I keep picturing some engineer browbeaten by his boss to make sure the next engine passes the emissions tests or he's out of a job. So that's what he does, makes it pass the test. And the code is so complicated no one is catching it.
No way. This was a well known issue amongst diesel people to get the emissions down.
Here's a story on the Ceo:
Excellent story here. Good overview.
“Technically, manipulating emissions values is relatively easy,” said Amin Velji, a researcher on emissions at the Karlsruhe Institute of Technology. “But it’s not legal, of course.” Mr. Velji was surprised by the revelations that VW had installed a so-called “defeat device” to reduce nitrogen oxide emissions while its cars were undergoing testing.
He said modern diesel technology was basically clean, provided that the right methods were in filtering emissions.
Two VW models failed the ICCT test for two completely different reasons. In the VW Passat, the nitrogen oxide is filtered out of the emissions with a system that injects a urea-based solution. The ICCT suspects that VW had reduced the amount of urea injected to spare its customers having to refill the urea tanks themselves.
With the Jetta, the second VW model in the ICCT test, VW uses a nitrogen oxide reservoir catalytic converter that stores the oxide particles before they are released. But this system has to regenerate itself. The bigger it is, the faster it can do so, but the more fuel it consumes. The ICCT believes that in the Jetta, the reservoir system fitted was kept small to keep fuel consumption low. As a result, especially on long journeys at high speeds, the cars emitted nitrogen oxide unchecked. That kind of construction flaw is hard to fix in a recall.
Still, the researchers at ICCT don’t think all diesel systems are flawed. “Diesel can be very clean,” said ICCT Managing Director Peter Mock. That was evident from the tests of other manufacturers’ cars, including German automaker BMW, which had performed very well both in the lab and on the road, he said.
Only two weeks ago, the ICCT had analyzed data provided by the ADAC General German Automobile Club on 32 vehicles tested on German roads. “The technology works if you apply it properly,” said Mr. Mock. It depends on how much manufacturers are prepared to invest — the filtration systems for modern diesel engines are expensive.
The ICCT found major divergences between lab and road test results in Europe, too.
European tests are still conducted under laboratory conditions and more realistic testing methods won’t be introduced until 2017. For VW, it’s crucial that the scandal doesn’t damage confidence in diesel technology in Europe.
This opinion piece from that same German financial paper. Can't access the whole thing though.

Over decades, the auto industry successfully crafted an image of itself that looked like this: cars are technically brilliant, a feast for the eyes, they’re sublimely comfortable, stir deep emotion and create millions of jobs. Especially if they’re made in Germany. BMW, Daimler and Volkswagen are simply the best.
VW has shattered this picture. The new image looks more like this: cars stink, they pollute the environment, endanger people’s health — and the German automaker Volkswagen is a huge fraudster.
The scandal over rigged diesel emissions in the United States has hit VW with devastating force. It has obliterated billions of euros of market value within hours, wrecked consumer confidence in the brand and tarnished the credibility of a company that wanted to lead the world.
