A nd AdB L u E® AddItIVE
AdBlue® is the brand name of the solution
needed for operation of the SCR system.
BlueHDI vehicles have a specific AdBlue
®
additive tank with a capacity of 15 litres.
It has an exterior filler located behind the
fuel filler flap below the fuel filler cap and
closed with a blue filler cap.
The objective of BlueHDi is to reduce by
up to 90% the emissions of NOx (nitrous
oxides) in the air, using a system that
converts NOx into water vapour and nitrogen
in a dedicated catalytic converter: SCR
(Selective Catalytic Reduction).
This objective meets the "Euro 6" emissions
standard adopted by the European Union
aimed at limiting the emissions of pollutants
from internal combustion engines.
The SCR technology used on BlueHDi
engines involves the injection of AdBlue
®
fluid into the exhaust system. This operation can also be carried out
by a CITROËN dealer or a qualified
workshop.
Scr technology
Filling of the AdBlue® tank can be done
using:
-

5 or 10 litres containers equipped with a

10 centimetre filler tube or the filling kit
available from CITROËN dealers,
-

1.89 litre botles that are screwed onto

the filler neck, available from CITROËN
dealers,
-

or when at a fuel filling station equipped

with a special AdBlue
® delivery pump for
heavy or light vehicles.

Check and top up the fluid level regularly. Replace the fluid
annually. Replace the fluid if it contains water.
Check the condition of the hydraulic hose and the sealing of the
hydraulic system regularly.
Pump and motor
Requires no servicing, the ball bearings are lubricated for life and
the plain bearings by the pumped fluid.
Lubrication
The tipper body and ram pivots do not have grease nipples.
Lubricate regularly the hinges and retainers for the tipper body sides
as well as the catches for the rear tipper body side.
Sub-chassis and tipper body
For maximum life, we recommend that you clean your tipper body
by washing it down regularly with hose.
Touch-in the paint chips quickly to avoid the spread of rust.
After 8 months of use, check the tightening torque of the
fixings of the underbody to the chassis (following the
recommendations of the body converter).
