S500 coolant problem
Mercedes W223 S500 4matic
The car is showing low coolant level even after top up. There has been a coolant leak only when the car is parked overnight. We have checked for leaks but couldnt find anything. Even checked through pressure sensors for a leak. But no idea.
Anyone who has experienced similar issues?

I smell a lot of coolant after shutdown on my car. While I haven’t seen a coolant warning yet, I also don’t drive it very much, less than 4k miles a year. I also haven’t seen any puddles below my car. Any semi-educated person would say that something is leaking and by George, they’re probably right.
