What damage can a blocked DPF do?
Under certain conditions, a DPF can become blocked, causing an engine fault code to display. In extreme cases – especially if the fault is ignored – the blocked DPF will cause the car to go into ‘limp’ mode.
Can you drive with a blocked DPF filter?
Can you ignore the DPF light and carry on driving? Technically yes, but we would not recommend it. If you ignore the DPF light and continue driving, the build-up of soot will soon reach a point whereby your car has to enter ‘limp-home’ mode in order to prevent any damage to the engine.
Do you have to bake DPFs to Regen them?
We ALWAYS bake our DPFs as part of our cleaning process. Although DPFs are designed to be regen on the truck, perfect conditions don’t exist and baking ensures that compacted soot is loosened and able to be blown out of the unit effectively. The the Filtertherm® DPF oven was designed specifically to bake multiple DPFs.
Do you have to blow out DPF after baking?
Do an additional blow out / de-ash after bake to remove newly loosened sediment from the DPF. At any point in the inspection / cleaning process, re-bake the DPF if all of the soot was not converted to ash during the first baking cycle. This ensures the best results possible for your DPF cleaning.
What happens if you cant keep your DPF clean?
Bottom line is, if you can’t keep your DPF clean, you are going to have ongoing aftertreatment issues and repairs. The diesel particulate filter captures pollutants before they exit the exhaust stack. These pollutants build up on the ceramic of the DPF over time.
What to look for in a DPF filter?
Visually inspect the physical condition of the DPF, look for signs of damage to the substrate, cracks, is soot bypassing filter, hard ash centering, chemical / oil / wet / fuel / coolant soaked; cracked brick, cracked welds, dents in can, missing flanges.
