    Hey guys, I've got one of these, a 2008 model, running rough and flashing all sorts of lights on the dash telling me to stop. My super cheap Autel diagnostic device is throwing up the code for No 3 cylinder injector open circuit. This seems a likely culprit for the problem. Anyone here ever done one? I understand they can be a nightmare to get out as they corrode into the head. So I've filled up the trough on the head that the injectors sit in with WD40 and can leave it like that for a few weeks. Is there a better product for such a task?

    Also, out of interest, which is number 3? Count from the flywheel or the camchain? I can never remember with Renaults.

    Typically Renault number the cylinders starting from the flywheel end which is number 1.
    The injector is clamped in, no one can tell if it will come out easily so release the clamp and hopefully it will move. If it won't, don't get carried away, find a Bosch diesel specialist who can extract the thing without damage.

    I should have mentioned, you can tell which injector is in the huff by measuring the diesel run off.....removing the leak off pipes from each one, the faulty one will leak off much more fuel.

    I'd be surprised if you manage to get it out.

    They tend to be seized in. If it is expect it to have to go to a specialist.

    Worst case scenario and also not uncommon you'll have to get a new head.

    Is this the one where only a specific brand of diet cola will release it?

    You could try diesel, but not whilst its running, leave it overnight before trying to remove the injector. I once spent 19 hours trying to get one injector out of a Paxman Ventura 16 cylinder.

    Good luck.

    I use plus gas fast release instead of wd40 these days.

    Could be a wiring/ connection fault. I would check resistance across each injector first, should have routhly same readings on all of them.
    This will confirm if No 3 is at fault before trying to remove it.

    Cheers to all responses, I'm still letting it soak for now. I wonder has anyone here ever had any joy with the slide hammer type puller kits available on fleabay?

    Some times but be careful as they can ruin the thread on the injector if you go to mad.

    Also I had a mechanic friend who swore by using cillit bang poured down the injector tubes to soak into and ear away at the carbon.
