Leaking coolant from pipe below expansion reservoir
My S550 w221 has been leaking coolant from a pipe located under my expansion reservoir. The pipe runs into the wheel well of the car on the passenger side. So far it only happens when I park the car after a drive but does not happen everytime. I have also noticed the heater does not seem to blow hot unless I turn it up past 80 degrees now. Not sure what the problem is or where to start, any help or guidance is much appreciated!!

I don't have leaking coolant, but have noticed that I need to set my heating temperature very high in order to heat the cabin. In any other car I've ever had, setting it at 71 +/- is fine. In this car though, I need to set it at 78 or so to keep warm. Anyone else have this issue? Not sure if it is an issue, or just a quirk of the car.

Its been replaced a year ago
my reservoir is only about a year old the leak isn’t coming from my reservoir it’s coming from a pipe that’s leading through the wheel well of the passenger side of my car and there is a hose connected to what looks like an aluminum tube that runs into the well of the car tire and that is where it’s leaking from
