So, if the problem was the software, why they didn't fix it?

I have had trouble understanding the news reports about the Volkswagen
scandal. I have not found a clear technical description of what
happened. I think the reporters do not understand.
The gist of it is that when someone plugs a computer into the
automobile onboard computer, something changes. Press reports seem to
indicate that either the actual performance changes, or that the
onboard computer begins to generate fake data. It turns out to be the
former. When you disengage from the onboard computer, NOx emissions
increase to a level ~40 times above US allowed standards. Furthermore,
fixing this problem will probably degrade the performance or fuel
efficiency of the car.
Here is a short but clear explanation:

Zoom into the graphic box, "how Volkswagens defeat device works."
The article says they are thinking of installing a Urea injection
system to fix the problem. Piss on it, in other words. Bringing to
mind the saying, "If you was on fire I wouldn't bother to . . ."
The people at Volkswagen were unbelievably stupid thinking they could
get away with this indefinitely.
