    Default 19cdti running out of ideas any advice

    Brought 06 vectra 1.9CDTI (150) estate 18months ago. 8 months ago loss of power and EML, fitted new air flow meter. Stripped and cleaned EGR and boost sensor. Car was fine but still had EML from cold start for three to four minutes. 6Months ago noticed fluctuations in temperature gauge very rarely going above seventy degrees. Car performing fine. 1 month ago EML went out car was fine, then suddenly last week sudden loss of power temperature gauge fluctuating between seventy and eight-five degrees, (loss of power making driving dangerous when pulling out of junctions).


    Had no problems starting so pretty sure EML was not heater plugs.


    Does anyone know whether temperature sender is linked to ECU? Have new sender coming tomorrow whilst fitting this will also check EGR and Boost sensor again.


    Did the 06 have a problem with the swirls?
    Are there any known vacuum hose pipes to check?
    Any ideas greatly appreciated.

    Swirls are a problem upto August 2007, which is when the new updated manifolds were fitted to the factory cars.

    Temperature gauge I think is a different issue ie a jammed opened thermostat.

    As for the loss power that is possibly the swirl flaps - ie they have jammed shut. Is the rod off? I take it from your post you haven't had the codes read in all that time? If so why, it would have given you a major clue and you would no for certain.

    had the codes read first time probs started which said airflow and temp sender, after changing airflow everything was ok 4 1 week then light on and power loss, read up on here how 2 do egr etc which fixed power loss.
    Heater is red hot even in the cold weather we had so pretty sure its not that, No 3 injector has already had mod done .
    have looked 4 swirls bar b4 but couldnt see it will have another look tmoz.
    Thanks

    In answer to your initial question the CDTI has one coolant sensor screwed into the thermostat housing. This feeds the ECU and temp gauge.
    Check the pipes that go to the turbo waste gate.

    changed temp sensor, cleaned egr, inlet manifold badly blocked, cleaned boost sensor, replaced vacuum hose to turbo small wear mark where it goes under engine cover. Checked swirls linkage (pretty sure had new manifold as new bar system with what looks like plastic bushes in it) all working ok when engine reved. STILLTHE SAME.

    Took it to engine diagnostic had it pluged in.

    NO FAULT CODES ON ECU.

    What the hell do u do next.

    Will check all turbo pipes tomoz,
    have noticed a bit of a knock from inject 3 but surely this would show up a fault?

    P1901 relates to the Diesel Particulate Filter in the exhaust being almost blocked. Realisticlly two options here, either have it removed and remap the ecu to stop it doing regens or replace the DPF with a new one. As winnie stated earlier, they are a fortune from the stealers but can be got cheaper on ebay. I suspect p0380 means the glow plug relay, it sits on the nearside chassis leg under the battery.

    Not excatly,, the DPF captures particles of soot and carries out regens to burn these off, Basically what is happening during this process, is that the engine's computer has decided from the information that it receives from the sensors installed in the exhaust, that the DPF has filled up past its acceptable limit. The computer then opens the EGR (exhaust gas recirculation) valve introducing hot exhaust into the intake, to help get exhaust gas temps higher and also injects a small shot of fuel into the cylinders when the exhaust valves are open. The raised exhaust temps and the small amount of fuel then burn out the particulate (soot) that the DPF has collected since its last regen.
    Once regeneration starts the ECU then needs to see the correct value readings from the pressure sensors in the exhaust that the filter is flowing an acceptable limit again, it ends the regen cycle.
    Normally it is only Signums, Vectra estates and autos that have a dpf. It might be that inadvertantly, you have not driven far enough or at a speed where the regen can take place, in which case you will need to have a static regen done, to see if this clears the dpf. Mine does a regen approx every 700 to 1000 miles so i am ready for it, as the worst thing you can do is switch off the engine during regen.
