Mysterious coolant leak on drivers side control arms
I literally looked everywhere and even thought for sure it’s the turbo coolant lines but from what I can see and even doing a pressure test, it’s completely dry by the turbos. Leak is coming from the drivers side motor mount area and leaking on the control arms and it’s a pretty steady drip. Any input? 2015 E63

Do a pressure test on the engine coolant circuit and charge cooler.
With that much leakage, should be easy to find.

Isn't there a hydraulic bushing?
