Additional Notes

  • The Audi A4 Allroad 8WH/8WJ cooling system capacity is 10 liters across all listed configurations, which represents a full system fill volume including the engine block, radiator, and reservoir.
  • The 2.0 TFSI quattro (185 kW) variant covering 2016-2018 carries the same 10-liter cooling system capacity as the later 45 TFSI quattro variants, indicating no volumetric change between those generations.
  • The coolant check interval for all listed configurations is set at 20,000 miles or 24 months under normal use conditions, whichever comes first.
  • The 45 TFSI quattro (185 kW) spanning 2018-2020 and the 45 TFSI quattro (195 kW) starting from 2020 share identical cooling system capacity and check interval specifications despite the difference in power output between the two.
  • A 24-month time-based interval running alongside the 20,000-mile mileage interval means the coolant condition is subject to review based on elapsed time even when mileage accumulation is low, as is common in vehicles driven infrequently.
