2003 C3 Hdi, 70,000 miles. The engine has finally stopped after months of occasional/intermittent cutting out. It would cut out for about two seconds whilst driving and restart straight away, and always before any momentum was lost. Tonight it cut out again but won't start. The battery is strong, the cambelt is intact and there are no unusual noises. No obvious pattern either, sometimes cut out after a mile, but more often after an hour or so. I read somewhere on this forum about a reset by disconnecting the battery. This hasn't made any difference but I can't use the radio now. Does anyone know how to reset the radio please? Thanks, MG
