Diesel Particulate Filter clogged
If the dedicated message is displayed, re-
fer to section “Warning lights and mes-
sages”.
During normal service the
catalyst and the diesel par-
ticulate filter (DPF) reach high tem-
peratures. Do not therefore park the
car over inflammable materials (grass,
dry leaves, pine needles, etc.): fire
hazard.
WARNING
PROTECTING THE
ENVIRONMENT
The devices for curtailing petrol engine
emissions are the following:
❒ three-way catalytic converter;
❒Lambda sensors;
❒fuel evaporation system.
In addition, do not let the engine run, even
for a test, with one or more spark plugs
disconnected.
The devices for curtailing diesel fuel en-
gine emissions are the following:
❒oxidising catalytic converter;
❒ exhaust gas recirculation system
(E.G.R.);
❒Lambda sensors;
❒diesel particulate filter (DPF) (where
provided it is fitted instead of the Lamb-
da sensor).DIESEL PARTICULATE FILTER
(DPF) (where provided)
The Diesel Particulate Filter is a mechan-
ical filter, integral with the exhaust system,
that physically traps particulates present
in the exhaust gases of Diesel engines.
The diesel particular filter has been adopt-
ed to eliminate almost totally particulates
in compliance with current / future law
regulations.
During normal use of the car, the engine
control unit records a set of data (e.g.:
travel time, type of route, temperatures,
etc.) and it will then calculate how much
particulates has been trapped by the filter.
Since this filter physically traps particulates,
it shall be cleaned (reclaimed) at regular
intervals by burning carbon particles. Re-
claiming procedure is controlled auto-
matically by the engine control unit ac-
cording to the filter conditions and the
conditions of use of the car. During re-
claiming the following phenomena could
take place: idling slight increase, fan acti-
vation, slight smoke increase, high exhaust
temperatures. These situations shall not
be considered as faults and they do not af-
fect car performance and environment.
