5 (8T, USA). In brake system servicing, this value represents the total fluid volume held within the reservoir and hydraulic circuit, not a flush quantity, so actual replacement volume during a change interval may be less.
  • Under normal use conditions, every listed configuration calls for a brake fluid check at 10,000 miles or 12 months, whichever comes first. The time-based component of that interval reflects the hygroscopic nature of brake fluid, which absorbs moisture from the atmosphere over time regardless of mileage accumulated.
  • The change interval under normal use conditions is set at 24 months across all listed configurations. A time-based replacement schedule rather than a mileage-based one is standard practice for brake fluid because moisture absorption, not mechanical wear, is the primary degradation mechanism.
  • A separate "first check only" condition appears for all A5 and RS 5 configurations but is absent from both S5 3.0 TFSI quattro entries. Under that condition, the check interval is shortened to 5,000 miles or 12 months, applying only to the initial service inspection after the vehicle enters service.
  • The A5 2.0 TFSI (155 kW) front-wheel-drive variant shares identical brake fluid capacity and interval specifications with the A5 2.0 TFSI quattro (155 kW). The addition of all-wheel drive hardware does not alter the brake system fluid volume or service schedule in these specifications.
  • The A5 2.0 TFSI quattro received a power increase from 155 kW to 162 kW for the 2013-2017 model years. Despite the engine revision, brake fluid capacity and all service intervals remain unchanged between the two output variants.
  • The A5 3.2 FSI quattro (195 kW) appears across two overlapping production ranges, 2007-2009 and 2009-2010, with 2009 common to both. Brake fluid specifications are identical across both ranges, indicating no service-related changes were introduced during that transition period.
  • The RS 5 4.2 FSI quattro (331 kW) is the highest-output configuration listed, rated at 331 kW. Despite the substantially greater power output compared to the A5 variants, the brake fluid capacity of 1 liter and the 24-month change interval under normal use conditions are consistent with all other listed models.
  • The S5 3.0 TFSI quattro (245 kW) entries cover 2012-2013 and 2013-2017 as separate rows, with 2013 appearing in both. Specifications are identical across both rows, and no "first check only" condition is listed for either S5 entry.
