Stop Car Keep Engine Running
So, we have a 2018 C300 and live in Maryland. Just got the car CPO in October. Didn’t drive the car for 1 1/2 weeks, not real cold. Got this message this morning. So let it run for a bit. Then ran to a few place and the message never came back on
Do I have a problem or did it just sit too long?

A gaggle of MB's
That "message" can be common - you have a "main battery" which is the genuine battery you are used to - then there is a "auxiliary battery" which is actually a capacitor that holds a charge that then provides juice to the essential systems of your Mercedes to keep those systems "alive" when the engine is turned off.
The message comes up when re-starting your Mercedes - which started fine (right?) - and tells you that "auxiliary battery/capacitor" has run down a bit and needs to get topped back up full by your MB running.
