Why does my Audi's engine make ticking noises when it's first started?

Every time I start my Audi A4, there's a noticeable ticking noise coming from the engine. Is this normal or should I be concerned?

This ticking sound is likely just your engine's hydraulic valve lifters adjusting to the cold oil in the engine. It's a common issue in many vehicles and is nothing to be worried about. However, if the noise persists for more than a few minutes, it's worth having a mechanic take a look.
