What is a DPF and what does it do?


In Layman’s terms, a DPF (Diesel Particulate Filter) is a soot trap located in the exhaust that catches harmful soot particles to stop them entering the atmosphere. These soot particles build up over time so the DPF is designed to clean itself during a process called regeneration.

If the DPF is blocked then the vehicle is either unable to self clean itself (caused by a system/conditions problem) or the DPF is able to self clean but it can’t do it quickly enough due to excess soot entering it (this would indicate a mechanical issue upstream of the DPF).

A DPF is a self cleaning filter that should take care of itself.

What is a DPF Clean and why do I need one?

DPF cleaning is a process that we carry out in-situ using chemicals to clear excessively blocked DPF’s. This procedure should only be carried out AFTER the root cause of the DPF blockage has been repaired otherwise the DPF would quickly block up again. Imagine that you have a flooded kitchen and you start to mop the floor without first turning the the tap off that is causing the sink to overflow…
