Welcome Alan

First when you say "no heat" I assume you are referring to in the car ? Some checks I would make are (1) is the coolant level correct and no leaks (2) can you adjust the fan speed inside the car (3) check all fuses 

In the engine bay is a coolant valve (normally passenger side inner wing) if these fail no flow to the heater, also if the FSR (Final Stage Resistor) fails you will have no heat in the cabin plus no fan. both are fiddly not difficult to change. the sender may be the culprit for the gauge not working.

Try looking at www.realoem put in the last 7 digits of your Vin in the search box it will bring up your model and all the part numbers, also check www.newtis.info a BMW repair shop information site you will get repair/replacement information there.

Hope this helps
