Hey all. I've got a Jan 2020 C300 Coupe, and tonight I got a yellow coolant warning on the digital dash. Let the car cool and took the cap off the expansion tank. There's definitely coolant in there, but I'm not sure I'm reading the level right. The lower part of the tank is white, the top is black. In the lower part is two raised lines that form a T-shape. I think that is the level guide? It's above that, but it might not be 1.5 cm above when warm so maybe it just needs a small topup.
It does seem like there is a smell coolant when the engine bay is warm, unless it's just warm new plastics. It's a newish car, but it has done 7k miles so it's not exactly brand new. Can't see any sign of leaks though, it all looks fine.
