Cleaning The Adblue Tank; Diesel Particulate Filter - Volvo FM Handbook

Cleaning the AdBlue tank

It can be necessary to clean out the AdBluetank if it is
advertently filled with diesel or some liquid other than
AdBlue. Rinse out with water, and if this is not
sufficient, use a domestic cleaning liquid. Rinse out
thoroughly with water to ensure that there is no
cleaning liquid residue left as this can damage the
catalytic converter.
1
Place a collection vessel under the AdBluetank
bottom plug
2 Loosen and unscrew the plug a few turns until the
contents start to run from the tank drain hole.
3 Allow it to drain until the tank is empty
4 Flush the tank out with clean water. Make sure
the tank is properly drained before continuing
5 Replace the plug
6 Empty the container in a place where it will not
constitute a risk to the environment

Diesel particulate filter

This vehicle is equipped with a ceramic particulate
filter that requires the use of low-sulphur fuel (less
than 50 ppm = 0.005 % sulphur) The lower the sulphur
content of the fuel, the better the function and life of
the system. I.e. if a fuel with 10 ppm sulphur is
available, it is recommended to use such a fuel in the
first hand. Use of fuel with a higher sulphur content or
mixing in other fuel can destroy the particulate filter in
a short time.
The particulate filter collects soot and ash particles. A
large quantity of particles will cause a higher exhaust
back-pressure, which leads to higher fuel consumption
and unnecessary wear on the engine. To avoid this,
there is a system that removes the soot particles
automatically by combustion. The combustion process

Note!
After emptying the tank, it must be
filled with a minimum of 5 litres of
new AdBlue.
Note!
The fact that the vehicle is fitted
with a particulate filter does not
mean that it can be used in a
different way than a vehicle without
a particulate filter. Breathing the
exhaust gases is still unhealthy, in
other words good ventilation is still
necessary when the vehicle is idling.
A point-extraction exhaust hose shall
be connected to the tail pipe if the
engine must be run indoors.
