Why does my Audi A6 have a knocking sound when I accelerate?

I have noticed a knocking sound coming from my Audi A6 whenever I accelerate. It seems to be coming from the engine. What could be causing this and what steps should I take to fix it?

Hi Maxine, the knocking sound could be caused by a few different things. It could be a problem with your engine's timing, a loose engine mount, or even a worn-out serpentine belt. It's best to have a mechanic take a look at your car to diagnose the issue and recommend the best course of action.
