Hi there,

I would like to return the original file to my ECU on alfa 156 jtd crosswagon. I bought the car and I think that my ecu does not have the original file.

I have read that the original file will not work (I downloaded it from internet) because the immo code is saved in ECU. I have read in internet that the immo can be set to "new state" through changing hex 0x180 to 4 * 0xFF. The problem is that I can not find this adress.

Can some please help plese?

Best,

If the car runs ok but you think that it has been remapped then just load an unmodified original external flash file, just match the ecu/software id, no need to mess about with immo data if it runs ok at the moment.
