Hi, few days after I bought it my c3 cut out in the middle of a motorway. After that it would not start. I got a car checked in a garage only to be told that no fault was found. Now it seems the car starts 1 time out of 10. It's 2008, petrol, 1.4.any ideas where to start looking? Citroen service would charge me silly money just for checking the car thanks for your help
