Why is my Audi A4 making a rattling noise under the hood?

I have noticed that my Audi A4 is making a rattling noise under the hood whenever I accelerate or decelerate. It seems to be coming from the engine area. What could be causing this and how can I fix it?

The rattling noise could be caused by a loose heat shield or exhaust components. I recommend taking your Audi to a mechanic to have it inspected and repaired if necessary.

Check your oil levels and make sure they are at the recommended level. Low oil levels can sometimes cause a rattling noise in the engine.
