    Default vectra 1.9 cdti 150 smoking

    hi my 150 vectra has developed a missfire and started with white smoke out the back which improves as the car warms up, what could it be? I suspect an injector may be dripping into the cylinder when not running is this possible? if so how do you replace an injector and does it need to be programmed or is it a case of put a new injector in and the car will/should run, sorry forgot to mention the smoke smells of diesel not oil or water

    Sounds like injector to me you wpuld need to replace the said I Hector there is a how2 on here in the how 2 section and yes the injector needs to be programmed to the car you will need someone with opcom or tech2 to do this

    Either a leak off test or an injector specialist or opcom to see the deviation of the injectors will do


    Reprogramming is easy wit opcom all you do is delete the old injector code an type in the new one which is stamped on the injector
