Why is my Audi engine rattling?

I recently noticed a rattling noise coming from my Audi's engine. It seems to happen more when the car is cold. What could be causing this and what should I do?

It's possible that your engine has a loose or damaged heat shield. This can often be the cause of engine rattling when the car is cold. I would suggest bringing your car to a trusted mechanic to have it checked out.

Another potential culprit could be a lack of proper lubrication in your engine. Make sure to check and change your oil regularly to prevent any excessive engine noise. It's also a good idea to have your car's oil pressure checked to make sure it's at the correct level.
