1.6 ADBLUE
AdBlue is a non-inflammable, non-poisonous, colourless,
odourless and water soluble liquid. AdBlue is a liquid that
consists of 32.5% urea and 67.5% water. Special additives
are not permitted. If AdBlue comes into contact with painted
or aluminium surfaces when refuelling, rinse the area con-
cerned immediately with plenty of water.
High temperatures
If AdBlue is heated in the tank to a temperature of 50 °C for
a long period of time, ammonia fumes may be released from
the AdBlue as a waste product. Ammonia fumes have a pen-
etrating smell. Therefore, avoid inhaling ammonia fumes that
may escape when unscrewing the AdBlue tank’s filler cap.
This concentration of ammonia fumes is not poisonous or
harmful to your health.
Low temperatures
AdBlue freezes at a temperature of approx. -11° C.
Measuring the urea concentration in AdBlue
The urea concentration in AdBlue can be measured using a
refractometer.
Use a soft, lint-free cloth to clean the prism and the flip lid and
apply a few drops of the liquid to be measured on the prism
(1). Closing the lid (2) will cause the liquid to be evenly dis-
tributed. Aim the refractometer at a light or a bright back-
ground so that the scale and the separation between light
and dark can be seen more easily. Rotate the eye piece (3)
so that the scale is clearly visible. The measured value for
the sample can be read on the border between light and
dark.
DIN V70070 refractometer scale for a 32.5% urea solution.
At 20 °C, the permitted deviation is between 31.8% and
33.3%.
Special additives
Do not use any special additives for AdBlue and do not use
tap water to dilute AdBlue. This can irreparably damage the
exhaust gas after-treatment system. Liability for material
errors is no longer valid in the event of damage as a result of
the use of such additives or tap water.
Storage instructions
• Only use original storage tanks.
• Store in a cool, dry, ventilated area.
• Protect storage tanks against freezing.
• Observe the manufacturer’s storage and usage instruc-
tions.
AdBlue must meet the DIN 70070
specifications.
