If the car starts. Put a multimeter onto the battery terminals. You'll want to charge the battery a bit to do this test. Reason being: If the alternator is dead? The car will be running off the reserve from the battery.
Once the car starts, remove the jumpers and measure voltage. You should see about 14.5 volts dc. IF the alternator is doing it's job. (The battery and/or warning lights in the cluster should also be lit up like a christmas tree if the alternator fails.)
I honestly do not think Head Gasket at this time. Head gaskets tend to blow a lot of white smoke and most of the time the car can run (okay...run but badly)
I think what might have happened? Hose gets damaged and drains coolant on the alternator. (I hope the friend used G13 coolant..) The alternator might have been already on the way 'out' and the spill was the death blow. It could very well be internally shorted out causing quick drain of the battery. I would also urge having the battery checked for charge/load tested.
I'm still new at VW's myself, but that's my gut feeling. Others here have more understanding of these little 'buggers'. So we're all learning.
