Hi, This looks like an old post but here goes. Is there a cross reference between Peugoet, Citroen and Fiat part numbers, given most of the parts are the same? My Relay has a lot of parts marked with numbers my Citroen dealer doesn't recognise, he's even checked the Peugeot database. But he can't access the Fiat DB to see if they are Fiat numbers. Thanks Chris
