DPF Removal

DPF Removal
No More Warning Lights, LIMP Mode, Regeneration Or DPF Problems EVER AGAIN!
Are you having problems with your DPF (Diesel particulate filter)? Facing
expensive repair costs? Sick of poor MPG when the DPF is regenerating ? Want to
remove the DPF from your vehicle? Then you have come to the right place, we can
alter the software in the ECU (Engine Control Unit) so that the DPF can be
removed from the vehicle without logging any error codes or attempting any
future regeneration

DPF Removal benefits include:
Increased MPG
Better Performance
No expensive repair costs

More on DPF Removal
Diesel Particulate filters (DPF) or ‘traps’ do just that, they catch bits of
soot in the exhaust.
As with any filter (think of the bag in your vacuum cleaner) they have to be
emptied regularly to maintain performance. For a DPF this process is called
‘regeneration’ – the collected soot is burnt off at high temperature to leave
only a tiny ash residue.

When the dpf warning light is displayed on your vehicle its because the
regeneration process is failing and the dpf filter is blocked if you continue to
drive the vehicle in this state eventually your vehicle will lose power and go
into limp mode and potentially causing more damage to your vehicle and end up
costing a fortune to put right.

In addition to collecting the particulate, a method must exist to clean the
filter. Some filters are single-use (disposable), while others are designed to
burn off the accumulated particulate, either through the use of a catalyst
(passive), or through an active technology, such as a fuel burner which heats
the filter to soot combustion temperatures, through engine modifications (the
engine is set to run a certain specific way when the filter load reaches a
pre-determined level, either to heat the exhaust gases, or to produce high
amounts of NO2, which will oxidize the particulates at relatively low
temperatures), or through other methods. This is known as "filter regeneration".
Sulfur in the fuel interferes with many "regeneration" strategies, so almost all
jurisdictions that are interested in the reduction of particulate emissions, are
also passing regulations governing fuel sulfur levels.

DPF Maintenance
Filters require more maintenance than catalytic converters. Engine oil ash
builds up on the surface of the inlet face of the filter, and will eventually
clog the pores. This increases the pressure drop over the filter, which when it
reaches 3.7 pounds per square inch (24 kPa) or higher it is capable of causing
engine damage. Regular filter maintenance is a necessity.
Regeneration is the process of removing the accumulated soot from the filter.
This is done either passively (by adding a catalyst to the filter) or actively.
On-board active filter management can use a variety of strategies:
Engine management to increase exhaust temperature
Use of a fuel borne catalyst to reduce soot burn-out temperature
A fuel burner to increase the exhaust temperature
A catalytic oxidizer to increase the exhaust temperature, with after injection
Resistive heating coils to increase the exhaust temperature
Microwave energy to increase the particulate temperature
All on-board active systems use extra fuel, whether through burning to heat the
DPF, or providing extra power to the DPF’s electrical system, although the use
of a fuel borne catalyst reduces the energy required very significantly.
Typically a computer monitors one or more sensors that measure back pressure
and/or temperature, and based on pre-programmed set points the computer makes
decisions on when to activate the regeneration cycle. The additional fuel can be
supplied by a metering pump. Running the cycle too often while keeping the back
pressure in the exhaust system low will use extra fuel. Not running the
regeneration cycle soon enough increases the risk of engine damage and/or
uncontrolled regeneration (from an excess of accumulated soot) and possible DPF
failure. Quality regeneration software is a necessity for longevity of the
active DPF system.
Diesel particulate matter combusts when temperatures above 600 degrees Celsius
are attained. This temperature can be reduced to somewhere in the range of 350
to 450 degrees Celsius by use of a fuel borne catalyst. The actual temperature
of soot burn-out will depend on the chemistry employed. The start of combustion
causes a further increase in temperature. In some cases, in the absence of a
fuel borne catalyst, the combustion of the particulate matter can raise
temperatures above the structural integrity threshold of the filter material,
which can cause catastrophic failure of the substrate. Various strategies have
been developed to limit this possibility. Note that unlike a spark-ignited
engine, which typically has less than 0.5% oxygen in the exhaust gas stream
before the emission control device’s), many diesel engines run above 15% oxygen
pre-filter. While the amount of available oxygen makes fast regeneration of a
filter possible, it also contributes to runaway regeneration problems.
So if the warnings are ignored the filter can clog up past been able to be
regenerated. And they cost £1000+ to replace from the dealers.

DPF Removal / Diesel Decat
It is fully legal to remove the catalytic converter from a Diesel Car and it
will not raise any issue at MOT time. VOSA, who run UK MOT testing have
confirmed this with us. This also applies to DPF (Diesel Particulate Filters),
which are not even mentioned in the testers manual.
In January 2012 there was a regulation change for cars that require an emissions
test where ‘if a cat was fitted as standard, it must be there for the MOT’.
Diesel cars are not required to pass this emissions test, so that regulation
doesn’t apply. There are no further emissions related changed expected in the
near future and any changes to emission tests are unlikely due to the massive
cost to the MOT stations.

What we do to help?
The DPF filter cannot just be removed as your ECU will look for it and warning
lights will show up. We work with some of the worlds leading ECU programmers to
produce software to stop the ECU looking for your DPF, then the DPF filter is
physically removed from your exhaust system.

Here we have successfully removed the DPF filter on all makes and models of
vehicles. With hundreds of satisfied customers you can rest assured your vehicle
is in good hands
We can save you thousands on costly dealership prices who will tell you that to
solve this dpf problem is to replace the filter which costs in excess of £1000
The work we do will come with a lifetime warranty on the software as we write
our own maps in house to suit your vehicle and keep the original files to your
vehicle in our data bank for any future reference.
We offer same day service and aim to get your car back to you ASAP as we
understand how incontinent it can be to be without a vehicle.
Having the DPF filter removed will not affect your mot tests or any day to day
driving it will benefit your vehicle
Benefits of DPF Removal:
Increased MPG
Better Performance
Improved Performance
Avoid Expensive Repair Costs

It’s been brought to our attention that some companies are now offering DPF
delete services using cracked software and in some cases not even removing the
blocked DPF element from the exhaust system which is very dangerous for the
engine! We have been carrying out DPF removals longer than any other company in
the UK. Come to the professionals and have the job done right the first time! We
are a registered company and offer you a lifetime guarantee with all our work.

Mobile DPF Removal service available. We can help your garage or service centre.
