Long ago someone found this on the web, and since then a lot of us use it and try to understand what's under our hood. This is the Study Guide that the Techs use to learn about the 2.7T engine, its systems, hardware, etc. It can be a great tool.

Its a small PDF so you can down load it to your computer and access it at any time.

Turbo Coolant is adressed in additon to Charge air routing. etc....

Happy New Year!
