Why is my Audi A4 making a strange noise when I start it?

I've noticed that when I start up my Audi A4, I hear a strange noise coming from the engine. It goes away after a few seconds, but I'm wondering if this is something I should be concerned about?

It's completely normal for your Audi A4 to make some noise when you first start it up, especially if it's been sitting for a while. This is just a sign that the oil is making its way through the engine, so as long as the noise goes away after a few seconds, you shouldn't have anything to worry about.
