It sounds like you're trying to install a standard 4-pole on your vehicle. To add a 4-pole to the factory 7-way on your 2013 Audi Q7, you can use the Hopkins Plug-In Simple Wiring Harness, part # 41155. This will connect into your 7-way and give you the 4-pole you need.

I've linked to a video installation of this harness on a 2018 Dodge Durango so you can see how it works.

However, if you have a 4-way round on your trailer, then you can use two adapters to get it to hook up to your 7-way (one on the trailer and one on your vehicle). On your trailer's 4-way round, you need to convert it into a 4-pole flat using part # ADP001. Then, on your vehicle, plug in part # 47345 into your factory 7-way. The two points should then connect as a 4-pole flat connection. I've linked to video reviews of both of these adapters.
