Engine Exhaust - Vauxhall Agila Owner's Manual

9-7 Driving and operating

Engine exhaust

Diesel particle filter (DPF) 3
The diesel particle filter removes
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 30 minutes, during which
time fuel consumption may increase.
The smell and the noise that occur
are normal.
Self-cleaning may begin
automatically during idling; engine
speed increases and cooling fan
operates automatically.
The system cannot automatically
clean itself under certain vehicle
conditions, such as driving short
distances.
If control indicator 8 illuminates, you
should continue driving, and as soon
as the road and traffic situation
permits it, increase speed to more
than 50 mph (75 km/h) and diesel
particle filter cleaning will start.
Cleaning is quicker at faster speeds
and under load. The control indicator
extinguishes as soon as cleaning is
complete.
We recommend that you do not turn
the ignition off during cleaning.
If regeneration of the diesel particle
filter is not successful or possible,
control indicator A may illuminate
and the vehicle goes into limp home
mode: interrupt your journey and
seek the assistance of a workshop
immediately.
