Opinions or Experiences of Auto Box in 2005 Audi A4

[Hark]

3.0 tdi manual

Ad says 6 speed tiptronic.

What's it like to live with and any major known faults that make it worth avoiding over a manual?

Welcome your experiences.

Does the auto knock it in to a new tax bracket?

Got the price list as a pdf if you want it...
Think the tax is unaffected because it was registered before 23/3/2006.
