Apart from the color, the coolant level in the 2 reservoirs seems to be significantly higher than what I have noticed in mine. Did you ever top up coolant/ added extra?

@EQBFan I did add coolant. I was annoyed with the sound of trickling coolant in the cold early morning from what I believe was air in the system. So I employed an old aquarium draining technique and filled the levels above that of those three awkwardly high coolant lines towards the front of the “engine bay”. I also noted the “trick” to the service advisor when I brought it in for its 11k mi first service, and the tech topped them both off the exact same way. I actually do not hear that meadow brook sound (which I believe was air) any longer. Sadly something happened and the coolant in just that one side has become opaque.

I asked the SA to have the 12 V checked as I got a pre-safe type error after charging a second time, as I suspect a weak 12 V…

My EQB just came after its first service. Coolant level was a little lower than the max indicated on the reservoir but the dealer did not feel the need to top up the coolant.

I do have a can of coolant lying with me that I got from Amazon. Can someone confirm if this is the appropriate coolant? Also, in 2 minds whether I should top up the coolant. Any suggestions?

I'm used to the old MB standard of blue, but I checked and pink seems to be what they are using in modern cars. And yes, fill it up to the full line. In the future if you need to check what product to use, check the back of the owners manual under specifications.

What still has me confused is whether the EQB comes under "Smart Electric Drive" or "All other model series" in their specifications for Operating fluids. Funnily no EV models are listed there.

I know it is confusing, but if you zero in on the 320 sheet, it still says to use 326. Because these cars are so new and people haven't had time to dump in the wrong stuff, you can be pretty confident between the operating fluid spec sheet and common sense of matching color that you are okay.
