It is acceptable to use 1ltr per 1000ks with your engine and VAG have that as a disclaimer in the handbook and they have stood by this for years, i started with them in 1988 and it was the case then. What 2.0 litre is it? reason i ask is that the Beetle 2.0 was shocking for drinking oil. Got to the stage i would check the oil if a car was in for a headlight fault or something, just made it a habit.
