Volkswagen/Audi "Standardized" Measuring Block Groups for Gasoline Engines.

Use as a general guide for engines starting about 1999-2000, where more specific data is not available is not available for a particular Group.

Note:  Quick and dirty formatting of the following pages appears to be incompatible with some browser.   I really hate to do this, but I strongly suggest using IE or Mozilla to view these pages.  If someone would like to grab these pages and reformat them so that they look decent with more generic browsers, I would appreciate it and would be happy to repost more compatible versions.
