DPF (Diesel Particulate Filter) is an emission system that works in conjunction with the exhaust system of the vehicles, designed to clean and expel the harmful gases resulting from the combustion of fuel in diesel vehicles.Although the DPF absorbs the harmful gases from the engine and tries to throw them out, 80% is successful and the remaining 20% of the vehicles are blocked after a certain kilometer and warn the driver as a warning lamp on the indicator.Vehicle manufacturers perform Particulate Filter Regeneration to the vehicles in order to clean the amount of ash in the DPF during the periods when this part is clogged, but this is not a permanent solution. After an average of 30,000 km, the vehicles light the DPF Lamp again.This part needs to be replaced when DPF regeneration becomes impossible after doing several times on vehicles. The cost of this is quite high.
