Dont even try, You need to put it on a Renault 'plip' machine. You could spend hours, days even checking things and changing componants all to no avail. A dealer will charge about £100 for the privilage. What about calling the AA out to the brakedown they have diagnostic equipment and might be able to pinpoint the problem and if not they will recover it to the dealer.
