coolant temp gauge acted up.

I was driving yesterday (90F weather) with AC half way blasted and I noticed that when I got stuck in a little traffik, my temp gauge went to RED and lighted up for a few seconds. So I kept my eye on it for a while and it went back down slowly on its own. I finally got to my destination and popped the hood. Nothing seem to indicate any overheating since I did not smell anything burning or extreme underhood heat. I drove around a little more keeping an eye if it returns but never did. Anyone had this happen to them? thanks - Rod

You need to replace your thermostat most likely....

If you press for time, just flush the radiator $24 + $1.99 (BMW coolant + distilled water) and maybe 1 hour of labor. You may have some crud in the coolant floating around clogging the thermostat from time to time.
