Add some 50/50 mix of bmw coolant to top off and another 10-15 mins for the coolant bleed procedure and no leaks!

is it a common problem on those n55?
if yes, bmw are kidding or what? this issue is there forever ! still not fixed? |
These thing tend to fail on every bmw it looks like. It's a good measure of just replacing it if you can.
