As alleged in the NOV, VW manufactured and installed software in the electronic control module of these vehicles that senses when the vehicle is being tested for compliance with EPA emissions standards. When the vehicle senses that it is undergoing a federal emissions test procedure, it operates in a low NOx “temperature conditioning” mode. Under that mode, the vehicle meets emission standards. At exactly one second after the completion of the initial phases of the standard test procedure, the vehicle immediately changes a number of operating parameters that increase NOx emissions and indicates in the software that it is transitioning to “normal mode,” where emissions of NOx increase up to nine times the EPA standard, depending on the vehicle and type of driving conditions. In other tests where the vehicle does not experience driving conditions similar to the start of the federal test procedure, the emissions are higher from the start, consistent with “normal mode.”

I have not read a substantive response from any part of VW to today's allegations.

There was a good This American Life episode recently [1] that walked through a few different alternatives for how VW could respond to this whole scandal. The host solicited feedback from 3 different marketing firms:

One firm, run by the guy who saved Jack In The Box with the ubiquitous sphere-head Jack commercials after an E. Coli outbreak killed 4 kids, said that VW should run an ad of a new executive blowing up the boardroom to symbolize changing the old guard.

Another firm suggested they crowdsource answers to how they can fix the problem/make it up to the public.

The last firm said they should just shut up and not draw attention to themselves. They're not in a good position to say anything right now, and they should just let the collective public forget about it and move onto the next scandal.

I'm assuming the third options is what VW's retainer-ed marketing firm has opted for.

Mercedes-Benz was in a similar position in 1997 when the newly introduced A-Class flunked the moose test. After a short period of denial they hired a specialist (Armin Töpfer), halted production for several months and retooled all cars with a different suspension and ESP. The ESP wasn't even necessary but put competitors under pressure to include it in their compact class cars as well. The crisis was eventually overcome and the car sold very well in Europe (1.1 million produced in 7 years). There's a fascinating book (sadly in German only) on this called "Die A-Klasse: Elchtest, Krisenmanagement, Kommunikationsstrategie." (http://www.amazon.com/dp/3472037997)

Notice the different 3.0 litre engine affected.

Yes and this new NOV as well as the excerpt I highlighted from yesterday applies to those engines. Essentially EPA has evidence of a defeat device on the 3L now too.
