I can't find the few lists I found previously, Google search has become useless for that now that so many selling sites use these codes and that Google promote that kind of sites...

I found a list here, similar to one I found some time ago:
http://www.pagenstecher.de/Auto-Tuning-Technik-Talk/Auto-Technik---Antrieb/t120187p1/typ1--typ4.html
As you can see the Typ 1 actually had several sub-codes for newer models.
The Golf cabrio had a different code from the Golf, similar to the Beetle Cabrio.
For easier listing we simplified a little some codes.
