Expert Reply:

Sometimes the emulators just aren't as reliable as they should be on newer vehicles. It's very possible your vehicle has to sense more of an amperage draw on the trailer wiring circuits to allow them to be active. I'd try connecting to a trailer first and go from there as it's very likely your trailer wiring is fine on your 2019 Audi Q7. In general German vehicles have more issues like this than other manufacturers.
