Diesel Particulate Filter Regeneration: When, Where And Why?

The Diesel Particulate Filter (DPF) is a ceramic brick with tiny passages that do two things. First, they trap the particulates or soot in the exhaust. Second, these passages create the surface area for the precious metal that helps to burn or break down the particulates. Think of it as a catalytic converter that traps and oxidizes particulates in the exhaust. But, the DPF regenerates in intervals rather than all the time like those found on gasoline vehicles.

First Generation Kia Soul Brake Job

Brakes on the Soul are conventional single-piston calipers and four-wheel discs on most trim levels and very straightforward to service. Some of the basic trimmed models had drum brakes in the rear.
