    Default vectra c 1.9 cdti 120 diesel judder at around 2000 revs

    Hi all,

    I have a problem where at around 2000 revs the car judders & jerks & you can hear a strange noise. Sometimes also happens if you are accelerating and then eay off on the accelerating.

    I've only just had the EGR valve changed a few day ago & didn't have any sort of problem like this before.
    Could it be related to injector 3 as I have read on similar threads?

    Any help or insight gratefully received as its driving me mad at the moment.

    Thanks
    Gary

    Had a quick look & the cover on the 3rd injector is much newer than the other 3 so presume that it has had something done to it.
    Not sure what & where boost pipes,will google & find out.

    A bit of reading so I have disconnected the EGR valve & the juddering, jerking and whooshing disappeared. It is a new unit fitted on Friday so may be the software needs updating? Re-connected the EGR & same problem starts happening.'the spanner light also went off after r-connecting.
    So another visit the dealer again on Monday.

    Might be a faulty valve they put in, these things happen. The only other thing I can think of is the MAF as that is used to detect EGR function.

    Final update, took back to the dealer & they did the software update to the ecu and car no longer judders etc, so all resolved.
