We have an 05 golf tdi and occaisonally run b20 when we can find it.  We had
to do no mod in order to run it.  Just fill er up and go off guilt free.
One major problem in doing this however, VWoA will not honor any fuel system
warranties if anything higher then b5 is used in their cars.  I found this
out and that kind of worries me a little if i have fuel pump or something
fuel related go out in the next few years, i am out of that cash with no
warranty to back it up.  VW may change their stance on the b5 vs b20 issue
as technology improves.

As far as the bumper sticker, we have a lot of drivers in our area that have
those plastered on their cars as well.  It does create good awareness of
being environmentally sound, but i feel that if you have to advertise
anything like that you are just looking for people to notice you not what
you do, "I am a good person, right?".  if you know you are doing the right
thing and feel good about it, you don't have to advertise it.  my $.02.
