Why does my Audi A5 engine make a loud knocking noise?

I recently noticed a loud knocking noise coming from my Audi A5 engine. It seems to be more prominent when the engine is cold, and it goes away after a few minutes of driving. What could be causing this issue and how can I fix it?

It is possible that your engine has a faulty piston or connecting rod, resulting in the loud knocking noise. We recommend taking your car to a trusted mechanic for a thorough inspection and potential repair.

Another common cause for knocking noises in Audi A5 engines is low oil pressure. Check your oil levels and add more if necessary. If the noise persists or the oil levels are fine, it may be a more serious issue and should be addressed by a professional.
