Just spoken to my other half..
& i got it wrong,
the 107 has only done 16k & was last main dealer serviced at 12k,
the AA man has now turned up, & is checking it out.
I concurr, at 16k even a wear plate is not fit for purpose.
If its a machanical failure then it should certainly be warranty work.
Will do a search on Miklad's link
Peugeot will only class a clutch as warranty UNDER 20k miles. Believe me - I know.
Do a search for Miklad and read all about it mate.
Anything over 20k miles and its classed as 'wear and tear'.
Now if your car had a Toyota badge on the bonnet, it'd be covered up to 60k miles.
s***e isn't it?

Sorry to be the barer of bad news.
