Coolant Type?

[CroftyOriginal]

I know this has been asked a million times but I have a 2017 S4 B9 and the coolant light comes on sometimes if its very cold out and only in the mornings so I am guessing its just a tad low but when I search what coolant to use, I get some many answers and none are the same so I was hoping someone on here could just tell me or even send me a link to the correct stuff. Thank you in advance.

Pop to your dealer if close & it's probably g13+ now, I always dilute it 50/50 as we're not in Saudi, that dilution is perfect & has worked for me in Italy & UK for many years & afaik B9 isnt much different.
