Particulate filters what a joke
Discussion
Quite amusing,the new "Euro" diesel particulate filters,(the one that if not fitted to a diesel engine prevents access to the city or any low emmision zone) are apparently now required to be retro fitted to early commercial vehicles for the sum of £1400!
These contraptions on older engines block up and cause bad running and poor emmisions.....the fix?......do a few miles at 50-70mph in a low gear to clear them out,you couldnt make it up,hence releasing all the carcogenic particulates back into the air again,unbeliveable.

What private vehicles do they have to be fitted to and in which country is this?
Sorry the post is confusing the vehicle which prompted the post was a L200 which was debateable whether its classification was private or commercial and is related to its date of reg also my mistake!However give them time!

In some German cities they already have this (After all it is based on EU regulations)
They have red, orange or green tax-disc sized stickers in the windscreen that you have to pay for every year. There are signs at the side of the road denoting which colour disc is allowed past.
I see the same signs around London for larger vehicles are now in use (after spending several years covered up)
DPFs are very unreliable, but when retrofitted (and so not well integrated) to older vehicles they are a complete disaster as the engines are old and not designed to work with them, so smoke more to start with and also have no forced regeneration regime in the ECU.

Ive also heard of certain "types" hacking them off as @ £1500 a pop they are very sellable and not (at present) id marked!!They have red, orange or green tax-disc sized stickers in the windscreen that you have to pay for every year.

Some of the lads at work have chipped their oil burnes and say they pull better, run cleaner no longer blowing black soot and use less fuel!
One said his Dad's 407 started to bog down, so he took off the exhaut and steam cleaned it out.
That cured it apparently and loads of black crap was washed out!

On my Wifes' old diesel C5, we had 'Anti-pollution fault errors. I took the DPF off, knocked the insides out, (10 minutes with a masonry drill/old trolley jack handle & a hammer). Refitted. Luckily I have a mate with a copy of the Peugeot/Citroen computer prog & leads (£100 off ebay should you wish to buy one) We simply plugged in and turned the option that said "DPF Present" to OFF. Since then, about 6k, the car goes better, does 5MPG more & has passed an MOT. It is a 2001 car, probably one of the first diesel cars with a dpf in the UK.
This is a 100k mile car, that spends its' life on the motorway, not doing city driving.
This is what it looks like gutted, the bin liner contains the insides, it is a brick like substance.

There is no evidence that the particulates are carcinogenic.

The question now is will it pass an mot next year as this is one of the requirements being introduced , iI was astounded to be told by my garage (good indy ) a couple of weeks ago about the changes due.This is a 100k mile car, that spends its' life on the motorway, not doing city driving.

the mot already includes OBD connector to interrogate the ECU for errors or allegedly "illegal" tweeks .

This is correct.
Is that not the same? This residue is expelled to atmosphere by increased engine RPM generating extra heat and pressure the black smoke is clearly visible when doing this.The clue is in the word 'particulate'.
If you think about it, it is obvious. The DPF are not catalytic nor do they permanently trap anything, just hold the particles until they burn off.

FTFY.Still, serves all those idiots right who bought a diesel for their short journey town use 'because it gets better mpg'.

No. The extra heat burns off the particulates, which are expelled as gas.

So in perpetuity the particulates of partially burnt carbon deposits (which are carcogenic like old engine oil)just dissapear never returning to the atmosphere,have you actually seen inside a clogged DPF on a tired old engine?The clue is in the word 'particulate'.
