Why is my Audi A4's engine making a rattling noise?

I noticed that my engine started making a strange rattling noise when I accelerate. It's a 2017 Audi A4 with about 50,000 miles on it. What could be causing this and how can I fix it?

It's possible that you have a loose or damaged part in your engine. I recommend bringing it to a certified mechanic as soon as possible to avoid any potential damage.

Have you recently changed your oil? Sometimes using the wrong type of oil can cause engine noise. Double check your owner's manual and make sure you're using the correct oil viscosity for your car.

It could also be a problem with your timing belt. If the belt is loose or worn out, it can cause rattling noises. You should have it checked and replaced if necessary.
