I tested again tonight and it's now working like it should.
I wish I had an electronic copy of the owners manual. Those are available on the US website, but not the Canada website. My vin unfortunately doesn't work on the US site either
edit:
I just went and searched new Z4 for sale ads. Some have the US VIN. So I used that to get access on the US site. There's way more owner information on the US site than the Canada site. I downloaded a pdf manual.
