    Eek Signum ECU failure!

    My 2.2Direct Signum is currently sitting at the dealer apparantly with an ECU failure.

    The car died on the motorway with the car&spanner symbol. Turns over but rough and won't start. RAC couldn't fix so towed it. Fault codes for all 4 injectors, throttle sensor and some other stuff I can't remember.

    Dealer says they clear the codes but one remains - ECU Failure.

    £840+ for a new one
    That's alot of money.

    Anybody know of a cheaper repair/replacement option?

    as Ros says ... if the ecu supply voltage is low (due to $h1tty connections) it'll throw up allsorts of ecu issues... but i'd expect other faults(sensors etc) to come up first.. but well worth checking.

    Unfortunately ECU's that have not been 'un-married' from the original car when they are removed can not be used on another one.

    I also phoned several ECU repair companies and they all said that the 2.2 ecu can not be repaired. A couple could supply brand new ones but at the £450+ mark and about a week to supply.

    Not looking good

    looking around fleabay you find most parts state they've been tech2'd off the original car. I'd try one before shelling out £450+.
