Why is my Audi A6 making a loud noise while driving?

I have noticed that my Audi A6 is making a loud noise while driving, especially when I accelerate. What could be causing this and how can I fix it?

The loud noise could be coming from a worn out exhaust system. I would recommend taking your car to a mechanic to have it checked and potentially replaced.

Another possibility is that there is a problem with the wheel bearings. If they are worn out, they can cause a loud noise while driving. I suggest having a mechanic inspect your car to confirm.
