The problem, CARB says, is that VW's proposed fix is "too vague," according to USA Today. The EPA agreed with CARB's take, saying that the plan to fix the larger Volkswagen, Audi, and Porsche vehicles was incomplete. CARB's letter read, in part:
VW says this is all part of the process to once again make its diesels clean and that it will continue to work with regulators to find a fix. There are only 16,000 of these larger diesels in California and 85,000 across the country. Overall, almost half a million VW Group diesels are affected in the US.
VW's and Audi's submissions are incomplete, substantially deficient and fall far short of meeting the legal requirements to return those vehicles to the claimed certified configuration.
