2.7t engine design and function
 

i came across this self-study pdf. file on the biturbo engine. if you're a DIYer it might help you learn a little more on your project. you can find it at: http://www.allroadfaq.com/downloads/...ne_english.pdf

hope it helps someone. :)

Thanks that a very cool document. Some of the same information and pictures is available in the Bentley manual.

No can you find a similar document for the ZF transmission?

yea the Bentley manual is great but it's like 100 bucks or something. i've been looking for similar things for the ZF transmission but no luck so far. i'll definitely post anything i find tho.

The Bentley manual is probably worth the money if you plan on doing your own repairs. I paid $63.97 for mine new from Amazon.com.
