Valtra (Valmet) A4 series

AdBlue (DEF) capacity & service interval

Valtra (Valmet) A4 series vehicles use AdBlue (DEF) with a capacity range of 15 to 20 liters. The data covers 5 configurations.

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

Additional Notes

  • The Valtra (Valmet) A4 series uses a selective catalytic reduction (SCR) system, which injects AdBlue (DEF) into the exhaust stream to reduce nitrogen oxide emissions in compliance with emissions regulations.
  • Across the A4 series lineup from 2018-2020, AdBlue tank capacity falls into one of two values: 15 liters or 20 liters, depending on the specific model variant.
  • The A74, A84, and A94 models from 2018-2020 share an identical AdBlue tank capacity of 15 liters, indicating a common SCR reservoir specification across those three variants.
  • The A104 and A114 models from 2018-2020 are fitted with a larger 20-liter AdBlue tank, a capacity increase of 5 liters over the lower variants in the same series.
  • A 20-liter AdBlue capacity on the A104 and A114 means the reservoir can hold a meaningfully larger volume of reductant fluid, which generally corresponds to longer intervals between refills during normal operation.
  • All five A4 series variants carry their AdBlue capacity specifications under normal use conditions, meaning the 15-liter and 20-liter figures apply to standard operating environments rather than severe-duty cycles.
