i had the aa out for the same problem.
he checked a few things 1st.
then removed the distributor cap. it was full of water,
he dried, cleaned it, and sprayed it with wd40.
he suggested that i replace it, but to get a match you have to take it to a proper renault place.
i make sure i got the tools to remove, dry and wipe the thing.
since he sorted it its been cool.
