It all boils down to a combination of factors; not being run in properly from new and high mileage will take its tow. Most 1.8t will be loading oil through the valve stem seals and piston rings, my engine was using about 250ml every 400-500 miles and was on 150k. Upon removing the intake manifold there were signs of failing valve stem seals and this was the state of my piston before I cleaned it:

And of course the cylinder wall were glazed


After


There were signs of excessive wear on the piston rings and oil rings - all of which contribute to using oil! There was a slight drop in compression across all 4 cylinders and it's clear from the above photos this is expected.
Even the valve guides were caked in oil residue.
