That presented a quandary. A larger tank would rob space needed for the luxury sound system. But a smaller tank would require more frequent refills, an inconvenience that Audi feared would deter buyers. So the cars were designed to ration AdBlue — and pollute more than allowed — unless software in the car detected the telltale signs of an emissions test."

Does that sound correct per the settlement?

Since Florida doesn't have emission testing someone could dump water into the DEF tank and just fool whatever measures the level sensor. If the article is correct and the fix is so easy I doubt VW is going to pay for any extension, so forget about a buyback. What's aggravating is that its taken so long for this fiasco to be settled.
