I believe there are other threads on this issue, or at least on ones with a tapping noise. I have a 2017 C2S and on some days it taps for a while after startup and drive off. It actually can be a little embarrassing as I drive through the neighborhood. I'm having my dealer document it so I have a history of it happening this way iif anything were to happen after warranty they can't say I didn't report it.
A private off the record conversation with my Gold tech he said their tech forum it is a conversation and they are aware of it.

That tapping sound is normal and it is the DFI high pressure fuel injection nozzles. Only hear it in idle, then it is “drowned out” from exhaust engine sound (noise) 🤣! Enjoy the ride in good health!

Excellent. Thanks for the video. I was ok the fence about the AWE, but that sounds exactly like what I’m looking for. Do you get any drone on highway cruising? I’m assuming you have the HRE FF01 where too? Spacers on the wheels, they sit pretty flush? I’m guessing you’re lowered too? I like the entire setup a lot.

I actually narrowed down conditions for my "noise"; it is when the engine is cold, car is in drive (PDK) and idling at a stop with the foot on the brake. If you shift to neutral or park the noise goes away, same if you lift off of the brake pedal.
So perhaps it has to do with the transmission and something with the dual clutch mechanism instead of the engine?
Unfortunately, this makes it harder to capture a video as I need a second person to film or sit in the car with their foot on the brake, but I will try to get a recording this weekend.

stop agonizing about it. It’s completely normal. i’ve listened to the videos and upon cold startup and mine sounds exactly the same since new, 32k presently. Twice when she was in for service i asked different techs and both said, yup, very little sound deadening back there and its just normal cold 6 pot engine sounds. Embrace it.
