Additional Notes

  • The brake fluid reservoir capacity for the Audi 80 quattro 2.1 (1982-1985) is 0.6 liter, which is a typical figure for a passenger car hydraulic brake system reservoir fill rather than a full system overhaul volume.
  • Under normal use conditions, the specified check interval is every 7,500 km or every 6 months, whichever comes first, reflecting the dual-trigger structure common to brake fluid maintenance schedules where both distance and time are monitored independently.
  • The change interval is set at 24 months regardless of distance, which aligns with the hygroscopic nature of brake fluid — a property that causes moisture absorption over time and reduces the fluid's boiling point even when mileage remains low.
