Check Coolant Warning...but it's full
 
So on occasion I'm getting a check coolant warning message on my C230, but I've checked it multiple times.

It's practically full. I'm guessing it's a faulty sensor? Anyone have insight on this?


Also if it's as simple as that, is it easy to replace on your own?

Some 203's suffer this when the windscreen wash water container is MT.

Next time you have some time go out when ur car is cold like in the morning and pull the coolant cap off and start ur car turn the heat on hot and high and let it run till it reaches running temp then put the cap back on. You might have an air bubble in the Lines.
