Audi A4 engine noise

I recently purchased a new Audi A4 and have noticed a strange noise coming from the engine. It only occurs when I start the car and lasts for about 10 seconds before going away. Should I be concerned?

Yes, you should definitely have it checked out by a mechanic.

It's probably just some engine break-in noise, but it's always better to be safe than sorry.

I had a similar issue with my Audi A4, turns out it was just a loose belt. Have a mechanic take a look to be sure.
