DPF Removal
Now to be an MOT failure.... DOT Press Release
Not sure how they will check - if internals removed then it will look superficially OK, but a finger in the tail pipe will reveal all.

There's going to be a lot of cheap C5 2.2s around. .

Re: DPF Removal
I wonder if we will see companies moving from the 'FAP removal and re-mapping' business into the 'FAP re-fitting' business?

Re: DPF Removal
The term will be DPF repair services . The hollow sound from a tapped DPF will be the only way it can fail, so new "heat shields will need to be made, don't worry, there will be plenty of ways around it.

Re: DPF Removal
Maybe I would think differently if I owned a diesel and was faced with an expensive DPF replacement, but I've always felt that removing a DPF is a bit of a selfish and short sighted activity - save money but to hell with the environment or peoples health. Maybe it wasn't against the letter of the law until now, but it was certainly against the spirit of the law.
The particulate soot from a non DPF diesel is a particularly noxious pollutant IMHO especially for those with conditions like asthma, and it makes me cringe when I see someone foot down in an old diesel with clouds of soot coming out the tail pipe.
Modern injection petrol engines with 3 way CAT's have exhaust emissions when running correctly that are so clean and free of HC and CO that you could almost breathe them without fear of consequences, a far cry from the CATless carbureted petrol engines of a few decades ago which could kill you from CO poisoning in under an hour of idling in an enclosed garage...
I hate the replacement price of a CAT but I for one am glad of the improvement in air quality that mandatory CAT's and testing of them provides, and its about time that diesels were held to the same standard of emissions performance as petrols...
I shall now don my flame resistant suit and retreat to a safe vantage point

Re: DPF Removal
If the DPF has been removed completely and a non DPF exhaust section added I wonder how the MOT tester is going to tell if the car originally had a DPF ?
Maybe by going off the VIN number...that's some data base to keep...the dealers sometimes don't know if the car has a DPF from the VIN...
Cheers

Re: DPF Removal
Year of manufacture most likely as legislation requires the fitment of various bits and bobs from a certain date.

Some cars of the same model, year & engine type have them while others don't.

Re: DPF Removal
No flaming from me, I fully agree with you. One of the main reasons I bought my current 'X7' C5 was the FAP system it is fitted with. I only wish that we could currently afford to replace my wife's non FAP equipped car with something more up to date: the amount of rubbish that it produces is astonishing compared to my car, and if started up in a garage will have you immediately gasping for air. And this for a car that sails in under the legal limits for emissions!Mandrake wrote:Maybe I would think differently if I owned a diesel and was faced with an expensive DPF replacement, but I've always felt that removing a DPF is a bit of a selfish and short sighted activity - save money but to hell with the environment or peoples health...The particulate soot from a non DPF diesel is a particularly noxious pollutant IMHO especially for those with conditions like asthma, and it makes me cringe when I see someone foot down in an old diesel with clouds of soot coming out the tail pipe...

Re: DPF Removal

Re: DPF Removal
My own mistake I bought C5 R with FAP, however I only do short journeys most of the time, so Regularly goes into limp mode. I thrash down the local bypass in limp in 4th that tends to sort it out.
I was going to remove it but I suppose now I had better not, I could really do without re-fitting it and reloading original MAP.
All ums and arrs.

Re: DPF Removal
It's all very well driving around with a DPF & and an imaginary halo over your head, simple facts of the matter are that they do not work in this country, with our traffic conditions and flippant vehicle use.
How much pollution and fossil fuel usage do you think is caused by people having to "blast it down a dual carriageway", just to keep the car working, or garages doing forced regeneration so to "clear" the dpf.
Personally I think diesels are dead if the emissions regulations are to get much tougher.
All this "green " legislation is total bull$hit anyway! there are plenty of worse pollutants than the cars driving around Europe, guess it's ok so long as the sky above us is ok.

Re: DPF Removal
Couldn't agree with all that more. If you have ever done a forced regen on a car you will know how bad this is, you can practically see the fuel gauge dropping as it does it, all the emissions you have prevented in the last thousand miles has just gone out the window when you either have to force a regen or blast it down the motorway.Lighty wrote:It's all very well driving around with a DPF & and an imaginary halo over your head, simple facts of the matter are that they do not work in this country, with our traffic conditions and flippant vehicle use.
