Had a similar issue (Temp Gauge heading to red country fast from normal center location) this summer on my 2003 330i. Pulled over and looked, didn't see anything abnormal. Shut the engine off, Restarted and the temp gauge reset to normal.
A few days later, the same thing happened. Waited a while and then tried to restart. Same thing, as the gauge returned to the center. However, this time I was a bit more nervous & brought it straight (flashers turned on incase I needed to pull off the road immediately to avoid seizing the engine) to my mechanic who was only a mile away. The gauge never rose!
Bottom line was a crack in the overflow container. According to the mechanic, this was not "unheard of", in fact the local BMW dealer (source of his parts) seemed to be experiencing a run on the part as well. BTW- Never saw any leaks or stains on my driveway. Since then, nooooooooo more issues.

Thanks. I'll keep that in mind and monitor things close.
