hi there, right heres my story its doing my head in now, i went to santa pod....done a run down the strip parked up went got my time and come back to the car to go again and it wouldnt start just turns over...orange immobiliser light flashing....so being a mechanic i though maybe its my key went home got citroen diag....plugged in shows up key code read n vaild so its not the key or the ring round barrel (put new one on anyway) so then i went to unlock ecu.....shows up ecu unlocked....non virgin ecu?? (magneti marelli IAW48P2.80) so i still have the immobiliser box plugged in so maybe this has coursed it to kick back in?? but why hasnt the ecu locked and has any1 got any idears to get it going again it just turns over, light flashing, can any1 de-immobilise my ecu?
