Audi Quattro (EU)

Differential fluid capacity & service interval

Audi Quattro (EU) uses differential fluid with a capacity of 2,2 liters. Service intervals occur every 15000 km or 12 months. The data covers 3 configurations.

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

Additional Notes

  • The rear differential capacity across all three configurations — the Quattro (147 kW), the Quattro (162 kW), and the Sport quattro — is 2.2 liters, a figure that represents a service fill level rather than a full overhaul or dry-fill volume.
  • A 2.2-liter rear differential fill is a moderately sized capacity for a performance-oriented all-wheel-drive system, consistent with a dedicated rear differential housing rather than a combined transaxle unit.
  • The Audi Quattro (EU) rear differential carries a check interval of 15,000 km or 12 months under normal use conditions, whichever comes first.
  • The 15,000 km or 12-month check interval applies specifically to normal use conditions across all three listed configurations, meaning the interval is tied to routine driving rather than demanding or high-stress operation.
  • The 147 kW variant covers model years 1980-1989, while the 162 kW variant covers 1989-1991, meaning 1989 represents a year in which both power outputs were in production simultaneously.
  • Despite the difference in power output between the 147 kW and 162 kW variants, the rear differential capacity and check interval remain identical at 2.2 liters and 15,000 km or 12 months respectively.
  • The Sport quattro, produced from 1983-1987, shares the same 2.2-liter rear differential capacity and 15,000 km or 12-month check interval as the standard Quattro variants, despite being a significantly shorter-wheelbase, homologation-derived model.
