Product A diesel particulate filter (DPF) is a device which sits in the exhaust system, it “captures” soot / diesel particulate and other nasty particles so they are not released into atmosphere. A diesel particulate filter can remove upwards of 85% of the particles from the exhaust, reducing harmful emissions. The DPF physically captures the soot Engine temperature >75 °C (normal operating temperature). Exhaust-gas temperature upstream of the diesel particulate filter>240 °C . Sufficient fuel present (fuel reserve lamp is not lit). Regeneration is aborted if the fuel reserve lamp lights up. No fault code concerning air, exhaust gas, or sensors stored in the DDE. However, eliminating the diesel particulate filter has numerous benefits, including improved horsepower, better fuel economy, etc. However, the major drawback of DPF delete is the possibility of releasing toxic gaseous emissions into the atmosphere. This can pose a serious threat to the environment, especially to human health. Here are a few general ideas about the parts and labor cost for each repair.
