G48 is a fine coolant - even Tesla uses it to keep their batteries cool. Mercedes is using G40 these days and dropped G05 a while ago. Both are SiHOATs, I think G05 adds on borate for wet liners.
Yes, G48 does have 2-EHA in it but the Europeans typically don’t have RTV silicone or PA66/GF33 gaskets seal cooling systems unlike GM and Toyota.
