    confused Huge CAN-BUS problems! 16 fault codes!

    My Siggy is causing me nightmares to no end!
    This time we have electrical problems! 16 of them in fact...I shall list the fault codes for your amusement lol

    P1614-00 - Imobiliser wrong signal received
    P1614-50 - Wrong transponder key
    P1616-00 - CIM wrong environment identifier
    P1565-71 - Cruise control interface malfunction

    B3700-0F - Wipers fault something or other I forgot
    B3715-00 - CAN-BUS no communication with UEC (underhood electrical centre)
    B3794-08 - another cruise control fault
    B3750-04 - Switch info display circuit open or high voltage

    CAN-BUS not comunicating with various instruments:
    U2103-00
    U2103-0F
    U2105-00
    U2116-00
    U2117-00
    U2125-00 - CAN-BUS no communication with GPS/TMS
    U2143-71 - Invalid data from SAS (steering angle sensor)



    Can any of you shed light on this? Is this car fit for the scrapyard?
    The Opel dealer I bought it from replaced the alternator as the voltage was too high (16.5V). They also replaced some ground cable and an LED in the clocks. Since then the steering wheel buttons don't work, I can't reset the mileage because the button is stuck, the radio goes RADIO SAFE when I switch from CD to a radio station...

    What the hell is wrong with this thing now?

    If they've had the clocks out have they left a loose or badly fitted connection behind the clocks or close by?

    I'll phone the dealer tomorrow morning. I too suspect loose connections,...I can only hope, because I really don't want to be without the car for another 2 weeks.
