Am I mistaken to think the Mk2 Scirocco (esp those with A/C) has hot 
coolant flowing through the heater core and uses a flap to divert air 
through it or not depending on the control lever. Oh, that was a question.

Well, if that is the case the you sir have 'my lever is unhooked' type 
problem. If not, and you can pop the hood to verify, have someone work 
the lever and verify if 1) you have a valve & 2) it closes all the way.

There is AIR then there is A/C, these two systems overlap. Even with the 
compressor removed the other parts of it are trying their best to 
comply. You can see this in #2 s you describe when A/C is selected all 
of a sudden a closed flap is opened and the air flows. (Plus the idle is 
adjusted thinking the now missing compressor is going to induce drag.)

So, your basic problem is flaps and lack of control, lever like. 
(Anybody want to confirm or deny whether vacuum has anything to do with it?)
