Diesel particle filter 3
The diesel particle system filter polluting
soot particles out of the exhaust.
The system contains a self-cleaning
function at certain intervals. The filter is
cleaned by burning the soot particles at
high temperature, This procedure runs
automatically under certain vehicle
conditions and can take up to 25 minutes,
during which time fuel consumption may
increase. The smell and the noise that
occur are normal.
The system cannot automatically clean
itself under certain vehicle conditions such
as driving short distances.
If the control indicator ! flashes, you
should continue driving and as soon as the
road and traffic situation permits it,
increase speed to more than 25 mph
(40 km/h) and diesel particle filter cleaning
will start. Cleaning is quicker at faster
speeds and under load. The engine speed
should not drop below 2000 rpm. The
control indicator goes off as soon as
cleaning is complete.
We recommend that you do not turn the
ignition off during cleaning.

Maintenance
Have all maintenance work carried out at
the intervals specified by Vauxhall. We
recommend that you entrust this work to
your Vauxhall Authorised Repairer, who
has proper equipment and trained
personnel available. Electronic testing
systems permit rapid diagnosis and
remedy of faults. This way you can be
certain that all components of the vehicle's
electrical, injection and ignition systems
operate correctly, that your vehicle has a
low level of pollutant emission and that the
catalytic converter system will have a long
service life.
Catalytic converter, exhaust gases

Checking and adjustment of the
fuel injection and ignition systems is part of
the scope of inspection. For this reason you
should have all maintenance work carried
out at the intervals specified in your Service
