What can cause engine rattling in an Audi A5?

I recently purchased a used Audi A5 and have noticed a rattling sound coming from the engine. It only happens occasionally and goes away after a few minutes of driving. What could be causing this and should I be concerned?

Engine rattling can be caused by a number of factors, such as low oil levels, a faulty timing chain, or worn out engine mounts.

To diagnose the issue, it would be best to take your Audi to a trusted mechanic who can inspect the engine and pinpoint the source of the rattling. It's always better to be safe than sorry when it comes to your car's engine.
