Why is my Audi A8 making a loud noise when I accelerate?

I recently purchased an Audi A8 and have noticed that when I accelerate, the engine makes a loud noise that doesn't sound quite right. I'm worried that there may be something wrong with my car. Could you please provide some insights on what could be causing this issue and how I can address it?

This could be a sign of a problem with your exhaust system. I suggest taking your car to a trusted mechanic to have it checked out.

It's possible that your air intake system is clogged, causing the engine noise. Try cleaning or replacing the air filter and see if that helps.

I had a similar issue with my Audi A8 and it turned out to be a loose belt. Have a technician check the tension of your belts to see if that's the cause.
