2019 GLC63s Coolant Smell
We've had a coolant smell after driving the vehicle. This has been happening since we bought the car 2 years ago. I can't see no leaks. The coolant level stays constant. Any ideas what this can be?

‘18 GLC63
Interested in this as well. My ‘18 sometimes has a coolant smell as well. 32K miles, no leaks of any kind.

With turbo engines, you have two separate coolant systems...make sure you check the coolant levels for BOTH systems. They are exclusive of each other and do not share coolant!
