Pinging when warm means it's running too lean. I know nothing about Jetta engines, but you can probably adjust your carbs for a richer mixture... a mixtue screw or re-jet them. Maybe post in watercooling section for more detailed answer.

more likely your comp ratio is up the shit ,,normally when manufactures increase capacity they increase stroke so by using a 2l stroke on 1.8 heads without relieving the combustion chamber you would have effectivly increased comp ratio about all you can do is run on premium gas and retard it a bit
