It's likely that the knocking noise is caused by low oil levels in your engine. Make sure to check your oil levels and top them up if needed.

There could be an issue with the spark plugs or ignition system. It's best to get your Audi checked by a professional mechanic to diagnose and fix the problem.

If the knocking noise only occurs when you start the engine, there may be an issue with the fuel octane rating. Switch to a higher octane fuel and see if the noise goes away.
