Is a DPF and EGR the same thing? Diesel Particulate Filters and Exhaust Gas Recirculation systems (DPF and EGR, respectively, for short) are both designed to limit harmful emissions.

Does removing DPF cause problems? Removing the filter doesn’t affect the car’s performance, and some motorists even state they achieve better fuel economy and engine performance without one.
