Totally agree. The only people who even think about doing this are those who care far more about their pockets and car performance than they do about the lungs of other people. Why bother about killing off a few people when you can save a few pounds? I'm totally amazed that with all the VW publicity anyone should even consider this.

I have spoken to someone today and they said you can tell your insurance company about the dpf removal but they will see that as a high modification..... also if you had a accident the likelihood of the insurance company looking at your dpf, to see if it's there, is very very very low.

if you dont tell your insurance you will be driving the car illegaly and then if you do have an accident you deserve anything that does happen to you,you should know by now that insurance companies will try their hardest to wriggle out of paying

Other thing to consider is that sooner or later a test will be introduced to check that the DPF is present/working. In the meantime I read that MOT test centres have been told to fail cars where there's any sign of tampering to the DPF. Unlike with catalytic converters, cars with DPF's get lower tax so sooner or later the treasury will start leaning on dept of Transport to toughen up as they're potentially being cheated of cash!

I know all of the above is only if/buts/maybes but do you really want the hassle of refitting and re-mapping in a DPF.........

This environmental subject is way beyond people deleting dpfs... what about those that smoke and cause secondary smoking problems (grandmother died of this) what about those that drive ridiculously high engined cars, what about people that have no H&S regards to hazards like Asbestos and other respiratory problem materials, what about those that text and drive?

Off topic and somewhat irrelevant I know, but there is a bigger picture here (not having a dig btw)

Reading more into the subject (and taking advice from discussions here) it's put me off wanting to do this with my car.

As a great man once said, "The need of the many, outweigh the need of the few"...

Il be honest. Im a working man who doesn't particularly give two hoots. Lot of people harping on on this thread about the environment etc. You can't be that worried about the environment driving a V8 petrol car. Also has anyone thought what happens with the DPF's at the end of the car or units life? Most of those particulates are going to be released back into the atmosphere or buried in land fill slowly releasing their contents. What the hell do you think is happening when the DPF is going through its clean out cycle? Honest to god some people here are naive beyond belief. The only reason DPF's exist is to keep the masses in the cities happy via placebo and black faced free and to line the coffers of the treasury and local gov like the LEZ. If you think these little boxes on the back of your car are there to save the world or public health you need to be re-tuned to life in general. Rant over!

My advice would be to go for it, seriously are you going to kill anyone by having it done? To many by the bookers here!

We all speed, we all have used our phones when we shouldn't have and have most probably done worse things in life compared to taking a useless money pit of a box off the exhaust of a car.

Rebel!!!

i personally do not comment on the health side,i comment on the legal side,its ILLEGAL to remove the dpf so you will technically be driving without insurance,how would you feel if someone with no insurance hit you and possibly injured you maybe you would think differently then

Hence why you have your own insurance. Look I mean some people have to do what they can do to try and get by. Lots of neigh Sayers on these type of forums. I prefer to have a optimistic outlook on life! Lots of things I do are illegal, highly illegal in some countries, I don't loose any sleep, over it life's to short! Also the law (when it comes to the motorist) is an ****!

but if you delete the dpf then you have no insurance,and you also need to be aware that insurance companies do scan these forums,

After Reading everyone's Negative and positive comments regarding DPF Removal and Remapping, i have found a site where i can buy a new DPF for £280. All i need to do know is find someone to fit it, which I'm sure will cost a lot.

By the way, if people cant afford a new DPF for £1500 - £2500 from a main dealer, I sure people think about having the DPF removed and remapped.

Regarding Insurance, there are many people out there that mod their Vans and Cars, and never tell their insurance company, i have in the past.

brent i understand money is an issue but at the end of the day people are only advising against it for legal reasons,im sure i wouldnt like to be in an accident with someone that isnt legally covered,and as for claiming off your own insurance why should i.

I've never actually looked at one in person under the car but isn't it just a section of the exhaust? Could maybe bolt it in yourself, unless it's a single unit that goes within an original DPF section

i had a saab 9-3 estate and the dpf was directly under the manifold

In my experience if you void your insurance for modding etc. then the insurance will pay out the third party just not the policy holder.

Like when someone is drink driving, their insurance is invalid but the third party will still be paid out.

 

[whitenemesis]

And then the insurer will try and recover the money they paid out to the third party from the policy holder.

In terms of hardware, you'll need to fabricate a gas-tight length of exhaust pipe with the correct diameters and angles....

This is what it looks like:

So it is literally a bolt-on item?

Just to dispel a few of the myths in this thread.

DPF's trap the harmful particulates that would otherwise be released into the atmosphere. at intervals the DPF will be regenerated, this normally occurs at set mileages or sensed level of particulates in the filter. the regeneration nowadays is done by "setting fire" to the DPF and burning the Particulates all that remains is ash, at end of life service or failure there is likely to be only ash left in it or a small amount of particulate matter.

when regeneration occurs the DPF will reach some pretty high temperatures which is why they are always surrounded with a heat shield and normally close coupled (very near to the engine if possible).

The big thing with emissions and diesels was particulates, now that has been largely eliminated they are tightening up on other things like NOx...

oh and for all the folks who are comparing to petrol, get used to the idea as they will be fitted to petrol engines soon enough.

plenty of info out there.. read it..

Diesels illegally pumping out pollutants after garages remove filters designed to cut emissions

Air pollution from diesel particulates has been linked to 29,000 deaths a year


Many diesel VW cars are pumping out illegal toxins Getty Tens of thousands of diesel cars are illegally pumping out dangerous pollutants because unscrupulous garages have removed exhaust filters designed to cut emissions of deadly particulates.

Air pollution from diesel particulates has been linked to 29,000 deaths a year. Despite a government crackdown last year, backstreet garages and tuning shops are still advertising services to remove factory-fitted diesel particulate filters (DPFs) and reprogramme on-board computers to allow cars to be serviced more cheaply, deliver more power and trick emissions-testing equipment.

Diesel particulates enter the lungs and bloodstream; they have been shown to stunt children’s brains, and have been linked to autism, heart disease and cancer. Labour has joined air quality campaigners to accuse the Government of “negligence” over air quality regulation.

In the wake of the VW scandal – which centres on nitrogen oxides rather than particulates – testing authorities across Europe have been focusing on diesel engines. Last week, police in Spain raided eight garages in Madrid after a tip-off that they were removing DPFs and reprogramming software. However, in the UK, a legal loophole allows garages to remove the devices without fear of prosecution. An Independent on Sunday investigation has found that more than 1,000 garages, backstreet mechanics, and tuning firms are offering this service, often for as little as £250. It is only an offence to drive a car without a factory-fitted DPF.

The filter has been mandatory on any new diesel vehicle since 2009, but can become blocked after 80,000 miles and can cost up to £1,500 to replace. Last year, the Government introduced new rules so that a car should not pass its MOT if the filter has been removed; however, many garages reportedly fail to inform customers of this, while others openly boast that their work won’t be spotted during an MOT test.

“This will add to growing public concern about pollution from diesel cars, and the impact on air quality,” said Kerry McCarthy the Shadow Environment Secretary. “Air quality regulations exist to protect public health, but we are being let down by a negligent Government that is failing to enforce them.”

The revelation that thousands of drivers are still flouting the law by having their DPF removed and accompanying software altered has dismayed clean air campaigners. Simon Birkett, director of Clean Air in London, said the scale of DPF removal uncovered was “shocking”.

“Frankly, at least VW had a chip, even if it cheated during testing. Removing factory-fitted DPFs involves tricking or disengaging the whole emissions chip, all the time, on gases and particles,” he said.

Chris Roberts, managing director of Quantum Tuning, which provides DPF deletion-capable software to more than 280 garages and tuning firms, said garages were responding to “demand” from customers who “don’t have the money to spend on a £1,500 new filter for a car that might be worth £2,000”. He said: “Either they scrap the car or get something done about it. And if they are going to have it done, they may as well have it done properly by a garage that will explain what the MOT implications are, as our dealers do.” Mr Roberts said many customers viewed driving without a DPF as comparable to a minor speeding offence.

Campaigners say the MOT fails to catch DPF removal because it only includes a “visual inspection” of the hardware – which is often welded back together – and an “optical smoke test” which cannot detect dangerous particulate matter. A Department for Transport spokesman said: “If a car is fitted with a DPF and it is removed, it is illegal to be driven on the road. We continue to monitor how many vehicles are failing the MOT for this reason, and explore steps to stamp out this practice.”

Not sure why the sudden panic. Where do people think the diesel particulates were going in the 80 years before DPF's were invented. Just lots of knee jerk reaction from the General Public fuelled by media hype as always. I'm really sorry but the world has bigger fish to fry.
