    Default 1.9 CDTi 150, juddering and spanner!

    My signum is slightly juddering at idle, but when driven it judders really bad. i have read several posts about the spanner and car light which leads me to believe i have to take it to VX for tech 2. the spanner light comes up for 5 seconds then goes off again it never stays lit?

    The car was serviced at phompreys VX on the 15 of jan with 58817, i have now done 61500 "so now outside of the warranty", the fuel filter was changed , and i only ever run on bp ultimate! and never run the fuel low. it feels like the filter is partially blocked, but reading the posts it sounds like it could be all manner of things, egr, swirl valve, various sensors, injectors etc etc..

    I will take it in to VX tomorrow for diagnostic check which reading will cost me £50+ lovely...

    Any advice for checks will be great as the sun is shining today!

    It sounds like a faulty injector mate, or it could be the swirl valve. I agree that Vx need to plug it into Tech2 for a diagnosis.

    I just had a look under the engine cover and checked electrical plugs, connections, worn pipes which all appear fine. i did find a piece of bent (corregated) ally with 4 small location cups which sit over 4 pins that are located under the common rail injector on the head, it had come off the pins which was a pig to relocate, but it still feels loose. any ideas what it is or does i will try to post a pic in a mo!

    in the pic you see the LHS end of the bent ally laying on its side, the black cup should sit over the pin sticking up from the head. any ideas???

    its your swirl control rod become disconnected from the flap. Known problem on the 1.9. take it to vaux and they should give you a nice new modified inlet manifold!! crappy job to do though!

    Thumbs down damn..........

    Hi all

    My 1st post on the vectra site, so hi everyone. Unfortunanty, I have a problem and looking at this post made me go outside at half 10 at night with a torch to see if its the same problem. I started the engine and had a look, I could see one of these 4 black cups bouncing around, so is that normal or not? I bought the car 10 weeks ago, so its still under the 3 month garage warrenty. Only problem is I live in midlands and the garage is in sheffield.

    Does it need a new inlet manifold or can it be fixed?

    Default its not a swirl valve it the egr rod?

    Just been down to Vauxhall and they say that this rod is actually the EGR control rod, they showed me one on the bench, looks like there is a something that comes up the center and allows that rod to move left/right which moves all the egr valves.

    He said he has never seen one come off like that, he also said I might be able to put it back in place but it might not last, failing that looks like its a new inlet manifold. He said it would cost about 500 squid all in. Is it possible to do this myself or is it best to get the stealers to do it.

    Thanks

    If you take the top cover off you will see the common fuel rail running across the top of the engine, if you peer down behind that you will see the EGR control rod.
