Such rubbish reporting. I stop reading now the first time I hear it refereed to as a device. It's a program not a device. It's like VW cars are the only cars to have a Engine Control Unit (ECU) and that device cheated emission testing. Sorry I think near every car sold today would have an ECU so is every car sold today cheating emission?Quote:

To me changing the form of an emission into something that is not tested is just as much cheating as anything else. If you add more one end, you get more at the other.
Sorry but you have NFI what you are saying. For the sake of us all please step away from the keyboard and go and do some reading.Quote:

NOx is used because it groups NO and NO2.
This defies everything and I mean everything I have read and it has been a lot.Quote:

Happy Days.
interesting but useless
Nitric oxide is produced during thunderstorms due to the extreme heat of lightning,[5] and is caused by the splitting of nitrogen molecules. This can result in the production of acid rain, if nitric oxide forms compounds with the water molecules in precipitation.
Scientists Ott et al[6] estimated that each flash of lightning on average in the several mid-latitude and subtropical thunderstorms studied turned 7 kilograms (15.4 pounds) of nitrogen into chemically reactive NOx. Ott stated, ?In other words, you could drive a new car across the United States more than 50 times and still produce less than half as much NOx as an average lightning flash.?
^^ yep,it's no different to plug in electric vehicles,they just move the pollution from column A to column B.I'd like to know how much coal is burned compared to fuel to get two vehicles to travel 500k's. Pat
Wow that's a big call mate. I guess you are an expert on this subject.Quote:

I really don't understand that.:angel:
I guess this is why the media got such a run out of this.
We have guys like "frantic" making out like the world will end because his VW produces more than a standard. (yes I have followed you on VWWATERCOOLED forum as well).
And "isuzurover" who wants to debate what causes it. (I'm happy to learn and discuss but don't appreciate being told I know nothing).
And then "evo" and "PAT303" who I am with that this isn't really that big of a thing.
I think the standards are dodge. They are made by uninformed people. Just like I'm sure everyone has asked them selves more than once "Why are the council doing that, there was nothing wrong with it". The governments get it right more than 50% of the time and that what keeps the world moving forward but the rest just sells news papers.
Yes VW lied and they have admitted to that but i don't understand why the same question isn't being asked about all the other manufactures that also don't meet the standard. How are they doing it?
Yes VW NOx is high but are their other emissions lower and how much lower. Maybe their CO2 is so low the benefit will of set the extra little bit of NOx. Oh wait, that's not bad news so it wont sell a paper.
Hi All,
I can attest to the fact that the scandal has certainly hurt re-sale values of VW's - especially if yours was one of the naughty ones (mine was).
There is a class action under-way, with the legal firm taking 25% fees off whatever is won, with a "no win, no fee" clause..
The legal firm that I contacted was still interested in taking on my case with VW - even though I have now sold the car...
All I can say is - VW knowingly did something bad and they got caught. I have no doubt that there are many other companies, around the world, from all walks of life - also doing the dodge.. It's just that VW got caught.
As a former VW owner - my only gripe is that it hurt my back pocket when I sold the vehicle...
Yes I have wondered about the Steinbauer that was fitted to my Defender when I bought it. It makes that annoying noise when I turn it off so I assume the EGR is still working and cleaning itself.Quote:
