It's not loud or nasty sounding. Just like and annoying little click? Worst of it is I've only noticed it now after the first time letting the Mrs drive it! It also asked me to press the start/stop button twice to stop which was weird?! Usually just press it once.
Can't help with the noise from the clutch, but it'll ask you to press the start/stop button twice to stop the engine if the card has been removed from the slot when the car is running.
If the card is in the slot when you press the button it will stop with just the one press.
I have that same click sound in clutch pedal as you described. Sometimes it clicks but not always. I have warranty from dealer until next autumn so i will sort it out later.
My cars a 56 reg so doubt it's covered under warranty. Done a Google search and apparently it can be related to some switch for the cruise control that's part of the pedal? Gonna get down n dirty in the footwell today and have a snoop about it see if I can see what's what! It definitely wasn't there before she drove it or when I was test driving. Always listening out for noises then.
