Only in America
They didn't do so in Germany or many other countries, though.
Here, they pretended to fix the problem with a plastic piece for a few cents and software updates. Recent tests have shown that they didn't fix anything. The emissions seemingly (just about) made it, but then they sored up during cold temperatures (winter) instead = hoax).
So, over here the cars lost A LOT in value and their owners didn't get zilt from Volkswagen. ;-)
