Due
to popular demand, Motormech now offers a DPF removal service
in conjunction with an Engine Re-Map to ensure that the vehicle
still runs correctly.
We
can do this on all Alfa Diesels but for the following we can
offer this at a fixed all in one off price of £300 + vat
an normal.

Romeo 159 1.9
Alfa Romeo 159 2.4
Alfa Romeo Brera 1.9

Why
remove the Diesel Particulate Filter (DPF)?
The
DPF of your Alfa is designed to act as a filter for the exhaust
gasses in your exhaust system. It is designed to filter out
all the particulates from the exhaust that cause the "black
smoke" - the soot. In theory what should happen is that
as you drive around down it prevents you sooting up the streets
when you accelerate. Of course without emptying the filter it
would just keep filling up and block the exhaust, so each DPF
is designed to go through a process called "regeneration".
Regeneration occurs when the car is cruising along at a constant
motorway speed for example.
When
a DPF regenerates, in simple terms, the engine pumps in extra
fuel to heat the gasses and DPF up to such a level that the
soot collected burns off and empties itself by the side of the
road. Keeps the cities cleaner then pollutes the country side.
Each
DPF can only regenerate so many times, then it just stops. When
the filter reaches perhaps 40% full the car is in limp home
mode and you loose all power. The DPF will need to be replaced.
The DPF will fill up quicker if you ONLY do small city based
runs as it rarely gets the chance to regenerate.
Options
1)
Replace the DPF, at a cost of £1850 + Fitting
2)
Remove it all together. A permanent fix
Why
do you need a remap after?
Once
a DPF is removed and replaced with a bypass pipe (we only use
T304 Stainless steel) we need to in effect perform a "lobotomy"
on your car and cut the part of the brain out of the computer
that performs the regeneration. Once this is gone, that is the
end of the problems.
If
you just bypass the DPF and do not remap the car after, and
by remap we mean the program that makes your car move, run and
stop, the ECU will continue to try and regenerate and you will
just be pumping in the same rich fuel which will not burn properly
and you will be wasting money on expensive fuel AND your car
WILL smoke like hell!
Of
course there are great power gains to be had by not strangling
your engine with a DPF (some examples are listed above) and
assuming you don't permanently take advantage of this extra
power you will actually save money on fuel too.
Our
remapping works on your original Alfa Romeo File from YOUR car,
not some generic file. This is important, and preserves any
ECU updates your car might of had during services.
