Talking to an Audi rep, and Diesels in the US

OK, dumb question time.

I've heard this part of the explanation before... but it begs the
question "what happens when you put high-sulfer diesel fuel in a
modern TDI engine that wants to drink low-sulfer fuel?"

If the answer is "it kills the engine in 25 miles", then we're back to
the chicken-and-egg scenario.  If the answer is "you get lower mileage
and maybe 10% shorter lifetime of engine components"... then maybe it
behooves the car manufacturers to start importing the new TDI engines,
just to get the ball rolling.

Maybe this is what Audi is considering?  (I've heard rumors that they
will be importing some of their TDIs... supported somewhat by Mr.
Duane's anecdote).  Or maybe some parts of the country (CA?) are
startign to get better diesel fuel.
