Ugly tapping noise

Broken water pump impeller? Hope so. Anti freeze would boil and leak out somewhere. If no oil mixed in spill, probably a simple w/pump replace. Been there couple of times, in Boxster and Volvo.

I thought a flashing temp light meant low coolant level?

Check coolant level. And check under your carpet in the rear trunk for coolant.

Flashing temp light means HOT. Coolant level could be fine. Radiators need unobstructed ventilation and coolant flow, thermostat OK? belt turning w/pump, engine cooling fans operating. etc...
