   cars been off the road the last couple of weeks. so went to get her out the lockup today and the car wouldnt unlock. i used the key then when to start her up.i had dash lights when ignition was on but not enuth power to start.tried to jump start but no joy.phoned a mechanic mate and he said i may have either fooked the imobiliser so it wont reconise the card. or i may have fried the ecu. so just wondering if i get an ecu from another car will everything have to be reset at shitroen costing a bomb.

   Sounds like a good excuse to get a new re-mapped ECU if you ask me!

   Seriously though, if it is that dead, allow the battery to recharge for an hour or so from something before you try to start it again. Otherwise you can have problems.

    how do ya tell if it needs water. got the guy coming out that fitted the alarm cause there is enuth power to light the dash lights and the stereo to come on but the alarm key fob wont open the door so it may just be the immobiliser stoping the car from starting

    wouldnt bother calling a mechanic yet, charge the battery/replace, if it still dont work, then get a mechanic, the key fob not opening the doors does not mean the ecu is nackerd, just there is not enough power in the battery to work the solenoids.

    As VTRcraig said, the battery probably hasnt enough power to activate the solenoids to unlock the car.
    
    Get a multimeter on the battery and see what voltage its got.
    
    And also i think that when you use jump leads you have to put the negative lead on to an earth position, not the neg saide of the battery as that can i believe harm the ecu.
    
    Let us no how you get on, hope its not serious.

    IF you do require a new ecu then heres somewhere to try for an uncoded ecu

    Check your battery as said first tho as new ecu isnt pennies.

    I think that it is not that, an attempt by the new battery, but the first Reset the ecu and then try again

    problem solved a mate phoned me about an hour ago asking for a jump so went up with the leads i had been using on the sax. when we were conecting the neg clamp it sprung out into a million bits so just connected the wire to it and it worked.so ive just been down to the sax and tried it with that and he presto it started but still no responce from the key fob. i no have the car up at the house running fine and charged just need the alarm guy to look at the locks.

    the battery in your key fob could have gone flat making the key fob not work, does the central locking work as normal?
