If you see the engine overheating light on the dash pull over immediately and turn the engine off.

My Ride: 2005 545i
sorry to revive an old thread but my dad's 545 is now overheating randomly & i was wondering if you can be of assistance 
my e90 (325i) was doing this as well. turns out it was an electric water pump failure. replaced that & thermostat & the car is fine now... was wondering if this is also a common problem on the 545i

If the engine is not overheating due to low coolant then the likely culprit is either the water pump or thermostat. Other items like a plugged radiator and inoperable electric fan are possible causes, but not nearly as common as the pump or thermostat. If you are sure the fan runs when it gets hot you can discount that.
Tell your Dad to do himself and his engine a favor and quit playing Russian roulette.
That is exactly what repeated overheating is for an aluminum BMW engine. All gaskets are stressed.
Replace the water pump, thermostat, coolant tank, vent tube, hoses and belts. If any of these components have been replaced in the last two years you can remove them from the list. It is not a bad DIY job if you are handy, but if you are not have the work done as soon as possible.
Stay away from the Beck & Arnley thermostat which is junk. I used this thermostat last year and it didn't last a week before the heater coil burned out. The OE Wahler unit is a good unit.
Mark the direction of rotation on the old belts before they are removed and keep them in the trunk as backups.

Thank you very much for the thorough response! The car has not been driven since the incident so I will definitely inform my dad. Thanks again!

I personally deal with random overheat messages. However, checking the temps using a PID capable code scanner and INPA, the temps always show normally. No temp related trouble codes. The overheat message will pop up and stay. I can pull the car over, pop the hood, slowly open the cap, and stick my finger in the coolant without much fanfare. Hot, but not overly so. 3 years and about 80K additional miles, it still does the same thing. Hoses changed, coolant drained, waterpump replaced, thermostat replaced, fan and temp switch ok...Center BMW thinks its a DME issue.

Did you determine that the car is actually overheating (if you raise the hood with the engine off a tremendous amount of heat will be given off in addition to clicking and popping as the aluminum components are over-expended)? You can also access the secret menu to get actual water temperature.
