Additional Notes

  • All three engine variants of the Audi 100, 43 (EU) share an identical manual transaxle service fill capacity of 1.6 liters, applying equally to the 1.6, 2.0, and 5E configurations across their respective model year spans.
  • The 1.6-liter capacity figure is classified as a service fill, meaning the quantity reflects a partial drain-and-refill procedure rather than a complete fluid exchange from an empty unit.
  • A service fill value is typically lower than an overhaul or dry fill capacity, as some fluid remains in the transaxle housing and passages during a standard service procedure.
  • The 100 1.6 and 100 2.0 variants share the same 1976-1979 production span, while the 100 5E entered the range one year later, covering 1977-1979, yet all three carry the same 1.6-liter service fill specification.
  • All capacity figures are recorded under normal use conditions, meaning the 1.6-liter service fill applies to standard operating environments without a separate severe-duty interval or capacity listed.
  • The transaxle layout noted across all three rows combines the transmission and final drive into a single integrated unit, which is a relevant factor when interpreting the 1.6-liter figure as it accounts for the shared fluid volume of both functions.
