WHAT IS DPF CLOGGING?
DPF Clogging is caused when soot builds up within the filter.
This can cause:
- Reduced fuel economy
- Limp home mode
- Dashboard warning light
- Rough idling
- Difficulty starting your engine

Is your DPF clogged? Do you want to avoid expensive costs?
HOW DO WE CLEAN THE FILTER?
We use a 2-step chemical system that is pressurised in through the DPF pressure sensor pipe directly into the DPF.
This means in the majority of instances there is no requirement to remove the DPF for cleaning.
MOBILE JOBS
We are a mobile DPF cleaning service.
On your drive, or outside of the office, we will diagnose your DPF issue and
perform our DPF cleaning solution wherever is most convenient for you.
ABOUT DPF CLEANING
Passive Regeneration
The DPF system is designed in such a way that when the engine is
consistently running at approximately 2,500 rpms or more
e.g. on a motorway, the exhaust gas temperatures exceed 350°C
soot particles are constantly being burned off without any engine
management intervention.
Active Regeneration
Where the vehicle is predominantly used for urban mileage the
exhaust gas temperatures fail to get hot enough passive regeneration
is no longer achieved, therefore soot particles are no longer being
burned off so start to accumulate inside the filter.
This leads to clogging of the filter and when a threshold is reached
the engine’s control unit (ECU) triggers the active regeneration at
its next opportunity.
Forced Regeneration
When the DPF system has exceeded a set level of
saturation it becomes impossible for the vehicle to
perform a passive or active regeneration.
A mechanic may at this stage attempt what is known
as a forced regeneration.
Unfortunately all too often forced regenerations will fail
or only be beneficial for a short period of time. Why?
Simply because either the saturation is too high or the
operator has not diagnosed and repaired the fault
causing the DPF system to fail the process.
If a forced regeneration fails its common practice you’ll
be told a mechanic that a new DPF is required and at a
huge expense. In most instances this advice, even when
it’s from the manufacturer dealers, is inaccurate!
