In my sig there is a link to A google doc/spreadsheet "Our Q7s" When opened, at the bottom of your screen you will see a list of other sheets. One of them also contains a DIY section. Scroll down that sheet, you will find a brief description of the item and possibly model year and also a link back to the thread or post usually with pics. You have to click into the cell then click the url which appears.
It sounds long but over time you will see its a much faster way of finding the stuff you want.
The spreadsheet is open so anyone can add more info or download it for their personal use. (HINT: use list mode to filter without affecting others)
All info contained there has already been posted on the forum!

Here's the retrofit of the hitch and brake controller.

I did not retrofit the oil cooling system.
