Welcome to the Forum

Good fun BMW's I have seen two types on 1 series engines 

1. A sealed unit BMW called it a "Heat Management Module" mounts above the water pump front of the engine. Just make sure you use the correct coolant when swapping them.

2. Similar unit same location but the Thermostat could be changed again correct coolant is important 

Your engine should be B38 to check the Thermostat location take a look at www.realoem.com put the last 7 digits of your Vin into the search box it will bring up your model then search the Engine section. The small exploded drawings will help with location and correct Part Numbers 

Good Luck

Before chucking more hard earned at it check carefully for any Inlet leaks all hoses and gaskets also Test the O2 sensors you can get Maf cleaners but be careful.
