Additional Notes

  • The Audi R8 42 (USA) hydraulic brake system holds a capacity of 1 liter across all listed configurations, spanning both the 4.2 FSI and 5.2 FSI engine variants from 2007-2015. A 1-liter figure is consistent with a service fill quantity for a passenger car brake circuit rather than a full system overhaul volume.
  • Every configuration carries a first check only interval set at 5,000 miles or 12 months, whichever comes first. A first check only designation means the inspection applies solely to the initial service event and does not recur on the same schedule thereafter.
  • Under normal use conditions, the brake fluid check interval is 10,000 miles or 12 months, with a fluid change required every 24 months. The time-based change interval reflects the hygroscopic nature of brake fluid, which absorbs moisture over time regardless of mileage, lowering the boiling point of the fluid in the hydraulic brake system.
  • The 4.2 FSI quattro engine appeared in two distinct output ratings across the 2007-2015 span: 309 kW for the 2007-2010 period and 316 kW for the 2010-2015 period. Despite the difference in power output, both share identical brake fluid capacity and service interval specifications.
  • The 5.2 FSI quattro engine was listed in three separate output ratings: 386 kW, 412 kW, and 404 kW. The 386 kW variant spans the widest production window, appearing across three separate configuration entries covering 2008-2015, while the 412 kW variant covers 2011-2013 and the 404 kW plus variant covers 2013-2015.
  • The R8 5.2 FSI plus quattro at 404 kW, introduced in the 2013-2015 configuration, carries the same 1-liter brake fluid capacity and the same 10,000-mile or 12-month check interval under normal use as all other listed variants, with the 24-month change interval also unchanged.
  • The overlap year of 2010 appears in both the 309 kW and 316 kW 4.2 FSI configurations, as well as in both the 2008-2010 and 2010-2012 entries for the 386 kW 5.2 FSI variant. This reflects mid-cycle specification transitions where two configuration entries share a boundary model year.
