Why is my Audi A8 making a strange noise while driving?

I recently purchased a used Audi A8 and I've noticed a strange noise coming from the engine while driving. It's not very loud, but it's definitely noticeable. What could be causing this and how can I fix it?

It's possible that the noise is coming from worn out engine mounts. This is a common issue with older Audi A8 models. I suggest taking your car to a mechanic and having them inspect the engine mounts.

Another possibility is that there is an issue with the transmission. I recommend taking your car to a certified Audi mechanic and having them perform a diagnostic test to determine the root cause of the noise.
