Why does my Audi R8 engine make a knocking noise?

I've noticed a knocking noise coming from my Audi R8's engine. It's not consistent, but it seems to happen more often when the car is idling. What could be causing this?

This could be a sign of worn engine components, such as the piston or connecting rod bearings. I recommend taking your car to a trusted mechanic for a thorough inspection.

It's possible that your engine is low on oil or the oil needs to be changed. Make sure to check your oil levels and schedule regular oil changes to prevent potential engine issues.

Have you recently filled up your tank with low-quality gasoline? This can cause knocking sounds in the engine. Try filling your tank with a higher octane gasoline to see if the problem persists.
