bock,
you are making this harder than it should be. all oils have listed on the label somewhere which certification standards they meet. i'm not talking about a "reccomended for use in..." plug; i'm talking about the official certification standards part.
let me say this again: all oils which meet the vw certifications 505.01, 506.01 and 507.00 ARE APPROVED for use in vw's with pd engines (including your '06).
your manual is not the end-all-be-all of vw knowledge. remember, things change after printings sometimes. if you search in the fuels and lubricants forum, you will run across an official letter from vw that clearly states that oils with 505.01, 506.01 and 507.00 are suitable for use in vw's with pd engines.
i'm telling you, you're asking for trouble by putting your eggs in the dealership's basket. alot of the times, they have less knowledge than you do. and as far as manuals go, sometimes they have misprints. some manuals that came with early pd engine cars stated use of vw 505.00 oil, which was the wrong spec. anyone who had followed that advice and had had problems would have had warranty issues.
i'm not trying to be combative, but i suggest that you listen to some of the advice here. if you feel most comfortable getting oil from the dealership, that's fine. i would suggest that you make sure on the front end what you are getting b/c they often supply the wrong oil. just know, you do not HAVE to rely on the dealership for your oil/warranty needs.
