Adblue (Bluehdi Diesel); And Scr System - CITROËN C3 Handbook

and SCR system

®
AdBlue
for BlueHDi Diesel engines
To assure respect for the environment and
conformity with the new Euro 6 emissions
standard, without adversely affecting the
performance or fuel consumption of Diesel
engines, CITROËN has taken the decision to
equip its vehicles with an effective system that
associates SCR (Selective Catalytic Reduction)
with a particle filter (FAP) for the treatment of
exhaust gases.
SCR system
Using a fluid called AdBlue containing urea, a
®
catalytic converter turns up to 85% of nitrogen
oxides (NOx) into nitrogen and water, which are
harmless to health and the environment.
is held in a special tank with

The AdBlue
a capacity of about 15 litres: this provides
a driving range of about 11 000 miles
(18 000 km). An alert is triggered automatically
to warn you when the reserve level is
reached: you can then drive about 1 500 miles
(2 400 km) before the tank is empty.
Practical information
tank is empty, a
®
Once the AdBlue
system required by regulations prevents
starting of the engine.
If the SCR system is faulty, the level
of emissions from your vehicle will no
longer meet the Euro 6 standard: your
vehicle becomes polluting.
In the event of a confirmed fault
with the SCR system, you must go
to a CITROËN dealer or a qualified
workshop as soon as possible: after
a running distance of 650 miles
(1 100 km), a system will be triggered
automatically to prevent engine starting.
In either case, a range indicator gives
you the distance you can travel before
the vehicle is immobilised.
Freezing of the AdBlue ®
freezes at temperatures below
AdBlue ®
around -11°C.
The SCR system includes a heater
tank, allowing you
for the AdBlue ®
to continue driving in all weather
conditions.
