Help understand BMW codes
 

I just checked my codes history and found a few codes that are not current but happened recently. I've tried to search for what they could mean but got nothing. If anyone has any explanations on them please help. I've attached 2 screenshots. I know that 2EF4 is a thermostat code, but I've already changed it twice now so could it mean something else?

edit: My car is 2006 BMW 530I N52 engine with 117500 kms (73500 miles)

also: The main problem I'm having is engine runs too cool at 75-80C and takes a while to warm up, Since I've already changed my thermostat twice, radiator, 2 temperature sensors, coolant multiple flushes, I don't know what else it could be. Hopefully some of these codes might point me in the right direction
