This didn't blow up a year and a half ago because VW had not yet confessed. The timeline as I know it is that these results were published a year and a half ago, which got the attention of the EPA. The EPA did their homework, and about a year ago, started pressing VW on this issue. VW denied for a year, and just recently finally admitted. It's an unfortunate timeline, but I think a reasonable one.

And great insights on the software side of this.
- jazzyk 11y agoEPA doing their homework is fine, but what exactly is reasonable in VW denying this for a year?
- scott_s 11y agoNothing. I'm assuming that VW is in the wrong and not reasonable. I interpreted the original question to mean, why did every one else (media, government, public) not pay attention to this until now? Given the timeline, it's reasonable that the media, government and public did pay attention when they did.
- kale 11y agoHere is the letter (PDF copy) that was sent from the EPA to VW, VW America, and Audi. It was sent last Friday, which is when the story "broke". The initial investigation 18 months ago kicked off an investigation by the EPA. VW denied any wrongdoing but admitted to a "glitch" and started issuing ECU updates. This is why some people think there is already an ECU fix for this out there. There is a "fix" from last year that says it's an ECU upgrade for emissions, but it was a stalling tactic / red herring while VW continued to cover up the extent of the deception. http://www3.epa.gov/otaq/cert/documents/vw-nov-caa-09-18-15.pdf http://www3.epa.gov/otaq/cert/documents/vw-nov-caa-09-18-15....
