The previous owner had great records so I looked them up and the same issue happened only 11k miles ago and he had the t stat. Water pump and thermostat and all gaskets and vent screws changed at the BMW dealership where he bought it. Now I am stumped as to what this may be. Any ideas???
This here to me sounds like a t-stat. If your water pump failed you would have hot on both hoses. At least for me that happen when the Bosch pump failed. I would recommend that you replace t-stay and fully bleed your cooling system and try it.
