Additional Notes

  • Across all listed configurations of the Audi 80/82 (B1), the differential fluid capacity from automatic transmission is uniformly 1 liter, indicating a compact final drive unit consistent with the small-displacement engines fitted to the B1 platform.
  • The 1-liter capacity figure represents a service fill volume, meaning the amount used during a routine fluid change rather than a full overhaul or initial factory fill.
  • A fluid level check interval of 15,000 km applies to every listed configuration regardless of use condition, engine output, or model year range.
  • Under normal use conditions, the differential fluid change interval is 45,000 km across all listed engine variants and model year ranges.
  • Under severe use conditions, the change interval shortens to 30,000 km, which represents a 33 percent reduction compared to the normal use interval of 45,000 km.
  • The 1972-1976 80 1.5 (55 kW) and the 1972-1976 80 1.5 (63 kW) share identical capacity and interval specifications, meaning the difference in power output between the two variants had no bearing on differential fluid service requirements.
  • The 1976-1978 model year range introduces the 82 designation alongside the 80, and both the 80 1.5 (55 kW)/82 and the 80 1.6 (63 kW)/82 configurations carry the same 1-liter capacity and the same 15,000 km check and 45,000/30,000 km change intervals as the earlier 1972-1976 variants.
  • The displacement increase from 1.5 to 1.6 liters in the 63 kW variant between the 1972-1976 and 1976-1978 periods produced no change in differential fluid capacity or service intervals.
