Question:

I have a 2008 VW Touareg 2 with factory hitch. I connect the 4 wire trailer harness to the 7 pin factory. Everything works except the brake lights . Turn signals work on the right circuits - I checked each bulb individually. I also get a warning in the dash to check brake lights so the car is recognizing the problem. What could be the issue? Thanks.
