I have a TDI but I am in a no-test state (FL) and I am strongly debating keeping mine. My question to you is about the airbag from Takata, which you say will not be replaced (If I understand your posting!) Where is the source of your information?
My understanding is that the owner has the option of taking the buy-back (car will be trashed) or keeping the car and getting a cash payment. As I understand the legalities, if I keep the car, the Takata airbag will be replaced at no cost to me under the entirely separate Takata recall.
Spoke to VW. There is no fix for the Takata airbag and they are not doing much about it. They are waiting for Takata and Takata is not doing much. Essentially they told me that there is not a fix, when there is a fix the southern states will bet it first, and they have no idea whether this will happen.
