    Default Injection ECU problems? - V6CDTi

    Finally got my car running after a few months of terrible cold starts and power loss issues! New SCVs fitted

    What's been bugging me since February though is the fact that the new injectors are making the same noise the old ones did. And I mean THE EXACT SAME! I checked with a screwdriver
    The old ones: nr. 1, 3, 5 were knockin;. 2, 4, 6 were ticking quietly
    The BRAND NEW ones are exactly the same! I could live with the noise, but the problem is the smokescreen the car puts out when I touch the throttle on boost. The Opel dealer has been repeatedly telling me, that the injectors on the Y30DT 3.0CDTi do not need to be reprogrammed.

    Is there a way to check if the ECU is functioning correctly? I'm talking about the black ECU on the engine, not the one that sits on top of the airbox.

    Hi . The injectors do not need to be programed. You could find a saab or vx none franchise garage or breakers to see if you could try one from another car. They don't need to be programed as I did this with mine.

    The problem would be finding a garage like that that had an ECU for the V6 diesel. Not so common lol

    my vectra V6 Cdti is very inconsistent when it comes to 'smoking,' one day it does it and the next it does not. I'm wondering if it's something to do with the fuel that is used. I.E. cheap supermarket crap diesel!

    I've had a listen to my injectors and a few of them are alot louder than the others.

    I believe you had 6 new injectors fitted a while back didnt you? Where did you source these from (if you dont mind me asking?) they could potentially be duff????

    Mine is the same. Could be fuel related, but then again I always fill up from the same pump in Koper.

    Were they on the rear bank?

    I got them on ebay. They looked brand new to me. Don't think they're duff though as fuel consumption improved when I got them fitted.

    There is the middle one on the rear bank - this is the noisiest one of the lot! sounds like a hammer!! There is one on the front bank that is 'different' to the others but I reckon it's ok!
    I can hear one injector knocking when the engine is under load in a high gear - so i'm assuming that its the one on the rear bank.

    May sound a bit daft, and I don't know how much good this will do but when I cured the smoking problem short term by using OPCOM, forcing the EGR to stay open, then revving the nuts off the car. The smoke was biblical... but it stopped smoking under normal conditions for a few weeks!

    Have I read somewhere that you've had a new EGR on your Y30DT?

    Sometimes I hear the knocking under load in high gears sometimes I don't. Weird

    I once tried revving my car in neutral a few times and then the smoke was less noticable if I booted it (still in neutral). The smoke level did not change on the move.

    The EGR that is fitted now has been used for less than 10000km
