Why does my Audi A3 engine make a knocking noise at low speeds?

I recently purchased a 2018 Audi A3 and have noticed a knocking sound when driving at low speeds. It seems to go away at higher speeds. Any idea what could be causing this? How can I fix it?

There are a few potential causes for this knocking noise. It could be due to an issue with the engine's timing, fuel octane level, or spark plugs. It's best to have a certified mechanic take a look to properly diagnose and fix the issue.
