Audi 100, F104 (EU)

Differential fluid capacity & service interval

Audi 100, F104 (EU) differential fluid capacity is 1,4 liter. Service intervals include checking at 10000 km and changing at 30000 km. The data covers 3 configurations.

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

Additional Notes

  • All three configurations listed for the Audi 100, F104 (EU) share an identical differential fluid capacity of 1.4 liters, applying specifically to differentials sourced from automatic transmissions.
  • A 1.4-liter capacity in a differential context represents a relatively modest fill volume, consistent with the compact final drive units commonly paired with front-wheel-drive automatic transmissions of that era.
  • The check interval across all listed configurations is set at 10,000 km under normal use conditions, meaning routine inspections of the differential fluid level are expected at that mileage threshold.
  • The change interval is specified at 30,000 km under normal use conditions, placing a full fluid replacement every three check cycles for all three configurations.
  • The 100 Coupé S covers model years 1971-1976, the 100 GL covers 1970-1976, and the 100 LS (74 kW) covers 1968-1971, with the LS representing the earliest production window among the listed variants.
  • The 100 LS (74 kW) designation distinguishes a specific power output variant within the LS trim, yet I note the differential fluid capacity and service intervals remain identical to the later Coupé S and GL configurations.
