Please excuse my ignorance, how many Gens are there in the CR 2.0? I thought the engines were roughly the same 09-15. Just putting on my bean counter hat with my engineering background, there is no way they are making a fix. How long have we been promised an AWD TDI, since like 2012. VW has no intention of playing the diesel game in the US Market.
The stated goal was to have 85% buyback. That leaves roughly 75k cars left that need to be fixed. It's not a simple software fix, the DPF barely makes 100k miles when run intermittently, imagine cycling it more? If there was a simple urea fix they would have announced it by now, or at least hinted at it (much like they forever tease gorgeous European stuff we can't have over here).
So for 75k cars that you have already sold, you need to invest the engineering resources to find a compliant exhaust system, while the EPA has a colonoscope in you, and you just forked over $10B to clear the deck of the rest of these cars? Never gonna happen. What is the ROI on that.
I would like to keep my TDI, fix or not, but if you can't come up with a HPFP or other exotic parts 5 years from now, is the car really worth anything. I would expect a statement in spring 2018 that after 'countless' hours of engineering expense, VW is unable to satisfy the EPA on the 09-15 TDI's, and that they will no longer support a diesel platform in the US Market. I know they promised a '17 TDI, it is probably in the same shipping container as my '13 AWD Sportwagen.
