VW Coolant leaves a "trail" when it leaks out... follow the trail to the source of the leak(s).

If no external leaks are found, then the coolant is being burnt in the cylinder(s) and air is getting into the cooling system / heater core
which would explain your cold air.

Bad water pumps will also cause no heat... but they also cause overheating.

Check for excessive coolant hose pressure... might need a head gasket.
