Why is the engine of my Audi A8 making strange noises?

I just noticed that my Audi A8's engine is making some strange noises. What could be causing this issue and what steps should I take to address it?

It's possible that there could be a problem with one of the engine components, such as the belts or bearings. I would recommend taking your car to a mechanic for a thorough inspection and diagnostic test.

Another common cause of strange engine noises is low or dirty oil. Make sure to check the oil level and quality, and replace it if needed.

Have you recently changed your car's air filter? A clogged air filter can also lead to strange engine noises. Consider replacing it if necessary.
