    Default Poor Starting & Thick White Smoke (2.0DTI)

    Hello All ,
    My 2.0DTI has started getting harder and harder to start these days I found a quick solution which is not really feasible as i have to take the engine cover off every morning and remove the Plug from the temperature sensor bringing on the glow plugs, doing this it starts like a brand new car.
    When i dont remove the temperature sensor it starts like a tractor.

    I have changed the leak off pipes & the glow plugs but seeing as when the plugs are forced on it starts fine i am not really sure if its the Temperature sensor itself or possibly the relay any ideas? Sounds a bit lumpy in the first vid which i had not noticed before which is why i went to the engine. Thanks in advance and much appreciated.

    Also these videos are the car on start up, top 1 is when i pull out the temperature sensor bottom is attempting to start normally(usually a lot worse).

    Thanks Again

    Is it like this when the engine is cold and/or warm and/or hot?

    I'd say the temp sensor is knackered...

    It happens more or less every morning regardless of outside temperature, when the engine is cold(first start of the day) it struggles and smokes. Afternoon after being left for a while it smokes but does not struggle to start. When the engine is warm after a drive starts fine no smoke no struggle.

    Thanks.

    From what i've seen the temperature sensor are fairly cheap so if anything i hope its that ^^.

    It will probably help. Less that £10 for a genuine one if I remember correctly. I had the same issue and also did the following to sort it out. These all helped to varying degrees.

    The possible root cause (proved by removing the temparature sensor to force a pre-heat?) seems to be the engine not getting a tiny little preheat which it sometimes needs when the engine is warm, either because the ECU thinks it doesn't need one or because a sensor is faulty and leading the ECU to think that the engine is warmer than it is.

    Cleaned MAF (difficult due to security screws, got rid of hesitancy at low revs).
    Replaced crankshaft sensor (helped starting and also smoother running).
    Replaced battery (old one was way down on what it should have been, turns over a lot faster on new one).

    Is there not an ecu software update available for the 2.0 DTi cold start issue? Just remembered seen it on another thread somewhere...

    The battery i have is virually brand new, and did all these fixes sort your issue out or simply make it better than it was?
    I also seen the thread somewhere about the ECU update but not sure if the car has had it by the previous owner or how i go about it vauxhall probably charge a fortune.

    Thanks again

    The things I did (including finally replacing the oil temperature sensor at the weekend) have made the car considerably better although it's at it's worst (relatively speaking) at the moment due to the ambient air temperature being just high enough for the ECU to decide that it doesn't need to pre-heat.

    If you leave your car parked with the front end facing downhill, gravity should help stop fuel flowing back towards the tank due to air getting in somewhere. If the car is easier to start then there may well be an air leak somewhere (including the injector seals presumably) but if's its just as difficult to start then maybe the issue lies elsewhere.

    I went to an independent Vauxhall specialist who had a Tech2 and his opinion was that he couldn't see anything (fuel pressure, I think it was) that would indicate an issue with the injector seals. He also said that the 'fix' of removing the coolant temperature sensor wiring connector pointed to the issue not being related to air leaks in the fuel system but due to a faulty temperature sensor or an issue with the software version in the ECU that was not pre-heating when it needed to.
