BMW X1 35i help overheating!!

[DriverX1fast]

Please help Any advice I’m lost at this point. I own a 2015 BMW X1 XDRIVE35I. The car about 3 weeks ago driving popped up “overheating-yellow-” following “stop engine now overheating-red-“ no acceleration when this is happening! When and once it’s happening no heat either! So follow up about a week ago I replaced the water pump and thermostat everything’s running great then yesterday out of no where started happening again at a light out in town! No leaks I did a pressure test as well everythings good has coolant. Now it won’t bleed but you can hear the water pump kick on, the heat is blowing lukewarm now also I believe there is too much air in the system I have no idea how to get it out with the bleeder system not working. Any advice??:

I'd go to professional mechanic myself.
