From other post

BMW Blue is the ideal. Short of that, any coolant that is Green or Blue is the same idea as BMW. Mercedes spec coolant would be my next choice. These guys have similar requriements for additives that are not harmful to aluminum/plastics used.

Any DEXCOOL intended coolant is bad - Orange in Color ( at least here in the US ). General Motors was involved in Dexcool, and the biggest issue for Orange Coolant, is it makes a mud like substance when mixed with the Green/Blue stuff.

Pink is the Japanese spec mix ( Toyota, Nissan, etc ). I would also avoid that stuff.

Hope this helps.

Go with either BMW Coolant or G48 ie blue coolant or G05 (Yellow or gold) and don't worry about it. Originally they came with G05 (ie YELLOW or GOLD) same as G48 with nitrates and not extended life (ie 50k vs 150k miles). What ever you choose make sure you flush the system before switching over, and never mix coolants, no matter how compatible it is.

Noticed you are in UK also. I use ready mixed G48 from Halfords and never had a problem. As the others have said, it is crucial to flush the coolant out first and put in the new fresh one in.

Valvoline's green Zerex G-05 is a perfect substitute for BMW's own blue coolant. I've long since lost all the information I had saved, but it was determined to be chemically all but identical. It's all I've used since day one and I've had zero issues. As mentioned, make sure to flush, and avoid mixing wherever possible. Personally, here in Australia I've never been able to find the gold bottle version of Zerex
