Help my e90 335i is acting up

sorry this will be long but i want you guys to be aware of all the symptoms. So this is for a 335i n54 engine. I posted earlier last week that the car fan was super loud and now it is on almost all the time the a/c started blowing warm air every time the fan went full blast also the car loses power when try to speed up (kick down) and once the "engine too hot" warning came up , everyone here including me thought it was the water pump/thermostat although it has been changed a year ago. So when we took the car to the shop today these were the codes. Even the shop said it was unusual and had to look it up and call tomorrow. So i am hoping somebody here would have an idea.

It seems that the thermostat or water pump are failing, always replace both at the same time, but first go online and check the codes so you're sure of what you doing, for me the fan spins loudly, heated and It loses power, sounds like a thermostat and water pump. A year ago checks if you still have warranty.
