Hesitation when blipping throttle

Ok, just got the Z4M roadster home and with all used car purchases there is a bit of newbie car nerves. So all seems good, no rattles or bumps and the car drives well, but just a couple of questions to the wise?

1) it could be me but when flooring it (when warmed up) I swear I felt a slight hesitation..... But only once. This could just be the Vanos working as we were from 3000 rpm, but anyone else occasionally feel this. It was not missing or anything and was very slight.
2) when hot and idling, if you quickly stab at the throttle to blip it, will it stutter/ revs momentarily drop befor picking up? Only when idling and if more gentle no effect is seem

3) when turning it off, as the engine stoops there are perhaps the briefest second of some big rattle/clatter. That sounds melodramatic but it is not ment to be, I seem to remember my E36 m doing something similar.

Done a throttle reset just in case, but any reasuring "don't worry newbie" comments? Like I say just first drive nerves.
 
The hesitation in 2 above is a well known thing. Fixes seem to vary. Some have had throttle position sensors cleaned or replaced, others have just done the throttle reset and it fixed it.

Mine was starting to do it, the dealer reset everything and updated all the software and it's fine now.

the rattle on switching off is the springs in the clutch , try putting the clutch pedal down while you switch off to confirm this, :thumbsup: just getting used to the normal moises is a bit stressful at first, but you will soon find your way around a great car, enjoy and btw , welcome :driving:
