Additional Notes

  • The Audi A4 Allroad (8WH/8WJ) rear differential specifications list two distinct capacity values across all configurations: 0.96 liter and 0.67 liter. In rear differential servicing, the presence of two separate capacity figures for the same unit typically reflects a dry fill (overhaul) volume versus a service fill (partial drain and refill) volume, with the larger figure representing the full overhaul capacity.
  • The 0.96-liter figure appears consistently across the 2.0 TFSI quattro (185 kW) for 2016-2018, the 45 TFSI quattro (185 kW) for 2018-2020, and the 45 TFSI quattro (195 kW) from 2020 onward, indicating no variation in the full rear differential capacity across any of the listed model year ranges or power outputs.
  • The 0.67-liter figure similarly remains unchanged across all three configurations and their respective year ranges, reinforcing that the service fill volume for the rear differential is consistent regardless of the engine output variant.
  • All six specification rows carry a normal use condition, meaning the 20,000-mile or 24-month check interval applies specifically to standard operating conditions rather than a more demanding use cycle.
  • The check interval of 20,000 miles or 24 months is structured as a dual trigger, where whichever threshold is reached first would govern the service timing. A 24-month ceiling means that even low-mileage operation does not extend the interval beyond two years.
  • The transition from the 2.0 TFSI quattro (185 kW) designation to the 45 TFSI quattro (185 kW) designation at the 2018 model year reflects Audi's shift to a power-based naming convention, though the rear differential capacity and check interval specifications remain identical between the two designations at the same output level.
  • The 45 TFSI quattro (195 kW) variant, introduced from 2020, represents a 10 kW increase over the preceding 185 kW configurations, yet the rear differential fluid capacities of 0.96 liter and 0.67 liter and the 20,000-mile or 24-month check interval are unchanged from the earlier variants.
