Has anyone successfully installed a brake controller on a 2007 Q7 3.6 Prem? I have a trailer with electric brakes and I need to install a controller but I can not find any good tips or hints as to which one to install and how. I am reluctant to take it to a trailer shop without doing some homework.

 

If you have the tow package, the brake controller should be part of it. I had the same question & just called my dealer. He said the brake controller is integrated into the tow package.
