The 2.0 was near the minimum-mark when I bought it so put in half a litre in August. Check oil level came onto the dash the other day so put in another half litre. Was going to check but always forget as I live on a hill!Had my A6 C7 3.0 TDI for almost 2 years/15K and not put any oil in yet (a waste of the 2 litres of oil I bought!). It did have an oil change 5K ago but prior to that it was only a fraction off full on the oil level display.
