Why does my Audi A5's engine make a strange ticking noise?

I recently bought an Audi A5 and I noticed that the engine makes a strange ticking noise when I start the car. It seems to go away after a few minutes, but it's still concerning. What could be causing this and should I be worried?

It's possible that the ticking noise is coming from the valves in your engine. This is a common issue in Audi cars and can be resolved by taking your vehicle to a trusted mechanic for a valve adjustment.
