I see (2) coolant reservoir or expansion tanks what ever you want to call it. Is both of these tanks are on the same circuit and connected on the same system or is this is a 2 different system? The reason I ask is I saw both tank low on coolant and I did get the warning low coolant message.

I did top it off in both tanks with the pink color (MB Part number BQ-1-03-0005)
