Rattle when switching car off

Usually the noise of your driveline coming to a stop when engine is turned off. Normal to hear on a TT6

 

Edit: You may also hear the IACV motors reset when engine is turned off. Sounds like a buzzing noise. This happens for a few seconds, so next time you start the car the IACV is able to give correct airflow into engine to allow start up & idle.

Put your foot on the clutch before you turn off, see if its still there or not

 

This plus at rolling speed in first if you lift and push the clutch pedal up and down to the bite point you may feel some 'lash' 'chatter/clunking' which is quite common.
