Can any body advise if there are any online parts catalogues for the2011  Fiat 2.2 100hp, Have been advised that the fault is a seal rolling in either the slave cylinder or master cylinder, ( Its an external slave ) local car parts place have said go to Fiat and they want a fortune and on line they are approx 50% cheaper if I can get correct part no.
