How to troubleshoot coolant loss in a BMW engine?

I have noticed that my BMW engine is losing coolant, what could be causing this and what should I do to fix it?

One potential cause of coolant loss in a BMW engine could be a faulty radiator or radiator hose. Check for any leaks or cracks in these components and replace them if needed.

Another possible cause could be a blown head gasket. This can be diagnosed by checking for white smoke in the exhaust or a milky residue on the oil dipstick. If this is the case, it is important to have it fixed immediately to prevent further engine damage.
