[Vwdiesel] Well, I guess this confirms it, internal head gasket leak

[James Hansen]

Definitive test for combustion chamber leak into the coolant is with 
test paper strips.  You can get them at your local engine builder, 
tractor supply house, farmer kind of stuff- acklands etc, not flap 
sources and the like. THey test for fizz in the coolant- carbonic acid.
