why is my dpf blocked?

When your Diesel Particulate Filter (DPF) is blocked your vehicles exhaust is restricted.

This could be caused by 

· Short trips – not  giving enough time for the DPF to self regenerate

· Wrong engine oil used ( oil must be the same specification as the manufacturer recommends)

· The diesel engine is producing too much soot and overloading the DPF (numerous causes)

· Oil is leaking from the turbocharger into the exhaust and is being burned by the DPF

· The engines automatic DPF regeneration system is not working properly (numerous causes)

· Melted and or physically damaged DPF. In this case the DPF needs to be replaced.

· The DPF has too much ash after many regenerations (or wrong oil used) and must be
physically cleaned off vehicle to remove this ash from the filter

· Or any combination of the above

Diesel particulate filters are expensive to replace usually costing many thousands of dollars.

Before you send in your DPF unit for cleaning it is very important to diagnose and rectify the root cause of the blockage from the above list otherwise it will block again in a short period of time.
If this is not carried out there is no warranty.

At DPF Cleaning Melbourne we will inspect and if it is not damaged, clean your DPF filter and restore it to almost new capacity saving you thousands of dollars on a replacement unit.
