    Default CDTI - starting up in the cool weather

    Been slightly cool this last week, and I've noticed the engine is slightly harder to start first time in the morning. Takes 3 or 4 turns to fire up, instead of instantly, as it always did previously. Also, there's a fair puff of smoke visible out of the exhaust when it fires
    Car runs perfectly after this, and no smoke at all from there on.
    If it was really cold I would expect this, as the diesel tends to go like jelly at low temperatures, but it's only been down to -5C.
    Anyone else notice this with their CDTI, or anyone have any ideas what the problem is?

    As you said it has been cold. The oil thickens up as does deisel, the various metals contract, and everything gets a little damp. Only way to stop it is to park in a heated garage.

    The puff of white/grey smoke is worrying though :/
    Just found another thread on here, and some are saying this may be a sign of a knackered injector
    Hope not, runs sweet as a nut apart from the starting.

    Wireing loom on injector 3 is prone to be give hassle.. This is the first sign - lumpy starts when cold etc etc..

    As discussed here:
    http://www.vectra-c.com/forum/showth...t=62925&page=4

    Found it on TIS, so its a well know issue from VX and for causing jerking I think they should include total engine shut down!

    Field Remedy: 2049
    Subject: Engine Z19DT/H - Jerking, somtimes Trouble Code P0201-P0204 set
    Models: Engines: Option:

    Complaint: Customer complaint about jerking sometimes SVS lamp on and DTC P0201-P0204 set.
    Cause: Software and / or fretting corrosion on injector plug.
    Production: Modified wiring harness has been implemeted in production as of engine numer: Z19DTH17000444.

    Remedy:
    In case of customer complaint reprogram ECU according TSB 1849 before changing any parts.
    If TSB 1849 will not cure the problem install field fix injector plugs (partnumber 93189918 / cataloguenumber 62 86 769).
    Mentioned Field fix kit does not contain of a 1,5mm² wire as mentioned in TIS 2000 wiring diagram.

    I beleive the white smoke is fuel, as you turning engein over couple times so it could be that amount of fuel in pot befor it fires up.

    -5C is quite cold for a diesel. The smoke is normal for a direct injection on a cold start.

    15 years ago in -5C you'd be looking at 3 or 4 cycles of the preheaters, 2 minutes of cranking, 2 or 3 stalls and about 5 minutes of blue smoke for a normal diesel. Or indeed a walk to work.

    Aha, we have a winner. I didn't know that you had to wait for the glow plug like that - tried that earlier and it's great now.
    I probably missed that in the manual - thanks for the tip.
