The dpf and
the egr are too different things. I removed the dpf to get rid of problems but
my egr is still working. The egr doesn't make as many problems as the dpf. It
actually makes no problems if you clean it regularly, say once a year, which I
do myself – a two hour job.
Now, my dpf
is removed in such a way that no one is able to verify its removal. What I mean
is that the dpf unit was cut open and then welded at the top. This top part
then is placed right beneath the chasis, so you just can't see it was cut up. All
the sensors are in the right place so you may look at the dpf unit from
different angles, and you will see nothing suspicious. There is, however,
another thing - a smoke test. In <st1:country-region w:st="on"><st1

lace w:st="on">Poland</st1

lace></st1:country-region> there aren't different norms for dpf-equipped cars, which means all
diesels must go through the same norms, which aren't strict understandably. In
fact, a gay who conducts MOT in <st1:country-region w:st="on"><st1

lace w:st="on">Poland</st1

lace></st1:country-region>
has no idea if a given car has been equipped with the dpf by the factory or not. How should he know it? He
has no access to any software to decode my VIN. Do they (MOT) have this data in
the <st1:country-region w:st="on"><st1

lace w:st="on">UK</st1

lace></st1:country-region>? So, in Poland, if during an inspection they
see that a car is relatively new, they even don't do a smoke test as they know
it will go through with a positive
result (unless a car is smoky like a coal-powered locomotive). The first zafiras 2005 had no dpf and it was ok.
So are they gays at MOT able to check if your bus should have a dpf or not?
