Check Coolant Level Message
Yesterday morning, when starting my car, the following message was presented:
Check Coolant Level.
See Operator's Manual
I checked the manual, and it says:
Have the coolant checked or refilled only at a qualified specialist workshop.
So, I had Mercedes Roadside Assistance tow it back to Wexford. Hopefully, it is simply a loose hose. I told them that the system will need pressure checked, and the oil must be inspected to ensure there is no coolant in it.
The car has 120 miles on it, picked it up on Monday. ( I'll post images of the car after it gets the ppf applied.)
I'll post the details here for the record.

For the record, here is what they found:
The coolant line from the ISG had failed at the fitting near the engine. This was a case of infant mortality failure of the line.

The line was cracked at the fitting. Since the failure happened at so early in it's lifetime, it's not very important exactly why or how it failed. Any component can fail upon initial failure. It is a case of infant mortality.
Once a component serves it's first couple hundred hours, it should last for thousands of service hours until it wears out. I am sure MB will review the warrenty report and evaluate.

This is the "Bathtub Curve" of mechanical component failure rates. (image taken from Wikipedia)
My coolant line failure would be plotted on the red curve just below the E in "Early".
