BMW ETK question

[Mike]

I recently obtained a 2-cd ETK off ebay containing the TIS and ETK cd's. However, someone told me that there is a 5 cd set availble. What is contained on the 3 remaining cds, and where can I purchase it (couldn't find it on ebay). Thanx for your replies.

The other 3 that I have have got good wiring diagrams and some other dealer software that I can't figure out what it does.

The latest ETK that I have is 2 CDs by itself.

is there a "how-to"-type procedural cd?
