The Diesel particulate filter (DPF) is an integral part of the vehicle
exhaust gas emission reduction systems and it removes the soot
from (Particulate matter) the exhaust gas. Unlike a disposable air
filter, the DPF is regenerative filter. Regeneration is triggered
automatically according to the driving conditions which burns of the
accumulated particles/soot. In other words, the active burning by
engine control system and high exhaust gas temperature caused
by
normal/high
driving

burns
and

However, if the vehicle continues to be driven at either of the
following conditions the accumulated soot may not be automatically
removed because of low exhaust gas temperature.
1.
Heavy traffic driving conditions, especially in city
2.
Frequent short trips
3.
Low speed for a long time
When more than a certain amount of soot deposited,
the DPF lamp illuminates.
If the DPF lamp turns ON or Blinking and the message “

appears in Cluster while driving the vehicle, then it indicates
DPF regeneration has not occurred successfully. At this moment,
we suggest DPF regeneration must be done through a specific
methodology.
