What is a diesel particulate filter?
A diesel particulate filter (DPF) is a filter that captures and stores exhaust soot in order to reduce emissions from diesel cars. But since they only have a finite ability, this trapped soot occasionally has to be emptied or 'burned off' to renew the DPF. This regeneration process cleanly burn off the excess soot deposited in the filter, reducing the harmful exhaust emission and helps to prevent the tell-tale black smoke you used to see from diesel vehicles, particularly when accelerating.
• You include to empty your DPF regularly in order to have best performance.
• In arrange to empty your DPF, you have to burn off the composed soot.
• Soot is burned off at a high temperature by driving at a speed of more than 40 miles per hour for
approximately ten minutes.
• When the soot is being burned off, you may notice that you get a hot smell from your exhaust, your idle speed is higher, and your fuel consumption is greater.
Is It secure to Drive with the DPF Light On?
Yes, you can. Probably. You are not likely going to be harmed. Your engine, however, is another thing. If you disregard the DPF light, and you carry on driving in your usual "gas/brake" outline, you will probably end up seeing other caution lights come on. Then, you determination have to see a mechanic for what is called "forced" renewal. If you fail to do this, then the soot load is just going to keep on increasing.
in conclusion, your car will stop running correctly, and at that point, yes, you will be look at a safety issue, because you will see decrease performance level when you are trying to do maneuvers like passing and merging on the highway. This is where "probably" comes in as far as safety is concerned. You will also likely end up incurring very costly repairs.
