That light is important.
Your diesel particulate filter light or DPF light may come on for a number of reasons. It is a light that should be not be ignored. Ignoring this light can cause more series issues with your emissions and exhaust system.
The light typically comes on when it's time for a regen. Many times your system will do an automatic regen while you are driving. If it has an error then the regen may need to be done manually or forced.
A regen is the self cleaning process that burns off the soot that has accumulated in the diesel particulate filter. It does this by raising the temperate of the exhaust to 1000 to 1200 degrees approximately. This temperature burns out the soot that has accumulated and allows your system to function properly.
If your light has come on and your system will not do a regen then it could be from a number of reasons. Your DPF could have excess soot, it has had to many short trips and low speed driving that has not allowed a regen to happen, excessive idling can cause soot to build up quickly and interrupted regens where you turn off the engine mid regen.
If you've got a DPF light on give us a call and let us take care of you.
