Diesel Particle Filter - Vauxhall ASTRA Owner's Manual

Diesel particle filter

3
The diesel particle filter system removes
polluting soot particles out of the engine
exhaust gases. The system includes a
self-cleaning function that operates
automatically while driving. The filter is
cleaned by burning the trapped soot
particles at a high temperature. There may
be an increase in fuel consumption,
exhaust smell, and engine cooling fan
operation 3 during the self-cleaning
operation.
The self-cleaning function cannot operate
automatically during certain driving
situations where the engine does not reach
its normal operating temperature. An
example of this would be short distance
driving in cold weather.
If the filter needs cleaning and recent
driving situations did not allow the function
to automatically operate, then the control
indicator ! will flash. If this occurs, then
you may continue to drive the vehicle
normally. The vehicle will not be damaged
and does not require service.
The self-cleaning function will
automatically operate while driving after
the engine has reached its normal
operating temperature. The control
indicator ! will continue to flash until the
self-cleaning operation is complete. This
may take up to 20 minutes of driving. The
time will be shorter at higher vehicle
speeds.
