Water Pump
Hi all.
Having some issues with my N52 powered 2006 E87 130i race car. It appears that the water pump is not functioning correctly. Below is a brief run down of what I have done so far:
I tested the factory wiring at the pump, and it appears to be getting all the right signals. It recently came from the dyno where the tuner told me it was all working fine including the fan. I'm at a complete loss here. I am really hoping someone will be able to shed some light on the situation. People tell me to just put an aftermarket pump and everything in it, but at this stage I think that is just bypassing a problem and not addressing it. Any help would be greatly appreciated

Not sure if this helps or under what conditions you see 220F but 100C or 212F is normal operating temp. for my car when cruising at a steady speed. 105C is not that unusual under those conditions. Temp. drops to about 85C when I'm pushing, then returns to 100C+ when I back off to cruise. I monitor this with an AccuGauge permanently connected to the OBD.

Just an update on all this. Apologies for not previously replying.
It seems that I was simply not allowing the car to run hot enough before assuming there was a problem. Olgeezer1 was correct, and 220F+ is normal for the car at idle or very minimal load. I pushed my nerve a little more and brought the temperature up even further and low-and-behold, the fans and pump kicked in and down the temp came. Last month at the circuit, the car ran faultlessly in the temperature department. Thanks to all those who offered assistance/thoughts.
