I had pretty much the same problem with my TT and a Ford F250. Turns out the problem was with the 7 pin connector on the truck. After having the brake controller checked, the brake wires completely re-done, I swapped out the connector and everything worked. I got a new connector from etrailer.com.
This is a thought I had too. The contacts in the truck's connector aren't corroded, but definitely dirty and were full of dust. There is a cleaner tool but is expensive and probably cheaper to just replace the connector. All the lights on the back of the TT work great though.
There's also some connector blocks at the rear bumper near the connector. Not sure if they're related to the 7-pin connector but also another possibility.
Your 2012 is about the age when my 2003 Chev had trouble with the bumper 7-pin. It comes in two parts unlike the standard replacement ones you buy. Between the two parts was all corroded.
Replacing it with the standard one- piece took some effort because of the weird wire colours Chev uses. There is a diagram for that on the web somewhere--try Google. Also "mirror images" to figure out for which way the pins "face" with the two halves of the OEM plug going to the replacement.
The new one did not go on the OEM bracket so I have it strapped on the bracket in an ugly way.
