Your 2021 Audi Q7 is going to have a smart wiring system. For the Curt Echo # C51180 to function properly and receive power you will need to connect your trailer 7-way to the Echo once you plug into the connector on your Audi. The computer in your Audi wants to see a full trailer connection before it will send power to the 12 volt circuit that powers the Echo. Your Audi will also have a trailer tow mode that should also be selected while you are towing.
