Audi 100, 43 (EU)

Brake fluid capacity & service interval

Audi 100, 43 (EU) models utilize brake fluid with a capacity range between min and max. Service intervals require a change every 24 months. The data covers 3 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

TypeSpecifications
100 5E (1977-1979)
  • Use: Normal
  • Between min and max.
  • Change 24 months
100 1.6 (1976-1979)
  • Use: Normal
  • Between min and max.
  • Change 24 months
100 2.0 (1976-1979)
  • Use: Normal
  • Between min and max.
  • Change 24 months

Additional Notes

  • All three configurations covered by the Audi 100 43 (EU) specifications share an identical brake fluid service interval of 24 months under normal use conditions.
  • Rather than a fixed volume fill, the brake fluid level specification is expressed as a range, requiring the fluid to sit between the minimum and maximum marks on the reservoir.
  • A between-min-and-max fill specification is characteristic of a sealed hydraulic circuit where fluid is topped off or exchanged without a full system overhaul, meaning no discrete capacity figure in liters is assigned.
  • The 100 1.6 and 100 2.0 variants share the same model year span of 1976-1979, while the 100 5E entered the specification range a year later, in 1977, running through 1979.
  • All three engine variants carry the same hydraulic brake system notation, indicating a conventional hydraulic circuit rather than a power-assisted or integrated braking arrangement with separate fluid demands.
  • The 24-month change interval applies uniformly across the 1.6, 2.0, and 5E engine variants under normal use, with no differentiation based on engine displacement or output.
