Do you see many cars with dpfs removed still managing to pass emissions just out of interest?
I used to see cars with cats removed still meeting required emission?

I tested a shitty old Zafira a couple of weeks ago, the DPF had recently been off and there was a big area of weld on the top so I would say it had been gutted.
It failed miserably on the smoke test and a few other bits, turns out it had been remapped too.
It hasn't been back for a retest.

Well its had its 10 working days for retest and I had a nosey at MOT history on Saturday and it hasn't had a test anywhere since.
I left it a nice advisory "Particulate filter appears to have been tampered with"

Would imagine if remapped right there wouldnt be a problem... the generic remappers may suffer now...
I wouldnt run a car with dpf... there nothing but trouble
Lads on our car scheme have issues with brand new cars with dpf s

I've found that life I needed.. It's HERE!!
Then it goes on to say
Undeclared illegal modifications (like removing a diesel particulate filter) could also invalidate a vehicle’s insurance, so it’s not just garages who could face serious consequences.
So if your mod is not a illegal mod i.e. Removing a useful part (dpf ) then its aloud
Which is a contradiction of the sentence before ( above ) maybe ??

But if it passes emissions tests and is covered up by a undersheet the tester cant start taking the car apart
They cant police it... theres 1000s of cars out there with them removed
Why would anyone detune their car and put a dpf back on
Id put money on dpfs, egr valves etc being main issues on modern diesels

I used to have an Audi A3 tdi and I had the dpf removed and the car was remapped.
It passed the emissions at mot time with no problems.
Not only could you barely see the filter as it's tucked up the back of the engine but it was gutted from the original system so visually you couldn't even tell it'd been opened and removed internally.
You would of needed to remove the system to check if it had even be tampered with to prove it had been removed which let's be honest wouldnt happen.
If it's a clean roadworthy car that passes it emissions and you can't tell it's been tampered with then no one would ever know.
It also says in that article your insurance 'could' be void, not will be void.
Like many other menial rules and regulations imo it actually doesn't make much difference.
You could even just claim you know nothing about it being removed.

People taking the mick with DPF removal will ruin it for everyone. Air quality has become a very serious matter, with between 20 and 40 thousand deaths a year annually in the UK linked to PM2.5. Chumps arsing about with DPF's will end up getting all engine mods banned like in France.
If people cant afford to run and maintain a car properly, then they're driving the wrong car. 30 years ago these are the people who used newspaper and chicken wire to support the Plastic Padding smeared into their sills - they've now moved their bodgetastic attention elsewhere. Thank God they don't try and 'mend' the brakes.

I refuse to do deletes, just won't get involved in it. If the tune is suitable there is no reason to get rid of them in reality,
I get asked all the time for removals, my answer is simple, either the car is not being used as intended, or has a mechanical problem causing smoke which is blocking the DPF. Low and behold, most come back once they have found someone to do a delete, cars smoking like a pig, guess why the DPF was blocked
Its easy to tell cars that have had a removal done in most cases, if you tap the filter, they go "clang clang clang" rather than "thud thud thud"

It stores up the particulates, and periodically uses one of several tricks to raise the DPF temperatures and it actually burns them off so they are vapourised and emitted as gasses. They don't simply open a trap door and blow a pile of soot out the tailpipe when the car is on a motorway.

I was on the M27 motorway today and a 2008 3 series BMW diesel was in front of me pouring out black stinking smoke. It pisses me off as the driver must be able to see it in his rear view mirror or notice the car isnt running right!! Just pig ignorant to not give a fuck about it!!

Reading that does make me ask what about diesels that didnt have dpfs fitted from factory? The likes of a vauxhall vectra for instance you could have fitted or not from factory so how would a tester know in that instance?

Andrew Giller was quoted ÂŁ1,000 for a replacement on his seven-year-old car - and he had to get it done four times in quick succession because it kept getting clogged up.
He said: "The car manufacturer should play a responsible part and guarantee the DPF filter for the life of the car.
Must be something properly wrong with his car or it never gets over 30mph pottering around town trying for 70mpg 😂

Cars had dpfs before 2009...
2005 I think they started fitted them to some cars

In the news today, the government are looking at tightening the MOT rules with other tests to detect if the DPF has been removed. They haven't said what methods will be used, but claim they'll be introduced during 2018. Not before time either, because people have been taking the piss out of this for ages.

Ive said it before on here. Had no end of issues with mine . ending up smashing the guts out and having the ecu edited to not sure up anu issues. Looks wise it was all there when under the truck and mot'd fine.

If they think what VW did was a scandal...whoever came up with these stupid fucking things is an even bigger scandal.
And so are the morons pushing for unrealistic emissions targets.
If emissions are so important to them, then the technology needs to be reliable, and not pieces of shit that fail often and cost a bloody fortune to repair. The EU are to blame for all this nonsense !

My father in law has had 5 dpf equipped cars and my wife has had 4.
Neither of them have had a problem as they were/are sales reps racking up big miles using diesels as they are now intended.
Problems occur when you are pootling about the city and not getting up to 60 mph for a long enough period for the dpf to regenerate itself or when the engine is remapped.

My friend almost makes a living as a mobile diagnostic expert going around various garages force regenerating dpfs.
He’s an absolute wizard with modern electronics and diagnostics but the issue he sees most across every brand of car is dpf faults.
He won’t touch a car that’s had a remap as the base settings are gone and he can’t read what the car tells him.
Taking a diesel for a back toad thrash doesn’t work either,they need a steady prolonged cruise to regenerate themselves.
Vw’s fix for their emissions scandal made the cars uneconomic and cause more dpf faults over a non updated vw.

A good remap won't cause DPF issues, it only when they produce excessive smoke you generally get issues, or doing EGR deletes without realising that the DPF requires an active EGR to regen.
The DPF itself prevents the driver knowing the car is smoking after a bad remap. Rouge Tuners best friend, as once the issues show themselves the rouge has long gone.
To measure the emissions in order to determine if the DPF is present is easy, At vosa we were using machines capable of this to test trucks for suitability for the LEZ Low Emission Zones, and they read fine particle matter,
The issue is the machines were expensive and time consuming to use as they has to be cleaned often.
The technology is there though to measure if a DPF is present from the tailpipe

I think the day of the diesel for anything but trucks and trains is long gone now. Working in the motor trade for over 20 years now Iâve never seen so many problems with diesel cars than I have done the last few years.

Was talking to my friend this morning and he says the taxi test center in Glasgow has a dpf detector there to check for dpf removal when the taxis get their police test.
He said dpfs are a necessity on a modern car and should never be removed,if you are having dpf problems then buy a petrol as a diesel is no use for the journeys you are making.

Trucks were reliable at euro 5 with ad blue now euro 6 means ad blue and egr to meet targets the egr system is nothing but problems with trucks that don't work hard.

We have a 2006 Seat Leon FR as our daily... the management uses it for work everyday - it's now on 130k. I've often thought of getting a DPF delete and remap for better economy and more performance.
I remember from about 85,000 to almost 100,000 miles the coil light was flashing all the bloody time. I could get it on the motorway about 55mph, sit the revs high and the light would go after 15-20mins.
After that period I told her not to worry about mpg, not be careful though the gears and drive it normally. She's been ragging the arse off it 13 miles to work and 13 miles back most of those journeys (apparently still quite a short journey for a diesel? ) for the last 30,000 miles and it's not been problem, touch wood.
So what I've learned from this is to be economical in a diesel you have to drive sedately and low down the revs, but you can't because it f**ks itself.

My brother’s 2009 Mazda
Must have owned it 3-4 years
Been plagued since the day he bought the piece of sh!t with egr and dpf issues
Had to be fetched back via flatbed on many occasions...
Today was no exception
Broke down a hour away from home @ 15:00
Breakdown have just finally got him home after they sent someone out to look at it, decided there’s nothing can be done at roadside so sent for the flatbed
Told him not to buy it ( that’s another story ) also said best thing he could do was egr, dpf delete and a remap...
He won’t listen...
Dpf filters save the planet, not when this happens again and again and again
The car would be reliable if it was all deleted...
8 hours spent getting recovered to do a hour journey home when it’s rained all day with family in the car can’t be fun...!
