In a vehicle where it’s done automatically, it will happen while driving. Don’t turn the vehicle off while it’s happening. There will be some notification on the dashboard, and the engine will rev higher.<\/p>\n\n\n\n In some vehicles, a gauge is shown with the DPD particulate matter level.<\/p>\n\n\n\n During the burn, don’t park on long dry grass because the process can heat the exhaust up enough that it will set fire to the grass. <\/p>\n\n\n\n A filter can only be burned a certain number of times before it must be cleaned manually or replaced entirely.<\/p>\n\n\n\n The worse type of driving for clogging the DPD is low-speed driving. The DPD has a much more efficient burn at higher speeds when more heat can be generated.<\/p>\n\n\n\n DPDs can be degraded by using the wrong type of oil. Check the manufacturer’s recommendations.<\/p>\n\n\n\n <\/p>\n","protected":false},"excerpt":{"rendered":" To reduce exhaust emissions, newer diesel vehicles come with a DPD (diesel particulate diffuser), which is also called a DPF (diesel particulate filter). They trap and burn off particulate matter (soot) from the exhaust gases.
