Emission control with AdBlue
AdBlue is an additive used in the SCR
tem to reduce emissions of noxious sub-
stances from a diesel engine.
In the SCR system, the AdBlue and the nitrous
oxide exhaust gas substance are converted to
nitrogen and water vapour, which significantly
reduces the emissions of harmful nitrous
oxides.
AdBlue
AdBlue is a colourless liquid consisting of
26
32.5% urea in deionised water and is manu-
factured in accordance with the ISO 22241
standard. It is specially developed for SCR
cleaning technology for diesel engines.
AdBlue has its own tank in the car which is
topped up via a separate filler pipe behind the
fuel filler flap. Consumption depends on driv-
ing style, outside temperature and the operat-
ing temperature of the system.
Conditions for driving with AdBlue
There must always be AdBlue of the correct
quality in the AdBlue tank before the car can
be started. The SCR system is very sensitive
to contaminants.
The emission control system continuously
monitors the tank level, quality and dosage of

IMPORTANT
AdBlue is required for the function of the
SCR system and legal emissions compli-
ance. It is illegal to modify or manipulate
the AdBlue supply system in any way so
that no AdBlue reagent is consumed when
it is required for legal exhaust emissions
compliance. Any such tampering may be a
criminal offence which may lead to legal
prosecution actions.
It is not permitted to operate the car with
an empty AdBlue tank, since it will no
longer be compliant with the legal require-
ments for exhaust emissions. Therefore,
the car is equipped with a warning system
to inform when AdBlue refilling is required.
When the fill level in the AdBlue tank is
getting low, warnings are displayed to
inform that AdBlue refilling is required.
