Tyrant: I don't feel RBs post read that way.

It almost sounds as if you may have another issue like a bad fan clutch, wpump, tstat. Maybe the coolant is not circulating properly. These BMWs have there own way of running hot. Probably as Josh said you may be burning a tad of coolant at different times. My car has an OK head gasket but it drips on the outside and not through the internals. If you are losing coolant you may want to check the heater hose connections on the drivers side. 3 of them goes thru the engine bay to the foot well above the accelerator pedal behind the carpet/steering wheel. I am fixing one now - it sux because of the carpet.

Here is a link to help you understand and test your system. It is all in the Bentley but this is the best write-up I found to understand how the coolant circulates.
And NAPA also sells an additive you can add to coolant and use a blacklight to search for leaks.
