Corsa dash clocks problem

    If your dash clocks are coming and going, and also an intermittent start, the problem is due to a loose connection at the back of the dash clocks. You need to remove the steering cowling, and panels to remove the clocks to fix it. When you have the clocks out, the block connector will stay mounted in the dash. To fix the problem, remove the block connector and put 2 small pieces of foam or something similar at the sides where the block connector sits to keep it pushed out a small bit. Refit the clocks and this will solve your problem. The reason it fails to start when the clocks are not working is that the engine ECU has to recieve a signal for the immobiliser which comes from the clocks.

    If you had a similar problem where you were just losing the rev counter, and intermittent non start, it is a problem with the Crankshaft position sensor. Usually will start when cold but when it heats up it will not start.

    i'd just like to thank boards.ie and 'lucifer'

    my girlfriends '03 opel corsa 'c' has had this intermittent dash failure
    for about a month now,she left her car into a main opel dealer in dublin
    for her annual service (same place the last 4 years)
    as soon as we mentioned the speedo the guy at the desk finished our sentance!! so this must be a very common fault.
    we asked them to ring us with a price for any extras before doing them to make sure,
    they told us that to fix the speedo fault we
    "needed a new speedo wiring loom at a cost of €180"
    we decided not to have it done at this time,

    long story short i checked boards.ie
    came across this thread,decided to give it ago meself,
    only to find in a little over an hour i had the dash back together and the problem fixed! WOOHOO!
    :D

    JUST A WORD OF WARNING TO ANYONE WITH THE SAME PROBLEM
    there is no "replaceable" wiring loom for the speedo
    the speedo plugs directly into your cars main wiring harness!


    a main opel dealer were going to charge us €180
    for a part that doesnt exist!:mad:
    so i can only assume
    they wanted €180 for what would take a qualified mechanic
    about a half an hour which is scandalous!:eek:

    as above thank you boards.ie and thank you 'lucifer'

    Hi  lilp4130 and Lucifer,
    I have exactly same problem. my mechanic replaced CIM but still it is not fixed yet. Can you please send me a detail description of how to check the block connector as I would like to do it by myself? I have already spent a lot on this still no results.
    Thanks and appreciate your help J
