Additional Notes

  • The hydraulic brake system capacity across all A4 Allroad configurations in the 2012-2016 range is listed at 1 liter, a figure consistent with a service fill rather than a full system overhaul, which would typically require bleeding and account for reservoir plus line volume.
  • The Audi A4 Allroad 8KH and 8K variants share an identical normal-use check interval of 10,000 miles or 12 months, whichever comes first, alongside a fixed change interval of 24 months regardless of mileage.
  • The 24-month change interval for brake fluid reflects the hygroscopic nature of glycol-based brake fluids, which absorb moisture over time and lower the boiling point of the fluid, making time-based replacement standard practice independent of distance driven.
  • A separate first-check-only condition is specified for both the 155 kW (8KH, 2012-2013) and 162 kW (8K, 2013-2016) variants, placing an earlier inspection at 5,000 miles or 12 months, applied solely to the initial service interval rather than recurring maintenance.
  • The 155 kW output identifies the 2012-2013 A4 Allroad 8KH as a distinct engine variant from the 162 kW unit found in the 2013-2016 8K, yet both share identical brake fluid capacity and interval figures across all use conditions listed in the specifications.
  • The overlap year of 2013 appears in both the 8KH (2012-2013) and 8K (2013-2016) entries, indicating that two separate powertrain configurations carrying different output ratings were present within the same model year.
