Well, the 2015 2.0L TDIs have an EPA/CARB approved fix.

If you assume that the 3.0L Gen 2 vehicles will need similar modifications, and it meets EPA/CARB standards, this is what it
might look like:
Part 1 -
An ECU flash that:
- Changes the sound of the vehicle
- Changes the cooling fan program that alters its sound and performance (louder, faster, slower, longer?)
- Changes the transmission programming in Sport Mode that makes it shift faster, and at a lower RPM
- Improves throttle response and shifting
- Increases in DEF usage from 1% to 14%
- Changes the high altitude transmission shift patterns that increase RPM
- Changes OBD (on board diagnostic) software that alters thresholds of malfunction detection parameters
Part 2 -
New/replacement hardware:
- A new DPF
- A new Oxidation Catalyst (if under 40K miles, you will get a 2nd replacement before 150K miles under warranty, if over 40K miles, you only get one)
- A new SCR Converter
- A second NOX sensor
- New labeling under hood
A new Emissions Warranty that covers hardware, turbos, entire fuel system, including HPFP, OBD system, and additional sensors.
Sounds like Sport Mode isn't Sport Mode anymore, even more CELs are going to pop with a more sensitive threshold setting, and the Oxidation Catalyst won't last more than 150K miles, just like the DPF.
If this becomes a fix for the 3.0L, they will be more of a "Maintenance Whore" than before. This reputation will filter over to the used car market, which already sees them as being less than reliable. Resale value will tank. I'm not sure who can think that fixed 3.0L's will increase in value? Just not going to happen.
