car over heating with a P0597 DTC

I have an 06 325i, over heated last night, pulled over immediately. Looked around and seen no leaks other than the little bit that pushed out of the reservoir, immediately thought the electric water pump went out on me but got it to my shop and was able to hook up my hand held scanner to find the P0597, but my shops computer doesn't have the euro package (I know its lame) and not sure if I should put a tstat in it or water pump, the fact that the code is an open circuit I would think it wouldn't allow the car to over heat... any suggestions?

Wow, Google works so well. How does it do that?
Either way, for you I would suggest changing both the tstat and water pump at the same time. They are bolted together and depending on the mileage or last time the pump was changed, it may be gone a few days after a tstat change only.

open circuit means the the "electrical" circuit is open meaning infinity ohms. It doesn't mean the cooling circuit is open. Whatever has an open circuit needs replaced assuming there is not a broken wire or a disconnected connector. Also, how did you test the pump?

I know what open circuit means but usually if it defaults into open circuit it keep the thermostat open to prevent overheating, in some cases. And I I opened the resevoir and let it run, then seen circulation and it actually streaming coolant, so I'm sure the pump is working.
