Why does my Audi A1 engine make a ticking noise on cold starts?

I've noticed that when I start my Audi A1 after it has been parked for a while, the engine makes a ticking noise for the first few seconds. Is this something I should be concerned about?

The ticking noise is likely due to the engine oil being thick and cold on start-up. It is a normal occurrence and should go away after a few seconds. However, if the noise persists or gets louder, it may indicate a more serious issue and should be checked by a mechanic.
