Check Engine Light and/or Engine Overheating on BMW 530i

Problem Description and Possible Solution

The thermostat may fail resulting in engine overheating and/or illumination of the Check Engine Light. Replacement of the thermostat along with a complete inspection of the cooling system will be necessary to correct this concern.

Overheating can cause severe engine damage. If the engine begins to overheat it is recommended to stop at the first available location and have your vehicle towed to a repair shop.

3 times in 24 hrs my car indicated that it was overheating. Don't know y? What should I do?
Overheated on I-5. Pulled over and waited to cool. Started again and had same issue. Towed back to home base. BMW dealer diagnosed water pump and replaced it and thermostat. $1600
Engine overheating display then it said stop vehicle turn off engine.
Very sensitive aluminum engines in most of bmw cars. Bad head cylinder leaks oil that mixes with the water causing the engine to heat. U need a new head cylinder and sometimes u might need to change the whole engine
Service engine light. Says engine is hot to pull over now
I was driving my bimmer normally down a semi busy road and when I looked at my engine temp. it was all the way up on the red! I began pulling over and as I was I heard a huge pop noise come from the engine, immediately after that white steam/smoke began pouring from under the hood. I turned off the car instantly put it in park and popped the hood. Within about 10 seconds the steam/smoke was gone. As soon as I got out of the car a man who was smoking a cigarette outside of Mcdonald's ran up to me telling me that he has the same car and the same thing happened to him. He told me I didn't want to hear what he had to tell me, it was the head gasket. So right after that I closed the hood and we got a few other people help us push the car into the parking lot. I called a tow truck and they came within 60 min I had them tow it to a mechanic by my house that is trustworthy.
