got the same fault on mine again happening more frequently now 3779 am sure if I send it in they will do the leak test and it will be diagnosed as injector but am I right in saying if its the injector it will be on all the time example you kick it up in the morning it idles roughly for a few seconds then warning will come on turn engine off then back on again it clears it could stay off then all day or may take a number of miles to come back on again off /on away it goes could be doing 56 mph or could be ticking over for warning to come on ive cleaned the pre filter nothing much in it worth worrying about .I put it in man couple of months ago came out ok but after a week same fault what would you do ?is it worth getting injector cleaner into the system maybe into the pre filter or fuel filter
