just got my self a Ford Transit Connect -08 1,8 tdci.
One morning it didnt start and the immobiliser flashes error code 23.
After googling I got "23 - ECU ID mismatch (duff ECU)"
I have had a company to rematch my key with the ECU, the programing worked and the key info was saved.
But the error code remained and the car didnt start.
Can I fix this problem using a other ECU and its matchning key from another Transit Connect of right year?
Can anyone confirm what the error code means?
