funny how they test them when they are new and then people go blank the erg valve, because it just gets clogged up and put a straight pipe on. i wonder how much NO my car puts out.
I'll tell you when I stop coughing.
Volkswagen cheats emissions tests!

Apart from those buyers with any kind of conscience who werent aware quite how bad the NOx is on diesels. They will probably buy petrol, and will probably buy non VW. This revelation has increased the awareness of the issues considerably.
It would be obvious to most buyers that VW are a hugely successful company. If they were to go into administration then another company would simply buy them. It's not like they are Rover and can't compete.
I expect Porsche would be first in line to put an offer in!
Although to be fair it isn't only VW finances that are being hit, VAG shares as a whole are suffering at the moment.

I may be wrong, but I thought NOX was part of the euro standard, and much stricter unde euro6?
This is an interested to piece about how VW were caught, and also suggests than BMW are clean (apologies if it's a repost)

Fingers crossed for a massive tax resulting in an influx of people switching back to petrol!
VW is the parent company of Porsche.
I'm ahead of the trend, my petrol VW (165 CO2) should be with me in 5 weeksFingers crossed for a massive tax resulting in an influx of people switching back to petrol!

I doubt they are the only manufacturer to do something like this.

Don
I thought it was more complicated than that, with VW owning the Porsche car manufacturing (Porsche AG), but with the Porsche Holding Company (Porsche SE) owning a substantial share in VW?

Also appears to now be known as "Emissiongate"
I do think that it's possible they could have similar software controls in place across all their engines including petrol for various purposes. For example maybe they have software to detect when the car may be on a test drive which then increases performance at the cost of much higher emissions. Once a workaround is in place for one function then there would be a real temptation to find similar uses for it.
I would also be surprised if other manufacturers don't do something similar even if it's not to the same extent.

Yeah.
Porsche Automobil Holding SE is the parent company of VW, Porsche Engineering and Porsche Design. VW in turn is the parent company of Porsche AG and all the other companies.
I think it was because Porsche AG had a lot of debt so this restructuring was the best way of financing the takeover/merger.

Barring BMW in my experience, no other car gets near their mpg figures so i would not be surprised.

Well its what makes a car legal to sell or not. If it doesnt meet EU6 then you may end up with a car that has to be returned and purchased back by VW. As i understand in the states the non compliant cars can not be resold by provate buyers either... so you're kinda stuck with it until a clear process has been decided.
All US vehicles must be issued with a certificate of conformity that proves they adhere to environmental standards.
To obtain a certificate of conformity, a manufacturer must submit a list of all auxiliary emission control devices (AECDs) present on the vehicle. The EPA’s definition of an AECD is “any element of design which senses temperature, vehicle speed, engine RPM, transmission gear, manifold vacuum or any other parameter for the purpose of activating, modulating, delaying or deactivating the operation of any part of the emission control system.”
The issue facing Volkswagen is the switchable system in the ECM was not declared.

You would if you drove the same cycle....

This whole urea thing... Can't they just put a hole in the side of the car for the owners to pee in to fill it up?

And only did it on a rolling road with no actual movement of the car.

Well actually you would under the same conditions.
The problem is with 'devices' started with similar tests where the if the bonnet was open the engine calibration would run differently and hence you would get different results.
Of course the problem with NEDC is that is for all vehicles including trucks, hence slow acceleration rates that no one does in a car in the real world. Thats different to actually having the car engine operate differently if the bonnet up, or, i dunno..... maybe a period of no steering angle change detected....
US has a weird thing where emissions related components are expect to last 150k miles aswell. Hence things like Hybrid powertrains and BMW high pressure fuel pumps getting extended warrenties. The Honda IMA batterys even extended to 157k to cover Odometer inaccuracy to ensure the customer got 150k of real miles.

There are various problems with NEDC but mostly they amount to it being totally unrepresentative for real-world use. The lack of anything to represent cruising at medium to high speed is a fairly obvious one. Trucks do that too.
Now you say that trucks have to do it. Doesn't the extra urban component briefly go up to 75 mph? What happens to vehicles that are limited to less than that?
