hi ive owned the car for a year now and it always had this rough idle now and then tried injector cleaner but no improvement and serviced it still same.
its strange it drives fine and ticks over OK most of time just every so often the lumpy tick over kicks in
any advice would be much appreciated

Has the car ever had the timing belt replaced as recommended by Renault i.e ,

1.5dCi, 2002-10,60,000 mls or 72 Months?

Better to get a proper diagnostic check carried out rather than guessing .Could be a fuel pressure regulator fault or an injector to name a few but many other possible causes .
