Thanks for your insight! The motor has about 48k on it, and it’s clean as a whistle!! The previous owner had the motor replaced under Audi warranty for oil consumption. I’m pretty sure the timing update was apart of the new motor as well. Never have any noise coming from it, it’s always running super smooth, that’s why I’m stumped. With my throttle body appearing to be clean and in all working order, I’m not too sure what to turn to next for the intermittent issue.
