Its actually the gearbox input shaft, and is by design. Shut the car down with clutch in. Thats how you stop it.

mine does the EXACT same thing.. in 1st gear when i ride the clutch a bit to start a stop sign or pull into parking it makes a grinding noise.. i guess is everyone's does it, it isnt to bad

also, if you give it some gas a bit above 1k rpm you wont get that rattle when letting off the clutch as bad.

here is a video of the rattle on turn off.

It is the dual mass setup and setup of the flywheel and pressure plate. If the clutch is depressed, it will make zero noise as others have already mentioned.

Its normal. The sound is a result of the motor being shut down or spun at a extremely low speed (normally experienced by stalling or engine shut down) where the inertial mass of the system is going in its intended direction, and once it comes to a stop, the internal springs of the dual mass "cocks back" and makes a rattle type of sound.
