Hi Sashi,
I had 06 2.0 TFSI A3 and remember having to top up the engine oil every 3-4 months. The car only being a year old when I brought it and covered around 7k miles a year. As long as your car isn't consuming more than that I would say it's normal.
Creamy engine oil is a sign of water getting into the oil caused by gasket failure or moisture getting into the combustion chambers. Allow engine to warm up fully to stop the latter.
Hope this helps 👍
