Related side question. A few months before this leaked out I bought a brand new Golf TDI(diesel) and I'm in California where it sounds like my car is technically now illegal? I have no idea what I should be doing at this point. I've been significantly overpaying on the note but not sure I should now. Does anyone have an idea what this means for the owners of the vehicles in question?
