Hi all, after a lot of trouble with my immobilizer I was told to find a new ecu and clocks and replace them. I have found an ECU from the same year car (02) and same size engine (1.6). I checked the part number and all the numbers matched EXCEPT the last 2 letters. I was then told that the ECU would not work with my car. Has anyone got any experience with this? Would the ECU work?
