How do you know wiring is good? It sounds like it is not good.
you have tried two different trailer modules
you have tried two different trailers
I would put a test light on the 7-way trailer connector and if lights still don't work, put a test light on the plug inside the back of the X5? If you have the trailer module connected correctly, you should get brake and turn signals at the connector inside the X5..
