What can I do if my Audi A7's engine is making strange noises?

I have noticed that my Audi A7's engine is making some questionable noises. What could be causing this and what should I do about it? Thank you!

One possible cause of strange engine noises could be dirty or low oil. It's important to check your oil levels regularly and change it according to your car's maintenance schedule. It's also a good idea to have a mechanic inspect the engine for any potential issues.

Another potential cause could be a worn out or faulty spark plug. This can affect the engine's performance and lead to unusual noises. If you suspect this is the issue, it's best to take your car to a trusted mechanic for a diagnosis and replacement.
