Ok, update.
Went in first thing Monday, he had a call on Tuesday to say the clutch wasnt going to be covered under warranty again as it was worn not broken (so then why didnt they replace the 1st one under warranty that obviously wasnt worn but
was broken
), however the were going to replace the clutch master under warranty as it was leaking (a contributing factor?) as well as fitting a new starter under warranty as it was noisy & starting to struggle.
He got it back Tuesday night (quicker than normal from them, I`m wondering if they really did do the strip down & examination...) & they did the clutch at cost price as it was the 4th in under 50,000 miles (£430).
He got the old clutch back & said it is visably worn this time.
He`s now deciding whether he wants to risk getting more Fiats (maybe diesel or a 1.4 as the clutches should be stronger in theory) or whether to change brand entirely.
I have been looking out for upgraded/sports clutches for the 1.2 for him, but nothing so far.
