"Coolant! Visit Workshop!"

I get the "Coolant! Visit Workshop!" message pop up on the display every now and then. The car doesn't overheat at all. All of the levels are where they should be, including the washer fluid. I'm guessing it may be a sensor. Anyone know which sensor it may be and where it is located?

I am awaiting for the "this car will self-destruct in 5 minutes" message to come up sometime soon on the message board or complain about my driving style

I think either sensor gone bad or you need the Cooling System service which you need to do every 3 years. Keep us update.

most likely you're out of windshield wiper fluid. the sensors for the coolant and the windshield wiper fluid are on the same circuit.

Do you know what all is involved in the cooling system service?

That was the first thing a checked. They are both full. I think it gives you a different message for the levels though, something like "check coolant level" or something.

According to the flyer that I just got from MB of SD, it says

Cooling System Service (every 3 years)
Service includes pressure testing coolant system and cap, drain and refill system including engine block and heater core, replenish coolant with Mercedes-Benz approved antifreeze for 25 degrees below zero protection.

And the price it says here is from $79 but I dont know if the price will be the same at your dealer. Hope that helps and again keep us update.
