Should you delete your D.P.F ?

This fellow is also the same idiot who stated you would need 18 100 amp hour agm batteries to do and last like one of the DCS lithium they were flogging. I didn't view the clip...as soon as I saw the blokes head I thought ..."oh no no this wanker again"...

you are dead right there Bigfish ... the sign in the left hand top corner says it all .... bunch of pillocks
... LOL :)))

Probably the same mentality who call a money dispenser, an ATM machine/machine. I regard the one from the 4WD magazine as being as credible as a vegetarian shark. Most likely why I never look at or buy 4wd mags.

Yeah nah, perhaps I stayed at the pub a bit too long tonight and buggered up my comprehension skills a bit, but surely if you are nitpicking, then you would be able to string a sentence together to make a little bit of sense at least. The following sentences just don't really say anything meaningful.

"But the point of not bothering to remove it as it won't gain you anything and potentially cop a sizeable fine".

"Probably the same mentality who call a money dispenser, an ATM machine/machine".

Well done troopy bloke...hopefully your the last of the English Grammar and Spelling Police whose input is so valuable!!

Really? Why nit pick over the post. Most on here find it unnecessary and pointless. I thought we,d moved on from this sort of rubbish.

All mentioned in the video

If the affected part had absolutely nothing to do with the accident your insurance wont bother you. Bit like having a broken brake lens (illegal..therefore unroadworthy) and you run off the road and hit a tree! You will be covered by insurance.

Bigfish,

I humbly suggest you check your insurance policy. I’m pretty sure that it will state that if you vehicle is unroadworthy, therefore illegal, then they do not have to pay.

Phil, you can't really blame a manufacturer for a DPF failure, when it was caused by faulty installation of an intercooler pipe.

However, having said that - I firmly believe DPF technology is the greatest emissions control, technical and engineering failure, that has ever been foisted on long suffering diesel owners, since emission controls were invented.

DPF is on a par with the early emission controls on petrol engines of the early 1980's.
Remember the retarded timing camshafts, the air pumps, and all the other useless devices that caused maintenance to increase, power outputs to decline seriously, and fuel consumption to decrease?

It wasn't long before people were throwing all that crap in the bin, too. DPF's belong there, as well.

I'm all for cleaner exhausts, but there must be a simpler, less costly, and lower maintenance system than the current DPF technology, that would get awarded a big "FAIL", if it was ever entered in any engineering invention competition.

Cheers, Ron.

There is an answer Ron...it will be the hybrid engine that is starting to appear more and more often...like it or lump it but this will be the future. My mate eliminated the dpf on his NS Pajero. No big job and car runs like a ripper. 200000 klms and he,s never had to lift a spanner to it apart from regular services.

Bigfish. Hope he never gets checked by the cops. EPA fines are usually very large.

Cops wouldn't have a clue if your dpf is deleted unless they put a scan tool on or crawl under car and have a good knowledge of exactly how the dpf is turned off. No different to the many hundreds of thousands of motorists who knowingly tow over weight vans, those who have turned off the egr, those running too big a tyre, those with illegal headlights, those with illegal lift kits, those with modified exhaust..ad. nausea. Biggest cock up in motoring nowadays is the dpf. Even Toyota cant get it right!.

Everyday people make mods that are illegal. I haven't heard of one person getting done for deleting the dpf...would be interested to know the numbers.

Did you even watch the video? He said he was pulled over for an RBT and cop looked under his ute for a DPF.

It was only yesterday I was showered in black smoke from a landcruiser as it must of did its burn thing when he was half way past me, SOOO, all this black crap that's let go is not polluting anything??

Can't see it myself!


Cheers &HNY

Axle.

My mates dpf looks factory...also you can delete with an ecu remap very easily...Now unless a cop actually hooks up a scanner to your Obd2 port I think you will be safe..

"He said he was pulled over for an RBT and cop looked under his ute for a DPF." Sounds like bullshit to me..especially for a RBT stop. Sorry mate this bloke and the advertisers dont cut the mustard with me.

Ron, speaking of air pumps - the SG Forester (03-08) used air pumps on the turbo models. For the first 90? secs (ECU timer) after starting, two valves open and the air pump feeds into the exhaust system. The whole purpose is to meet emission standards for nitrous oxides. The majority of owners bypass that entirely, but it needs an ECU "code delete" patch to avoid a permanent code/display.

The whole system is there because the stupid regulators saw % emission as the easily measured parameter, and of course that can be met by this simple "dilution" approach.

Can you name one other thing on a car that if compromised by a loose clamp would cost over $3000 to replace?

Rangiephil
If an intercooler pipe came off, ie, the one he had replaced and was subject to faulty installation, the IMMEDIATE drop in power would have been very noticeable. I presume a code would also appear at the same time. Instead of rectifying the issue he drove it 100km in limp mode? He already was smart enough to replace the hose. The ECU would instantly detect the loss of boost and limit fuel injection, amount to minimal. Did the DPF get filled because of overfuelling? Was he advised to replace it or was a burn off sufficient and lower cost too. Maybe removal and cleaning may have rectified the situation. Most dealers will replace of course as they make plenty of cash from doing so. Perhaps driver error in operating the vehicle in a faulty condition is the cause.

You don't need to be a rocket scientist to see if someone has deleted the DPF. Run your finger around the inside of the exhaust pipe; the deleted one will leave your finger black with soot.
With the DPF still connected, you will only get a faint dusting. My 18 diesel v8 cruiser has not had the DPF deleted, faint dusting. My mates 17 diesel v8 has had the DPF deleted and the exhaust is very black.
Any not so smart copper would know this. If you have heaps of dough delete. Rob J

"Can you name one other thing on a car that if compromised by a loose clamp would cost over $3000 to replace?"

The engine?

"Can you name one other thing on a car that if compromised by a loose clamp would cost over $3000 to replace?"

Yes - leave a clamp loose on an intake pipe between air cleaner and engine, and in dusty conditions, you'll soon have a "dusted" engine, which will cost you a lot more than $3000 to fix.

One of the major problems with DPF's is that they are simply a vastly overpriced part for what is in them.

They contain a honeycomb formation comprised of mostly cordierite compounds, and they can't be as expensive to manufacture as the pricing is trying to make out.

They have to be a "nice lil' earner", as Arfur would say, for the manufacturers.

I can't see why there is a need to burn off the soot deposits in the DPF. Surely a simple filter device that catches the soot particles, and which filter is then simply disposed of in the normal landfill system, would do the job.

A simple centrifugal-style filter, often used by older engine manufacturers such as Deutz, to filter oil, would work on soot particles. The old air-cooled Deutz diesel, centrifugal oil filters, worked a treat.

But then again, I'm not an automotive manufacturing engineer, with instructions to design a high-maintenance device, that is easily destroyed, that provides a continuing, substantial, high-profit-level income stream, for manufacturers.

Cheers, Ron.

The beauty of it...it normally occurs mostly outside of warranty period!!!

I think a cop would only have to look at the exhaust tail pipe and if it was covered in soot he may put it off the road


Myles

So pre DPF’s engines were spewing those highly toxic particles out, for how long have diesels been around?
So all previous diesel drivers have been squirting poison in stranger’s faces. we should all be dead!
I don’t think DPF’s have made the world that much safer!

No DPF's here, strangers are lining up to get squirted in the face

You should present your scientific findings to the car industry so they can pass them on to the relevant authority and get rid of DPF's. They probably haven't thought of it. Doing so would save them millions of dollars.

Hey Michael H9
You’re the one saying “scientifically determined “

That's correct, multiple scientific studies world wide have determined that diesel particulates in the exhaust contain a cocktail of class 1 carcinogens that have proven to increase cancers and lung disease in those who come in contact with them. Hence why government regulations have been introduced forcing car makers to try and filter out the poison that's spewing into the air. It's criminal to knowingly bypass this if you know you are spreading toxic substances in the process. It doesn't matter if they were spread in the past, nobody knew, but now they do. My grandmother smoked cigarettes until she died at 88. That doesn't mean cigarettes aren't bad for you. Diesel exhaust is the same situation.

Michael H9,

“Spewing poison into the air” is not restricted to Diesels engine exhaust. Petrol engine exhaust contains many deadly compounds as well, Carbon Monoxide being just one.

Macca.

Carbon monoxide isn't a carcinogen. Petrol is a lighter fuel and burns more completely than diesel, much like lpg burns more completely than petrol. The danger with diesel is the particulate matter, the soot if you like. Scientific studies and analysis have determined all this, not Fred down the pub. If petrol engines were producing the same particulates then rest assured they would be required to have a filter as well, but studies have found they do not.

The regulators aren’t just aiming at carcinogenic materials , it’s about the climate changing stuff too. Therefore carbon monoxide is in amongst it I presume.

Well carbon monoxide comes out of all engines, but it's carbon dioxide levels that are mainly causing the climate change problems, (allegedly), and it comes out of any petroleum based car as well. Anyway, those compounds have nothing to do with DPF's and whether we should be deleting them or not. It's a big deal, VW has been fined a motza for rigging their diesel emissions testing procedures and also got into trouble for using monkeys in experiments to test the effects of breathing diesel particulates, probably in an attempt to prove there's nothing wrong with smoking diesel fumes?

Michael,

I did not say that Carbon Monoxide was a carcinogen, merely that it was a poison that was being spewed into the air from petrol powered vehicles.

Macca.

The authorities haven't determined that carbon monoxide is deadly enough to require a filter that in turn some people might want to bypass. The thread is about DPF blocking and I was saying that if the particles are deadly enough that the authorities want them filtered out, then we shouldn't be removing the filter. It's pretty simple to understand. Having people on here saying that diesel particulates are harmless and that "I don’t think DPF’s have made the world that much safer!" doesn't fly in the face of scientific research.
Any other deadly chemicals can be the topic of another thread, perhaps climate change......that would fire up a few boilers.

If we're talking deadly, then just driving the car on the road is more dangerous than anything else.

We better stop using unleaded fuel as well because it contains the carcinogens benzene, toluene, naphthalene , trimethylbenzene , methyl tert-butyl.

Are you saying we shouldn't worry about DPF's because there are other carcinogens in the world? I'm trying to understand the relevance of your statement in a thread about diesel particulate filters and the dangers of diesel soot. All of those other compounds are in diesel too but aren't required to be filtered out because the same level of health concern isn't there for them.

No Micheal, not saying anything about dpf's at all, just informing on the carcinogens in unleaded fuel.

On dpf's, people are using the diesels for the wrong duty. They run around town and do short trips, truck engines that have been speced for the correct duty cycle only have to have their dpf's cleaned around 300,000 to 400,000 Klm's.

9900Eagle. This is the reason my Dmax has never done a burn in 18,000IKm since new

Jackolux
The belching smoke as the accelerator is pushed, clearly shows the unit has been fiddled with. Plenty of Nissans do it std though. They go ok until they stop. None of which is to do with a DPF , but having it overfuel, every time power is asked for is stupid and a dead giveaway to official observers. I think most remappers are simply folk learned enough to alter maps and who want to make a $ and have poor understanding of diesels. ie, go fast boys playing with diesel.

Yep, I'm sure the owners of vehicles fitted with blocked and fault-producing DPF's would be happy to pay you your $120 hr, while you farted around all day, fault-finding and cleaning, and probably costing them around $1000, trying to fix a shonky device, that is problem-ridden from Day one.

The problem is that it's likely about half the mechanics out there, can't even diagnose or repair DPF faults.
They are "parts and component replacers", that's about all they are today.

There is no such thing as "repair" with todays high-tech vehicles, you are simply told the offending part is stuffed, and they'll order in a new one.

I buy vehicles for their simplicity, and ease of maintenance, and low cost maintenance. Vehicles fitted with DPF's don't fall into that category.
And that's the reason I don't have a vehicle with a DPF, and I'm not likely to ever buy one with one fitted.

The world is full of sucker new car buyers who want the latest technology. But in todays world, if you buy the latest technology, you're the test bed for that latest, high-tech, overly complex technology.
