Dead heater control valve. Hangs on the middle of the front of the firewall. Two ~1" coolant hoses and one electrical connector going to it. You can replace the core with a $30 Bosch part whose # I don't recall. BMW doesn't sell them except as a complete ($$) unit, but Benz, among others does. It's a drop-in part.
Biggest problem may be getting those four damn little screws out. The sage advice is, when you do, replace them with phillips heads or bolts.
