240d keeps overheating, replaced water pump, thermostat, bleed the system and the car is still overheating. I decided to remove the new t-stat and let it run freely with no resistance and the car still doing the same thing there's no coolant and oil mixture as an yet , does anybody dealt with this issue before.

 

You might try checking to see if you have an air bubble somewhere, and Forced is right... don't run without a thermostat
