Gidday from the land Downunder I'm having exactly the same problem with my C5. I need to get a Veleo CL15 pulley to fix the alternator. All Citroen want to do here is sell me a new alternator at around $1800 AUD They say they can't supply the part, and Valeo in Australia can't or won't supply the pulley part either. Does any forum member know of any UK web site where I can order a Valeo Pulley for the alternator? Any assistance would be gratefully received Cheers Graham
