This is a very helpful video. People with m54 with heater problem could have replaced heater core valve, tried to flush heater core, or even replaced the electronic controller for the HCV and still not heating enough. Thank you for posting. I wonder if this same 2-piece hose connection exist on e46 or e83 or just one single hose from engine block to firewall.
Ya this is only for the 6 cylinder engine x5. In this video he is not working on the v8 so don’t get your self confused
The reason for this is damge to cooling system? Any leakage ? Or?
Someone put stop leak on thair system .

Something to consider ... Great info Thanks for sharing!
Can you flush this out without replacing the set of hoses?
