    confused Signum Starts for 7 seconds

    Hi All,

    When the ignition is turned on I get a spanner symbol on the Tacho, if I start the car (2.2 DTI) the engine will run for about 7 secionds and then run down. With the bonnet up I noticed a gurgling noise that I thought was coming from 2 units with electrical connections just inboard of the nearside headlight. I disconnected the electrical connections, started the engine, spanner symbol on, and the engine remained running. With the engine running I reconnected the electrial connectors and had no further problem. Any ideas?

    Do you mean the vac solenoids on the wing? (they have some rubber tubes connected to them as well)

    No the 2 units I'm refering to are just inboard of the battery compartment and have 3 plastic/nylon pipes (Probably Air) connected to them.

    If I was in the UK or Mainland Europe I would take it to VX, but I've only recently moved to Cyprus and have yet to locate a VX/Opel dealer.

    those units ( down by the battery traybox on the chassis leg) are the vacumn solenoids... check their rubber connectors and plastic lines ( at bothe ends of the lines) very very very carefully for and splits or cracks or hairline faults...the DTi's are vacumn operated cars so any leaks cause major havoc with the running of the car..also check the filters/valves on the other side of the solenoids as well...

    Disconnect the solenoids one at a time to see if one affects more than the other..

    As Gsi3.2 says above, check the tubing for splits as this is very common (and very cheap to fix as well).

    Thanks for the replies, I've now checked the tubing/pipes and they all appear okay and I haven't had a re-occurence, so fingers crossed.

    Default Signum 2.2DTI Engine Managemnt Error Problem

    Same problem re-occurred a few weeks later and I managed to get the car to an Opel dealer and the fault codes seemed to indicate a faulty EGR valve. Now having replaced the EGR valve the problem is still occuring.

    The last 2 failures where:

    Driving about 30 MPH Spanner/Car symbol comes on and the engine runs down, I switch ignition off and after a few seconds back on the symbol is still on the car will start but after 7 seconds of idling the engine runs down. After leaving the ignition off for a while the error symbol clears and I can drive as normal.

    A few days later driving at 60 MPH Driving Spanner/Car symbol comes on and the engine runs down, I switch ignition off and after a few seconds back on the symbol has cleared and I can drive as normal.

    Back to the dealer and 1st fault code indicates high voltage from the throttle position sensor and the 2nd code indcates excessive exhaust gas recirculation.

    Anyone any ideas especially regarding the 7 seconds of idle and then running down?

    Regards

    I´ve had egr fault plus throttle control circuit negative deviation fault at the same time. Also the engine would die without a warning at any given time. Ignition OFF and start -> engine ran ok maybe a week until died again. In that case the upper part of intake manifold (with throttle position sensor) needed replacement.
