Hi All,


This morning the check coolant level warning came up and went away probably within 1 minute of starting (cold start first thing in the morning, restart after coffee stop did not yield it and no stored warning). I live in MA and the temps have shifted significantly the last week or so (MUCH colder), other than that nothing has changed in the last week with the car.


I will obviously continue to monitor this and check back, but wanted to see where this may lead and if anyone else has experienced this.


Car is a 2013 E550 with ~45k miles.


Thanks in advance!
Brian

low coolant because of significantly colder tempretures.
might wanna check your fluid and maybe top off a lil

Silly question, but did you check your coolant level?

sleeperZ96BT

Yeah, looked ok and didn't come back after yesterdays message. Wonder if it was simply a sensor hiccup.

NOPE
later on when it gets cold itll pop up again , itll be here and there untill you add some distilled water or actual coolant , because that means coolant as a minumum level and as it gets colder..............

Yeah, I'm going to check it cold cold cold in the morning tomorrow. If it reads full I will take it to the dealer. It came back on today (3 degrees at 6am) and stuck a bit longer than usual so you may be right.

I too experienced this issue. Coolant level looked good.
After a couple incidents, I added a small amount and problem went away.

Check your windshield washer fluid. The sensors are tied together and low washer fluid can trigger the coolant warning. Really.

Well, I added a small amount this weekend and no warning today, so, I guess even though it was full it needed just that little top off for some reason.
