Car Manuals (Service/Repair manuals) are available from
This Erwin site works by charging a fee for access time, eg I bought 1 hour of access for 7 euros and was able to download all the service manuals (pdf) for my Touareg + the build sheet for my VIN. I was not able to find to owners manual on this site.
Alternately you can go to (Service/Repair and Owners Manuals)
These guys will sell you a PDF (~$70 US) which includes all of those service manuals able to be downloaded from the Erwin site above + includes a owners manual PDF and Build sheet for your VIN.
Just a point to note: The pdf owners manual is a bit rough about the edges
- It includes many hyperlinks to a VW site for additional reading which do not work.
- Some of the text is covered by the page header/footer
The owners manual is functional (just could be better)
and like
all things VW just because its in the manual does not mean your car has that option installed 
.
Having purchased the above I then spent considerable time and frustration with Acrobat Writer cleaning up 700 pages of the Owners manual and creating an index such that I could search it faster. (better but not perfect)
