Did anyone notice the 'ports' in the non-flywheel end of the piston
barrel area of the block ?

one is exposed when the water pump is removed..
the other is cover with a coolant pipe/flange.

Use some extraction device through those holes.
Mandatory to heat the piston some .....
  not 'tons' ..just some, with oxy-accetylene torch.

'Clever' of VW to make it so you have to use your extraction tool for
both piston pins through that one hole..
( subaru has a hole on each si, fore and aft,  conveniently in their
opposed 4 engines )

People have used threaded rod .
there are exanadable internal grabber tools .( like to grab and extract
a oil pressure relief piston say )

A good machine shop that does whole engine rebuilds should have some of
those extractor tools.
