Start by filling coolant with the proper coolant. Make sure all air is out. Double check after you run the vehicle for a bit. Then check again the next morning. There maybe cylinder head damage from this if it got to hot. There are lots of possibilities on the initial failure causing the overheating.
Start by filling it up.

SOURCE: can an empty coolant reservoir tank cause the temp

Yes! If the coolant level drops below the temperature sensor the steam that is generating in the system will cause the gauge to read incorrectly.

Testimonial: "thank you! After the oil change, I added some 50/50 coolant to the reservoir, drove it around in the same conditions &the gauge stayed where it should"

SOURCE: the mile omiter and clock dont show up on the dash

If nothing is broken, check to see your dash light dimmer isn't turned all the way down. If you have automatic lights that turn on at dusk and you place something over the light sensor (usually on the dash board), the headlights will come on during the day and set the dash lights to the dimmer switch setting.

I have a 2002 325i BMW with 85K miles. It's had temp gauge problems for quite a while but until recently had no signs of real overheating. (I drive her only rarely though).The gauge would stay...

To verify if cooling system damage exists.
Drain the engine coolant.
Remove the intake manifold.
Remove the plastic heater core feed pipe.(located under the intake manifold).
If the coolant pipe cannot be removed after removing securing hardware, the VANOS banjo bolt must also be removed thus allowing additional clearance needed to remove the pipe.
Visually inspect the front (inside) of the coolant pipe.
If the plastic on the inside of the coolant pipe shows no signs of deterioration (smooth surface) the engine should be reassembled using new gaskets and O rings where necessary.
If the plastic on the inside of the coolant pipe shows signs of deteriorated (worn away, bubbling, ect) this is an indication that the engine has been severely overheated and these components must be replaced.....Cylinder head gasket,all coolant hoses,all plastic coolant pipes,coolant expansion tank and cap, radiator, water pump, thermostat, oil and filter....

Hope this is some help to you ??

Loud rattle from engine and overheating

I wonder why the overheating caused you to change the engine instead of checking with the cooling system. Some time back my 323i overheated and coolant expansion tank burst open, but that probably due to ignoring the coolant level low light for a couple of days. I replaced the coolant expansion tank, thermostat and few hoses connected with the tank and it worked fine for me.
Try to check you coolant level - may be you should have replaced your water pump and not the engine.

Sounds like a cylinder head problem. If the coolant is boiling over into the bottle, but not leaking anywhere, that the engine is using its own pressure to move the coolant. There could be a cracked valve guide or just a blown cyl head gasket. Have a mechanic/or friend test the cylinder pressures with a gauge and this should tell your where the problem is and what the next step should be.
