How do I stop my DPF from clogging?

The soot can block the filter, stopping the engine from running and leaving you with a repair bill running into the thousands. To stop this from happening, the soot needs to be burned at a high enough temperature to turn it into smaller ash particles, which can then be expelled from the system.

Can a blocked DPF damage turbo?

A blocked DPF can force exhaust gas through the smallest of gaps, including the clearances in the bearing housing VNT lever arm and turbine housing waste gate mechanisms. If this occurs, carbon build up in these mechanisms can restrict movement of the levers affecting performance of the turbo.

Not so much in the fuel system, but in the combustion area, emission components (EGR, DPF), and intake manifold, intake valves, etc. Using a premium diesel will undoubtedly delay the formation of carbon deposits in these areas.

How often should a DPF filter be cleaned? Generally, it’s recommended that a DPF be cleaned roughly every 150,000-200,000 miles. At this point, ash in the filter cells begins to harden. This hardening can cause the filter to crack, resulting in permanent damage.
