I'm still on the original radiator with no issues. But the coolant has always been topped off or replaced with BMW product whenever the cooling system was serviced.
Expansion tank is changed every 100,000 miles and hoses/coolant are replaced every 150,000 miles unless visual inspection during other service shows a need.
