VW (et all) passed the test - as prescribed by each government.
For politicians to take some sort of moral high ground is the greater insult.
They were insistent on "the letter of the agreement" on the expenses theft- but now are singing a different tune.
I'd happily (and preferentially) buy the original VW.

Al is right here! I don't know the exact wording of the law, but as I understand it, in Europe at least, a car must be capable of passing an audit, ie any vehicle could in theory be taken from the end of the production line and must pass the appropriate test.
Because the test is a known cycle the vehicle 'knows' it is being tested and uses a different software algorithm, and in some cases, makes more extensive use of emissions hardware to pass the test. After the test, or in normal use the vehicle reverts to the standard calibration.
This is a case of passing the test, but missing the point, but most probably would stand up in a court of law? This kind of thing has being going on for years, Volvo truck were caught doing this as far back as the late 80s. Most manufacturers (with the exception of BMW and JLR I think) have been suspiciously quiet.
VW could have said that their vehicles obey the law and pass the test, instead, when challenged in the US they rolled over, which I don't understand. They show have fought it, instead they admitted guilt with extreme haste?
