2017 x15 Coolant system pressure test. Not losing pressure after 20 minutes ??

There is a DEF doser test in Insite. I unbolted mine from the pipe and let it hang by the hoses and ran the test. That way I could confirm that was where my trouble was for my problem. When the doser is working right it pulses a spray like a mist out of it.
