Some thoughts about dpf delete for those of you that are thinking of dpf, ad-blue delete.
I was searching the internet and found this and other threads about a delete.
Below here is a link to a Swedish article (can be easily translated to english) about DPF deletes and the Swedish MOT.
In short what it states is that
”You can gut out your dpf until it is an empty can and still be able to pass MOT” (in Sweden)
Sedan Transportstyrelsen höjde gränsvärdena går långt fler fordon med höga utsläpp igenom besiktningen. Enligt branschen är Sverige sämst i Europa på att kontro

I have seen many replies on different forums that the dpf is there for a reason. To save the environment. I agree but have a different approach. My opinion is that it is there for a political reason. And the automotive industry was reluctant until legislation. And now the retailers are making money on a very complicated system.
If you can drill it out the dpf and still pass MOT with an opacitytest then why do you have dpf’s?
After quite some reseach all over the internet I have found statements that suggest
1) euro 5/6 particulate filters makes more NOx than earlier models
2) more NOx then has to be lowered (do they really?)
3) NOx lowering in euro 5 leads to higher fuel consumption
4) NOx lowering in euro 6 with urea injection leads to ammonium in exhaust gases and they seem to be very bad for plantlife (what about humans?)
5) NOx is not bad for plantlife. That is why you find so much flourishing greens after roads
6) NOx is not bad for humans. Nitric dioxides is unfortunately.
7) Humans have glands in the nose that secrete NOx when you inhale. Please do a search for Nitric oxides health benefits.
8) Dpf euro 5/6 only lets small particles pass and according to new studies these small particles can pass into the bloodstream of humans making them up to 1000 times(!!!) more carcinogenic than older diesel cars.
9) Political legislations often lead to consequenses that are worse than the initial problem they were supposed to solve.
I am fully aware that exhaust gases are full of other harmful stuff. This is much more complicated. My question is do NOx levels really have to be lowered?
The most aggressive greenhouse gas is water-wapor. Water droplets attach to small particles. What about large particles like diesel exhast particles? Do they creste more humidity in the air? I don’t know. Does anyone know?
Unfortunately when it comes to scientific research some claim that up to 84% of research is flawed or completely wrong.
But they could be wrong!
Hope this helps those reading this thread and are thinking of dpf delete to make a decision. I have not done a dpf delete myself. Atleast not yeat. Have done a dpf flush for now after a turbo change. Will see what happens in the future.
