Why Should the Diesel Particulate Filter Be Cleaned?

1. What Does the Diesel Particulate Filter Do?

Diesel particulate filters (DPF) are fitted on diesel vehicles from 2009 onward.

Diesel particulate filter prevents harmful gases from entering the air directly while the engine runs. It is environmentally friendly and plays a major role in reducing air pollution. Some Euro4 vehicles use filters; Euro5 and Euro6 use full DPF systems.

2. Why Does the Diesel Particulate Filter Clog and How Is It Cleaned?

The diesel particulate filter faults after a certain mileage. Typical symptoms:

Increased fuel consumption
Bad smell from the exhaust in some cases
When clogged, turbo pressure drops and the ECU may log a turbo fault
Loss of vehicle power

What causes diesel particulate filter clogging?

Continuous low-RPM driving
Low-quality fuel and oil
Heavy city use
Long idling

Diesel Particulate Filter Regeneration with a Diagnostic Tool

When the diesel particulate filter clogs on passenger and heavy-duty vehicles, regeneration can be done with a diagnostic tool. Authorized workshops and universal diagnostic tools can perform this. On passenger vehicles Autel and Launch perform strongly. On heavy-duty groups Jaltest diagnostic tools excel. Regeneration is not a definitive fix; if the DPF is fully loaded it must be removed and washed.

Washing with Dpf Clean Pro is a definitive, guaranteed solution.
It washes passenger cars, trucks and construction machines.
Washed diesel particulate filters and catalytic converters are cleaned with water and fluid.
Dpf Clean Pro has manual and automatic modes; manual allows wash time, fluid, wash and dry settings; automatic gives recommended values with about 99% efficiency.
After cleaning, DpfCleanPro prints before/after values.
