Why is my Audi's engine making weird noises?

I have a 2016 Audi A4 and I've noticed that the engine has been making strange noises recently. It's not a constant sound, but it happens when the car is idling or when I first start it up. I'm worried that there may be something wrong with my engine. What could be causing this and what should I do about it?

It sounds like your engine may be experiencing some sort of issue. It's best to take your car to a certified Audi mechanic to get it checked out. They will be able to diagnose the problem and recommend a solution.
