Topped up with Blue coolant.

[JRdrums]

I have a late 2019 MHT 520d. Checking the coolant level in the freezing weather it was sat on minimum so I added a small amount of genuine BMW blue coolant. My owners manual had no information on coolant type and typing my registration into a couple of parts supplier sites seemed to confirm the blue coolant. However It looks like my car will have green coolant in it. I feel like a dushbag having put the wrong stuff in. I only put a small amount in. Is it ok to mix blue into green? Many thanks

Genuine BMW coolant is G48 - but fine to use Comma G48

If you've only mixed a small amount it'll be fine; but are you sure the other stuff is green?

It is definitely green in the secondary coolant tank. Couldn’t really see in the main tank. Thanks for reply
