I think this happened to me last night.

driving in heavy suburb traffic. Had my a/c on for defrost.

Got a yellow water temp light. I got a little nervous as it is 29 degrees out and I'm not in the best neighborhood.

Turned off the a/c, opened the windows and cranked the vent to high.

Noticed I had very little power in the engine, but no 1/2 power symbol.

THEN BING RED TEMP WARNING and then no power. Pulled over and turned the car off. Opened the hood. Couldn't smell anything really. I've had cars that have overheated and this wasn't it.

Called BMW Assist. They told me to call the Roadside Assistance.

Let it sit for a few minutes. Started right up, no warnings, nothing.

Drove it in some clean cold air...No problems.
Drove it to a friends and let it idle for 15 minutes...No problems.
Turned it off and let it sit for 6 hours and then drove home an hour...no problems
Drove to work this morning...no problems.

My GF and I were gonna take an overnight trip to Chicago last night, but the weather concern made us change our minds. That would've sucked.

Water pump/Thermo???

called SA this morning and waiting for a call back
