Why does my Audi A3's engine make a strange noise when starting?

I recently noticed that my Audi A3's engine makes a strange noise when I start it. It sounds similar to rattling or grinding, but it seems to go away after a few seconds. What could be causing this and how can I fix it?

This could be caused by a number of issues, including a failing starter motor or a damaged flywheel. It's best to bring your car to a trusted mechanic for a thorough inspection to determine the root cause.

One possible cause of this noise could be a loose or worn-out timing belt. If you haven't had your timing belt replaced recently, it's worth checking to see if it needs to be replaced.

Make sure to check your oil levels and quality as well. Low oil levels or dirty oil can cause strange noises in your engine. If your oil is due for a change, have it done as soon as possible to prevent further damage.
