The warranty info I received from VW (you can find the same info on the vwcourtsettlement.com website) says on page 9 of 11 (in the pdf version it is page 12 of 14) "Conflicts concerning the warranty are to be resolved in favor of the consumer." If the Audi head honchos aren't cooperative, call the class action attorneys. Maybe go ahead and call them now, instead of waiting. Dealership already said no, it's time for the lawyers.
I would add that if VW/Audi took on the emissions repair in the first place and took credit towards their 85 percent completion, they should honor the warranty.
